    Full Text Available The objective of this paper is to examine and identify barriers to and enablers for the European rail freight transport services as a transport chain partner along the supply chains in the changing market scenario. The changing market scenario includes, among others, requiring 'door-to-door' rather than 'terminal to terminal' and integrated service, competitive ability to attract non-rail cargo type, changes in the customer requirements (e.g. reliable service and changes in the operational requirements and practices. Using a literature review method, the paper is presented in two parts. The part 1 focuses on the identification of barriers to the European rail freight service by reviewing freight logistics services for global supply chains followed by the current performance of European rail freight transport followed by a discussion on the rail freight market liberalisation in Europe. Then rail freight transport in the Unites States (U.S. is discussed. The research notes that although the background, scope and necessity for reform measures in Europe differ from those of the U.S., some lessons can be learned and the main lesson is that an appropriate reform measure can enhance rail sector competitive ability in Europe. The part 2 of the paper is dedicated to recommend some concrete steps and actions as enablers to remove the barriers identified in the part 1 to develop multimodal rail freight transport. The enablers for multimodal rail freight transport include: •\tEuropean rail freight transport market needs full liberalisation so that incumbent and new entrants can compete freely. •\tThe rail operators need to acquire service (e.g. customer tailored services, door to door service quality offered by road freight operators. •\tThey need to conduct a combination of ‘terminal-to-terminal’ and door-to-door operations, as and when needed; •\tThey must build partnership with freight forwarder or 3PLs to include all types of customers

    Full Text Available In this paper we discuss several consequences of the freight transnational rail liner service on the rail corridor capacity. The Northern part of the IVth TEN-T corridor on Romanian territory has specific feature related to the passenger flows connecting important Romanian demographic and economic clusters, on one side, and on the other side, to its diagonal crossing aspect, from the Western border to the Constanta port, connecting the Central Europe countries to the Black Sea regions, which means that there are a lot of expectation in terms of this corridor rail capacity: this corridor will, be for a long time further, the single and first completed continuous upgraded and modernised rail corridor. Its utilization will necessarily be heterogeneously planned (meaning for passengers rapid trains and freight rapid trains, from domestic/internal market, but especially for external market of Romania. In this paper, we consider a simple mathematical model for the calculus of capacity in two different cases: for a homogeneous utilization, meaning that all trains have the same running speeds and for heterogeneous utilization, when the passenger trains have the higher speed and hence, the higher priority over the freight trains, even if some of them are freight transnational liner service. Special feature of liner rail service has to be considered (fixed schedule, no stops for passenger train advance. We draw several useful possible solutions to be considered in order to preserve the active corridor capacity, and to assure a smooth flow for the transnational liner services, which ultimately will enhance the rail attractiveness.

    FlexCargoRail is a concept for self propelled electric freight wagons. This will enhance rail operations on first and last mile. The concept can be integrated in the existing rail system, so migration is possible without any lost investments. Standard components from industry and rail are used to realise the FCR wagon. Motors, transmissions, control and batteries are available and approved. One of the effects is to enhance service for loading terminals. This can become independent from factory siding operation. From the economic point of view, FCR is realisable. This is shown by target costing. Efficiency of FCR is dependent from high frequent use of FCR rail cars and the use of the possibility to shunt also conventional freight wagons with FCR wagons. Migration should be carried out in logistical networks with frequent operations between plants and sidings with a closed wagon pool. (orig.)

    Transshipment yards, where gantry cranes allow for an effcient transshipment of containers between different freight trains, are important entities in modern railway systems and facilitate the general shift from point-to-point transport to hub-and-spoke railway systems. Modern rail-rail transshipment yards accelerate container handling, so that multiple smaller trains with equal destination can be consolidated to a reduced number of trains without jeopardizing on time deliveries.

  7. Rail freight transportation concerns of developing economies: A Namibian perspective

    Directory of Open Access Journals (Sweden)

    Fanny Saruchera

    2017-05-01

    Full Text Available Background: Although rail transport appears to be well established and outperforming other transport modes in Europe and beyond, in the majority of developing economies it was observed that firms and travellers were, on the contrary, shunning from the rail. Despite considerable infrastructural investments in the African rail systems, the sector has been deteriorating over the years. Objectives: This study identifies the freight rail transportation problems faced by African developing economies, focusing on Namibia, and examines the potential actions and factors for minimising such problems, drawing lessons from some of the developed world’s success stories. Method: The objectives of this study are achieved through a survey of Windhoek-based industrial and logistics firms operating in Namibia. Self-administered survey questionnaires were distributed through the aid of trained research assistants. Results: The study’s results show that some of the reasons of shunning rail transport are a matter of attitude, whereas some are related to operational challenges. The study confirms that the transport mode used and ownership of the freight transport services used can affect the degree of satisfaction for the transportation of goods in Namibia. Conclusion: Namibian industrial and logistics firms avoid using rail, owing to its low level of satisfaction obtained from its use. Besides engaging in Public Private Partnerships (PPPs in rail transport operations, the study contends that rail transport should receive attention similar to that given to other transport modes for African economies such as Namibia to overcome the costs associated with the increasing road congestion.

  8. Urban freight distribution: council warehouses & freight by rail

    Full Text Available Rail is the one of the highly underused form of freight transportation in the European Union. Majority of the freightage are distributed by trucks and HGVs. With new regulations and socio-environmental concerns urban logistics is facing a new challenge which can be tackled using innovative transport mechanisms and streamline operations. This article sheds light on a system which integrates freight distribution via metro lines in the closest vicinity of the customer, use of council warehouses and further innovative transport mechanisms for final delivery. This system uses existing infrastructure effectively without impacting its surroundings and triggers the reduction of polluting carriers. This system offers the option of immediate implementation which will enable EU to compete with a global freight distribution market.

  10. A proposed regulatory framework for road and rail freight transport in South Africa

    Directory of Open Access Journals (Sweden)

    Wessel Pienaar

    2007-09-01

    Full Text Available The increase in the number of freight vehicles on South Africa’s rural road network has received substantial attention. Insinuations persist that long-distance road freight haulage is of a somewhat unsavoury economic nature, and that strict economic re-regulation of the land freight transport is necessary. During the 1970s road transport replaced rail carriage as the dominant form of long-distance freight transport (excluding minerals and ore in South Africa. On long hauls road freight carriers transport certain primary products of an organic nature (such as timber, fish and agricultural produce, some semi-finished goods, many finished goods and most consumer goods. Road freight carriers are continuously gaining market share on long-distance links where rail transport is the more cost efficient mode. The greater value added by road freight carriers in comparison with rail transport through service effectiveness is often more than the cost premium paid for utilising their service rather than making use of rail transport. Throughout history, governments have involved themselves in transport. A diverse range of arguments have been advanced for this involvement in transport, including the following:Control of excessive competition, co-ordination of transport, integration of transport with economic policy, maintenance of safety, security, and order, provision of costly infrastructure, provision of public goods, recovery of the true resource cost of transport inputs, regulation of harmful conduct and externalities, restraint of monopoly power, and social support. A set of nine instruments can be identified that governments apply to influence the performance of the freight transport industry: Legislation, direct supply, fiscal measures, monetary measures, moral appeal and persuasion, policies relating to strategic commodities, procurement policy, provision of information, and research and development.

  11. Could Expanded Freight Rail Reduce Air Pollution from Trucks?

    Science.gov (United States)

    Bickford, E. E.; Holloway, T.; Johnston, M.

    2010-12-01

    Cars, trucks and trains are a significant source of emissions that impact both climate and air quality on regional to global scales. Diesel vehicles, most used for freight transport, account for 42% of on-road nitrogen oxide emissions, 58% of on-road fine particulate emissions, and 21% of on-road carbon dioxide emissions. With freight tonnage projected to increase 28% by 2018, and freight trucks the fastest growing source of transportation emissions, we evaluate the potential for increased rail capacity to reduce the environmental impacts of trucks. Most widely available mobile source emissions inventories contain insufficient spatial detail to quantify realistic emission scenario options, and none to date have been linked with commodity flow information in a manner appropriate to consider the true potential of rail substitution. To support a truck-to-rail analysis, and other policy assessments requiring roadway-by-roadway analysis, we have developed a freight emissions inventory for the Upper Midwest based on the Federal Highway Administration’s Freight Analysis Framework version 2.2 and the Environmental Protection Agency’s on-road emissions model, Mobile6.2. Using a Geographical Information System (GIS), we developed emissions scenarios for truck-to-rail modal shifts where 95% of freight tonnage on trips longer than 400 miles is shifted off of trucks and onto railways. Scenarios will be analyzed with the Community Multiscale Air Quality (CMAQ) regional model to assess air quality impacts of associated changes. By using well-respected transportation data and realistic assumptions, results from this study have the potential to inform decisions on transportation sustainability, carbon management, public health, and air quality.

    2010-01-01

    In modern rail-rail transshipment yards huge gantry cranes spanning all railway tracks allow for an efficent transshipment of containers between different freight trains. This way, multiple trains loaded with cargo for varying destinations can be consolidated to a reduced number of homogeneous trains, which is an essential requirement of hub-and-spoke railway systems. An important problem during the daily operations of such a transshipment yard is the train location problem, which assigns eac...

  17. Evaluation assessment of Rail Freight Transportation Research and Development Program

    Energy Technology Data Exchange (ETDEWEB)

    1983-02-01

    This report presents an evaluation assessment of the Canadian Rail Freight Transportation Research and Development (R and D) Program. The assessment was to assist in preparing for an evaluation of the Program and to stimulate a better understanding of the broader issues and problems of evaluating R and D programs. In general, the objectives of the program are aimed at improving rail freight productivity, capacity, safety, cost, and the domestic and foreign competitive position of railway suppliers. This is to be acccomplished by stimulating a stronger industry commitment to R and D and inducing investment in new technology through joint federal-industry funding and participation in rail freight R and D projects. In view of the low funding levels of the Program, it is unlikely that it will have a significant direct impact upon these ultimate objectives. Impacts will likely only be achieved through the Program's ability to stimulate increased industrial R and D and investment in new technology. A model of the Program developed in the report shows that the critical linkages between the activities and objectives of the Program are the leadership or advocacy functions performed by the Program's managers and of the results of projects supported under the Program; and the processes of program planning and project selection. An assessment of the Program's structure indicates that there are no significant issues that would make the evaluation of the Program or its major components inadvisable. Twelve potential evaluation questions and the basic approaches required to address each of them are presented in the report. 5 figs., 10 tabs.

  2. South Africa’s freight rail reform: A demand-driven perspective

    Directory of Open Access Journals (Sweden)

    Jan H. Havenga

    2014-11-01

    Full Text Available During the 20th century, freight transport in South Africa was employed to attain politicoeconomic ideals, resulting in the overprotection of rail and overregulation of road transport. Increasing industry pressure, combined with the international deregulation trend, led to deregulation in 1988. Myopia resulted in a rail investment hiatus and exponential growth in high-value, long-distance road transport, causing excessive logistics and externality costs for the country. The aim of this study was to propose a freight rail reform agenda based on, (1 lessons from past freight transport policy efforts and (2 the results of freight transport market segmentation driven by models developed over the past two decades. For the study, freight flows were modelled by disaggregating the national input–output model into 372 origin–destination pairs and 71 commodity groups, followed by distance decay gravitymodelling. Logistics costs were calculated by relating commodity-level freight flows to the costs of fulfilling associated logistical functions. The standard management approach of founding strategy development on market-driven segmentation provides a neutral input to steer rail reform discussions in South Africa. Market segmentation points to a dualistic rail reform agenda, enabling both a profit-driven core and a development-driven branch line network. Freight flow insights are steering the policy reform debate towards long-term freight strategy development and optimal freight logistics network design.

    Full Text Available In the last decade freight transport has gained further momentum in Australia, partly through significant demand growth at both domestic and international levels and partly as the result of Australia's long term need for infrastructure decision making. Amongst the freight task, non-bulk freight is the fastest growing freight task in Australia and is forecast to grow much faster than the rate of population growth and the average national GDP growth. However, rail's share in the non-bulk market has declined significantly in the last four decades. This study therefore provides an insight into the efficiency and operational management issues facing by the Australian non-bulk rail sector by focusing on three areas; the level of track compatibility and the relevant operational issues, the demographics of non-bulk freight in Australia and the current status of intermodal terminals in relation to rail connectivity and location. As the result, a more detailed understanding of the current shortages in the Australian non-bulk rail freight sector is achieved and managerial implications are provided.

    To analyse the relationship between coping strategy and occupational stress in rail freight dispatchers. 115 rail freight dispatchers were investigated by using group sampling method, investigation contents included coping strategies, occupational stressors, strains and personalities. The proportion of using coping strategy in rail freight dispatchers is lower. The scores of job future ambiguity, type A behavior and work locus of control in workers with insufficient coping strategy were higher than those in workers with sufficient strategy (P family balance, job involvement coping factors of coping strategy were remarkable significant (P 0.05). Logistic regression analysis showed that risk of being job dissatisfaction and daily life stress in workers with insufficient social support coping was three or four times than those with sufficient coping (OR = 3.06 or 4.38, respectively), risk of being daily life stress in workers with insufficient job involvement coping was three times than those with sufficient coping (OR = 3.26). The proportion of using coping strategy in rail freight dispatchers is lower. Coping strategy has influence on the individual's perception of occuaptional stressors, strains and personalities.

    Freight transportation represents about 9.5% of GDP, is responsible for about 8% of greenhouse gas emissions and supports the import and export of about 3.6 trillion in international trade; hence it is important that our national freight transportation system is designed and operated efficiently and embodies user fees and other policies that balance costs and environmental consequences. Hence, this paper develops a mathematical model to estimate international and domestic freight flows across ocean, rail and truck modes which can be used to study the impacts of changes in our infrastructure as well as the imposition of new user fees and changes in operating policies. This model is applied to two case studies: (1) a disruption of the maritime ports at Los Angeles/Long Beach similar to the impacts that would be felt in an earthquake; and (2) implementation of new user fees at the California ports.

    This report summarizes our evaluation of the potential energy-use and GHG-emissions reduction achieved by shifting freight from truck to rail under a most-likely scenario. A sensitivity analysis is also included. The sensitivity analysis shows changes in energy use and GHG emissions when key parameters are varied. The major contribution and distinction from previous studies is that this study considers the rail level of service (LOS) and commodity movements at the origin-destination (O-D) level. In addition, this study considers the fragility and time sensitivity of each commodity type.

  10. How shift scheduling practices contribute to fatigue amongst freight rail operating employees: Findings from Canadian accident investigations.

    Science.gov (United States)

    Rudin-Brown, Christina M; Harris, Sarah; Rosberg, Ari

    2018-02-01

    Canada's freight rail system moves 70% of the country's surface goods and almost half of all exports (RAC, 2016). These include dangerous goods. Anonymous survey of freight rail operating employees conducted by the Teamsters Canada Rail Conference (TCRC, 2014) revealed that many do not report getting enough sleep because of their work schedules, and that fatigue may be affecting their performance at work. Besides general impairments in attention and cognitive functioning, fatigue in railway operating employees slows reaction time to safety alarms and impairs conformance to train operating requirements. Shift scheduling practices can contribute to sleep-related fatigue by restricting sleep opportunities, requiring extended periods of wakefulness and by disrupting daily (circadian) rhythms. The primary goal of accident investigation is to identify causal and contributing factors so that similar occurrences can be prevented. A database search of Transportation Safety Board (TSB) rail investigation reports published in the 21-year period from 1995 to 2015 identified 18 that cited sleep-related fatigue of freight rail operating employees as a causal, contributing, or risk finding. This number represents about 20% of TSB rail investigations from the same period in which a human factors aspect of freight train activities was a primary cause. Exploration of accident themes suggests that management of fatigue and shift scheduling in the freight rail industry is a complex issue that is often not conducive to employee circadian rhythms and sleep requirements. It also suggests that current shift scheduling and fatigue management practices may be insufficient to mitigate the associated safety risk. Railway fatigue management systems that are based on the principles of modern sleep science are needed to improve scheduling practices and mitigate the ongoing safety risk. Crown Copyright © 2018.

  11. Sub-Saharan Africa’s rail freight transport system: Potential impact of densification on cost

    Directory of Open Access Journals (Sweden)

    Anneke de Bod

    2010-11-01

    Full Text Available The main response to sub-Saharan Africa’s (SSA challenges has been foreign aid. Yet, despite the large amounts received, the challenges remain. There is an opportunity to consider a different model with less focus on aid and more on investment. In the transport sector specifically, investment decisions should be informed by a longterm optimal balance between different transport modes. The research presented in this paper highlights the significant cost reduction opportunities possible through the densification of rail freight, especially over longer distances, with concomitant implications for increased profitability for rail operators. The densification opportunity should also place a core focus on transport corridors being developed throughout the region. SSA countries themselves can play a critical role in unlocking this potential through, inter alia, simplifying regional economic communities and taking the lead in structuring agreements with the international community.

  13. Coopetition in Intermodal Freight Transport Services

    Directory of Open Access Journals (Sweden)

    Jian Liu

    2015-01-01

    Full Text Available The paper studies the coopetition of the downstream different carriers by providing complementary transport services in intermodal freight transport chain. Considering different information structure, a two-stage dynamic game model with simultaneous actions on investment and price is first formulated. Equilibria show both parties have motivation to select coopetition even if the agreement for cooperation investment is reached in advance. When both firms agree on the specific allocation, the new coopetition with higher efficiency would be emerged. Moreover, we analyze the complexity and evolution of coopetition by repeated pricing game with finitely and infinitely time horizon. In the finitely repeated pricing game, both firms have incentive to reach a tacit understanding to alternate choosing price cooperation and competition after setting suitable allocation scheme; the repeated periods t are then going to be an issue. In the infinitely repeated pricing game, the perfect cooperation is realized by designing the suitable trigger strategy.

    Brake squeal is a result of a unstable flutter from brake system, it results to the noise pollution in railway side and excessive wear of wheel tread. A finite element model of brake system for rail freight vehicle is set up, the contact and friction between the brake shoe and wheel tread is considered, the complex modals of brake system are calculated, the possibility of happening chatter and squeal noise are analyzed. The results show that the pressure angle or the brake force direction have a important influence on the unstable chatter and squeal noise, the more greater the pressure angle deviates from the wheel center, the more greater the possibility of happening chatter and squeal noise is, and the possibility of happening chatter and squeal noise is also increased along with the addition of friction factor.

  16. On Transport Service Selection in Intermodal Rail/Road Distribution Networks

    Directory of Open Access Journals (Sweden)

    Christian Bierwirth

    2012-11-01

    Full Text Available Intermodal rail/road freight transport constitutes an alternative to long-haul road transport for the distribution of large volumes of goods. The paper introduces the intermodal transportation problem for the tactical planning of mode and service selection. In rail mode, shippers either book train capacity on a per-unit basis or charter block trains completely. Road mode is used for short-distance haulage to intermodal terminals and for direct shipments to customers. We analyze the competition of road and intermodal transportation with regard to freight consolidation and service cost on a model basis. The approach is applied to a distribution system of an industrial company serving customers in eastern Europe. The case study investigates the impact of transport cost and consolidation on the optimal modal split.

    2011-11-01

    Full Text Available This paper evaluates service quality in the Durban freight transportation industry, in which a high degree of competition exists. Previous measurements of service quality in the industry have been casual gauges, rather than a formalised process. This paper makes a contribution by examining the level of service quality, specifically from a tangibles, reliability and responsiveness perspective, thereby identifying service quality gaps which need to be closed, with a view to raising service quality levels in the industry. The SERVQUAL instrument has been used to measure service quality levels administered to 500 of the industry’s active customers, i.e. organisations utilising the services of the freight transportation industry. The targeted respondents were managers responsible for logistics in their organisations. It was found that gaps existed between expectations and perceptions of service quality on 14 of the 15 measured items. Recommendations are made as to how the industry can improve its service quality levels.

    1995-11-01

    The freight (cargo) transportation sector accounts for a major use of fossil fuels and contributes significantly to greenhouse gas emissions. A study was conducted to assess the prospects, in terms of CO 2 emission reduction, of alternatives to present freight distribution, especially alternatives involving the use of rail instead of truck. Statistical data for Ontario freight transportation were analyzed for fuel consumption, CO 2 emission and cost consequences. Railway fuel consumption was calculated for detailed routing descriptions using a model that computed route and service specific fuel use. The information was compared directly with truck fuel consumption. It was determined that shippers who needed quick, accurately timed shipments preferred trucking over rail, while price conscious shippers, or those with heavy loading commodities preferred rail. An important goal of the study was to identify the enormity of the challenges involved, and clarify the potential tradeoffs by showing different strategies, with respect to CO 2 reduction and related economic impacts. refs., tabs., figs

  15. Sustainable freight transport in South Africa:Domestic intermodal solutions

    Directory of Open Access Journals (Sweden)

    Jan H. Havenga

    2011-11-01

    Full Text Available Due to the rapid deregulation of freight transport in South Africa two decades ago, and low historical investment in rail (with resultant poor service delivery, an integrated alternative to road and rail competition was never developed. High national freight logistics costs, significant road infrastructure challenges and environmental impact concerns of a road-dominated freight transport market have, however, fuelled renewed interest in intermodal transport solutions. In this article, a high-level business case for domestic intermodal solutions in South Africa is presented. The results demonstrate that building three intermodal terminals to connect the three major industrial hubs (i.e. Gauteng, Durban and Cape Town through an intermodal solution could reduce transport costs (including externalities for the identified 11.5 million tons of intermodalfriendly freight flows on the Cape and Natal corridors by 42% (including externalities.

  19. High speed rails. Fatigue behaviour

    International Nuclear Information System (INIS)

    Duart, J. M.; Pero-Sanz, J. A.; Verdeja, J. I.

    2005-01-01

    In recent years, passenger train speed and freight train load have increased to enhance efficiency of rail road transportation. These trends have increased the severity of rail service conditions, calling for rails with greater wear resistance, strength and fatigue behaviour. In the United Stated and Europe, track site weld rails are made entirely by aluminothermic process. This work describes the results of experimental study conducted on bending fatigue strength of plain rails and aluminothermic welded rails with preheating procedures (oxipropane and air-induced propane) approved by railways authorities. Compliance with the required fatigue strength shall be ascertained by 4 point pulsating bending test in accordance with European standards by aluminothermic welding in rails. The locati method, based in the empirical Miner's law about the cumulative damage on a fatigue tested material, allows, once known the Wohler curve of the welding process in use to settle the fatigue tensile limit at 50% with only one test. The values obtained at 2.10''6 cycles for plain rails (S f =353 MPa), oxipropane preheated aluminothermic weld rails (S f =225 MPa), and propane-air induced aluminothermic weld rails (S f =210 MPa) are very similar to those resulting from test method stated in the European Standard. From our point of view and due to its ease, speediness and savings, this is the most suitable test to check the quality and compare the aluminothermic processes in use. (Author) 15 refs

    Plans for a new high-speed rail (HSR) transportation system in Florida were reviewed. HSR is believed to be the least expensive, most energy-efficient and least environmentally harmful alternative to air and highway travel. The system in Florida will be used as a case study to determine its overall impact on the environment, people and economy. The 300-plus mile system will move travelers at speeds of over 200 mph between Miami, Orlando, and Tampa. The study will identify the impacts of a HSR system on existing transportation networks, environment, energy, growth and growth distribution, safety, economy, travel time, and tourism. Transportation problems and the innovative mechanisms needed to realize the joint public and private venture approach to planning, locating, permitting, managing, financing, constructing and maintaining an inter-regional HSR line for the state were studied. The all-electric train would greatly help the environment in two ways: (1) zero emissions from the train itself, and (2) the reduction of trips by automobile and aircraft would reduce the amount of fuel and energy being used. 4 refs., 1 fig.

  6. Freight Shuttle System: Cross-Border Movement of Goods

    Energy Technology Data Exchange (ETDEWEB)

    Levien, Mary

    2011-05-31

    The Freight Shuttle System (FSS) is designed to provide freight transportation services between those short and intermediate distance locations (within 600 miles) that are currently handling large volumes of freight traffic. Much like trucks, the FSS's transporters are autonomous: each transporter has its own propulsion and travels independently of other transporters. Inspired by railroads, each FSS transporter has steel wheels operating on a steel running surface and can carry either a standardsize freight container or an over-the-road truck trailer. However, unlike either rail or trucks, the FSS runs on an elevated, dedicated guideway to avoid the interference of other transportation systems. The objective of this report is to examine the potential viability for an alternative transportation system for trailers and containers in a multi-national, cross-border setting. The El Paso-Ciudad Juarez region serves as the environment of this analysis.

  10. CO2 emissions savings produced by the construction of an upgraded freight rail corridor. Application to Extremadura

    Energy Technology Data Exchange (ETDEWEB)

    Coloma Miro, J.F.; Garcia Garcia, M.

    2016-07-01

    Human activity since the industrial revolution through the use of fossil fuels is changing the natural composition of the atmosphere increasing the so called Greenhouse Gases (GHG). Extremadura’s government decided to react actively towards the predicted climatic variations and for that the “Strategy for Climatic Change for Extremadura” (2009-2012) was approved, which marked the strategies to follow regarding the mitigation and adaptation to climate change. Among the strategies some concrete measures are included like developing annual inventories of GHG emissions and contributing to the development and demonstration of innovative approaches, technology methods and instruments. With this objective in mind, we develop this investigation where data and conclusions dealing with the savings of CO2 emissions are given through a comparison of the actual freight transport in the area of influence of the line Badajoz-Puertollano with various scenarios of exploitation for the new planned infrastructures. The savings of the emissions will be caused by: The lowering of the emission factors (kg CO2/t·km) in the upgraded railway line in respect to the actual one. The commissioning of the upgraded line will reduce the number of lorries circulating on roads, whose emission factors in unitary terms are far more superior to those ones which will be produced by the use of the new railways. The research concludes that the commissioning of the corridor will delete 863,000 transport operations on lorries for a five-year period, reducing the CO2 emissions in relation with the road: a 59% if the traction is diesel and an 82% if it is electric.

  12. Intermodal Logistics Centres and Freight Corridors – Concepts and Trends

    Directory of Open Access Journals (Sweden)

    Norbert Wagener

    2017-09-01

    Full Text Available . Background: The development of international freight corridors, as the Trans European Network and new rail and inland shipping corridors in Asia and Africa, require efficient logistics centres along these corridors which serve as intermodal interfaces and provide a variety of different logistics service functions. The definition of the term logistics centre differs between countries and implies different functionalities. Locations are often selected randomly and business models are opportunity driven, especially in highly dynamic and less regulated new emerging economies. In particular Freight Villages as a special form of logistics centres have a high impact on regional development and serve as cargo generator for freight corridors. Consideration of general principles how to establish Freight Villages could improve the effectiveness of these logistics centres along freight corridors. Methods: Based on a literature review a comprehensive and hierarchical definition of logistics centres will be discussed and applied. From experiences in the development of logistics centres in several countries, especially in Germany and Lithuania, challenges and concepts concerning regulatory framework, determination of location and business and financing models are discussed. Results: Concerning the definition of logistics centres a hierarchical definition is applied which comprises different levels of logistics centres depending on the scope of the value adding and the functionality. As general principles for the development of Freight Villages the active role of the state, master planning, objective location finding, participation and co-operation of different stakeholders in the business model and a stepwise scheme for financing are introduced. Major trends for the future development of Freight Villages are the digitalization of supply chains, the application of new intermodal technologies and of innovative telematics systems, solutions for low emission and

  15. Changes in Service and Associated Ridership Impacts near a New Light Rail Transit Line

    Directory of Open Access Journals (Sweden)

    Jeongwoo Lee

    2017-10-01

    Full Text Available Los Angeles (LA, for many years a city with limited rail transit, is substantially expanding its public transit system. This paradigm change in transportation policy and investment creates new requirements for monitoring. One area needing evaluation is whether new, high quality transit options, such as light rail, near existing transit services increase sustainable transportation mode shares and reduce car travel. Few studies have explored light rail’s role as a catalyst to increase overall transit use and achieve sustainability goals within an auto-oriented city like LA. Metro’s data show that trips taken on its bus and rail system dropped overall by 10.5% between 2009 and 2016, but its rail ridership grew 21% during the same period due to the debut of the Gold Line and Expo Line extensions. We analyze changes to bus service and associated ridership impacts that resulted from the opening of these two LRT lines in LA. The immediate effect of the city’s bus service changes along the Gold Line light rail extension appear to be associated with a net “bus plus rail” ridership decline in that corridor. In contrast, the Expo Line corridor experienced an initial increase in ridership during the two years immediately after its opening, possibly because the bus service was not reduced by the same magnitude as along the Gold Line extension. Our findings indicate that changes in bus service made to coincide with the introduction of new light rail transit (LRT can negatively affect the overall transit ridership in the corridor. Planners and policy makers should closely monitor changes in bus service and ridership associated with new rail transit to ensure investments results in an overall net increase in more sustainable travel.

    Intermodal rail yards are important nodes in the freight transportation network, where freight is organized and moved from one mode of transport to another, critical equipment is serviced, and freight is routed to its next destination. Rail yard environments are also areas with multiple sources of air pollutant emissions (e.g., heavy-duty vehicles, locomotives, cranes), which may affect local air quality in residential areas nearby. In order to understand emissions and related air quality impacts, two field studies took place over the time span of 2010-2012 to measure air pollution trends in close proximity to the Inman and Tilford rail yard complex in Atlanta, GA. One field study involved long-term stationary monitoring of black carbon, fine particles, and carbon dioxide at two stations nearby the rail yard. In addition, a second field study performed intensive mobile air monitoring for a one month period in the summer of 2012 at a roadway network surrounding the rail yard complex and measured a comprehensive array of pollutants. Real-time mobile particulate measurements included particle counts, extinction coefficient, black carbon via light-absorption and particle incandescence, and particle composition derived by aerosol mass spectrometry. Gas-phase measurements included oxides of nitrogen, sulfur dioxide, carbon dioxide, and air toxics (e.g., benzene). Both sets of measurements determined detectable local influence from rail yard-related emissions.

  20. Reduction of Sleep Deprivation and Fatigue in Mass Transit Rail Operators.

    2017-08-01

    Sleep and work schedules differ considerably between rail workers and the broader U.S. workforce. Due to extended work hours and night shift schedules, train and engine service workers who operate passenger trains or move freight are most vulnerable to fatigue. This article addresses the need for comprehensive fatigue risk management systems (FRMS) for rail operators. Using a transactional ergonomic perspective, FRMS are discussed with a focus on fatigue education and administrative controls to reduce feelings of tiredness, low motivation, poor concentration, and low physical activity among mass transit rail operators. Recommendations for intervention implementation and evaluation are provided.

    The freight (cargo) transportation sector accounts for a major use of fossil fuels and contributes significantly to greenhouse gas emissions. A study was conducted to estimate and forecast emissions from transportation in Ontario, by mode, over the next 15 years, and to examine ways in which those emissions could be reduced. Published data of freight transportation industries was used to examine the fuel consumption characteristics of each mode, followed by a review of emission rates. It was determined that truck transportation accounts for most CO 2 emissions (about 70%). Rail follows with 21% and the marine and air modes contribute relatively small shares (6% and 2%). New intermodal technologies being introduced by the railways were discussed. They have been designed to make intermodal transport more accessible to a wider segment of the freight market. A recommendation was made which would require all truck shipments over 500 km, accounting for fully one half of truck tonne-km, to have their line-haul component diverted to this new more fuel-efficient mode (i.e., from truck to rail). refs., tabs., figs

  5. Global Trade, Local Impacts: Lessons from California on Health Impacts and Environmental Justice Concerns for Residents Living near Freight Rail Yards

    2014-01-01

    Global trade has increased nearly 100-fold since 1950, according to the World Trade Organization. Today, major changes in trade are occurring with the advent of mega-ships that can transport thousands more containers than cargo ships now in use. Because global trade is expected to increase dramatically, the railroad industry—in the U.S. alone—has invested more than $5 billion a year over the past decade to expand rail yards and enhance rail routes to transport goods from ports to retail destinations. This article describes cancer risks for residents living in close proximity to rail yards with emissions of diesel particulate matter pollution from locomotives, trucks and yard equipment. The article examines the demographics (income, race/ethnicity) of populations living in the highest estimated cancer risk zones near 18 major rail yards in California, concluding that the majority are over-represented by either lower-income or minority residents (or both). The authors also describe a review of the news media and environmental impact reports to determine if rail yards are still being constructed or expanded in close proximity to homes and schools or in working class/working poor communities of color. The paper suggests policy efforts that might provide more public health protection and result in more “environmentally just” siting of rail yards. The authors conclude that diesel pollution from rail yards, which creates significant diesel cancer risks for those living near the facilities, is an often overlooked public health, health disparities and environmental justice issue in the U.S. The conclusions are relevant to other countries where international trade is increasing and large new intermodal rail facilities are being considered.

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available The Accelerated and Shared Growth Initiative for South Africa (AsgiSA identified South Africa's freight logistics challenges as among the key binding constraints on the country's growth aspirations. The research presented here points to the structural imbalance between road and rail freight transport as one of the key contributors to this state of affairs. Most long-distance corridor transport has been captured by road. However, long-distance transport is a market segment that is very suitable for intermodal transportation : rail is utilised for the high-density, long-distance component and road for the feeder and distribution services at the corridor end points. A market segmentation approach is developed to identify the corridors and industries that are natural candidates for such solutions, thereby paving the way for role-players and stakeholders to initiate a dialogue on the development of appropriate solutions.

    Connelly, C. [Direct Rail Services, Warrington (United Kingdom)

    2004-07-01

    Direct Rail Services (DRS) has been operating since October 1995, following the decision by parent company, British Nuclear Fuels (BNFL), to create a strategic rail transport service. The decision came after the privatisation of the rail network in the UK, when the former British Rail was superseded by a range of private organisations responsible for separate areas of the industry. Individual companies became responsible for aspects such as the operation and maintenance of the network infrastructure and for passenger and freight train services. Rather than enter into contractual arrangements with third party contractors, DRS was formed - securing both the access and reliability of transport routes and availability of the rail network, providing greater guarantees about the levels of service delivery. The strategy of bringing this area of transport in house was concurrent with that of international transport, utilising its own fleet of ships for overseas fuel movements. Freight operations began in October 1995, with the first services operating between Sellafield and the low level radioactive waste facility at Drigg.

  14. Defining Robust Recovery Solutions for Preserving Service Quality during Rail/Metro Systems Failure

    Directory of Open Access Journals (Sweden)

    Luca D'Acierno

    2016-11-01

    Full Text Available In this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. Indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. In this context, the use of rail simulation is vital: for each intervention strategy it provides the evaluation of interactions and performance analysis prior to actually implementing the corrective action. However, in most cases, simulation tasks are deterministic and fail to allow for the stochastic distribution of train performance and delays. Hence, the strategies adopted might not be robust enough to ensure effectiveness of the intervention. We therefore propose an off-line procedure for disruption management based on a microscopic and stochastic rail simulation which considers both service operation and travel demand. An application in the case of a real metro line in Naples (Italy shows the benefits of the proposed approach in terms of service quality.

The paper investigates the magnitude of this ‘‘structural inelasticity” of modal substitution in freight transport due to a sparser layout of rail and ship-based freight networks compared to road. In the analysis we use a recent Scandinavian freight demand model covering more than 800...... zones. We find that the structural inelasticity is very significant – in particular for transportation over less than 500 km. Moreover, the inelasticity varies greatly with commodity groups and between OD pairs, and it depends strongly on the port and rail infrastructure. The results suggest that pure...

    1980-01-01

    This paper examines feasibility design concepts and feasibility studies of Fleet Servicing Facilities (FSF). Such facilities are intended to be used for routine servicing, preventive maintenance, and for performing requalification license compliance tests and inspections, minor repairs, and decontamination of both the transportation casks and their associated rail cars or tractor-trailers. None of the waste handling plants in the United States presently receiving radioactive wastes have an onsite FSF, nor is there an existing third party facility providing all of these services. This situation has caused the General Accounting Office to express concern regarding the quality of waste transport system maintenance once the transport system is placed into service. Thus a need is indicated for FSFs or their equivalent at various radioactive materials receiving sites. This paper also compares the respective capital costs and operating characteristics of the following three concepts of a spent fuel cask transportation FSF; integrated FSF, colocated FSF, and independent FSF

The site currently lacks rail service and an existing rail right-of-way. If the site is suitable and selected for development as a disposal site, rail service is desirable to the Office of Civilian Radioactive Waste Management Program because of the potential of rail to reduce number of shipments and costs relative to highway transportation. This preliminary report is a summary of progress to date for activities to identify and evaluate potential rail options from major rail carriers in the region to the Yucca Mountain site.

  4. Freight corridor performance measurement system: A framework for South Africa

    Directory of Open Access Journals (Sweden)

    Jan H. Havenga

    2016-11-01

    Full Text Available Background: On a national level, South Africa’s freight logistics industry is inefficient. The country ranks 36th out of 40 countries in terms of transport productivity (tonne kilometres as a ratio of gross domestic product, or GDP; the ratio of freight logistics costs to GDP measured 11.1% in 2013, compared to that of developed regions which measures in the order of 9%; and rail tonne-km market share on the two most dense long-distance corridors, namely, GautengDurban and Gauteng-Cape Town, is only 12.8% and 4.4%, respectively, whereas rail is globally acknowledged as a more efficient provider of long-distance freight solutions, given appropriate investments and service commitments. Objectives: A cornerstone of improved national freight logistics performance is the availability of reliable indicators to quantify the efficiency and capacity of the logistics network over the intermediate and long term, thereby enabling an evidence-based policy and investment environment. The objective of this article is to describe the foundation framework (i.e. phase 1 for South Africa’s freight corridor performance measurement system (CPMS. Once populated, the CPMS will be a key generator of indicators to facilitate the systemic management of corridors as a national production factor and thereby contributing to South Africa’s competitiveness. Method: The design of South Africa’s CPMS was informed by desktop research and refined through an extensive stakeholder consultation process. A distinction was made between South Africa’s dedicated bulk corridors and the multi-modal corridors. Results: Facilitating both stakeholder involvement and agreement on key indicators, as well as the eventual development of a system supporting the population, aggregation and dissemination of the CPMS are critical outcomes for the management of corridors as a national production factor. Three overarching corridor indicators were defined, relating to increased throughput

    2017-10-01

    A full nonlinear physical 'in-service' model was built for a rail vehicle secondary suspension hydraulic damper with shim-pack-type valves. In the modelling process, a shim pack deflection theory with an equivalent-pressure correction factor was proposed, and a Finite Element Analysis (FEA) approach was applied. Bench test results validated the damper model over its full velocity range and thus also proved that the proposed shim pack deflection theory and the FEA-based parameter identification approach are effective. The validated full damper model was subsequently incorporated into a detailed vehicle dynamics simulation to study how its key in-service parameter variations influence the secondary-suspension-related vehicle system dynamics. The obtained nonlinear physical in-service damper model and the vehicle dynamic response characteristics in this study could be used in the product design optimization and nonlinear optimal specifications of high-speed rail hydraulic dampers.

    2012-12-01

    Heavy duty diesel freight trucks are the fastest growing source of highway emissions in the U.S., with domestic freight tonnage projected to double by 2050. Highway diesel vehicles currently account for 42% of on-road emissions of nitrogen oxides (NOx), 58% of on-road fine particulate (PM2.5) emissions, and 21% of on-road carbon dioxide emissions. Because most surface air quality monitors are located in densely populated areas and not rural highways, it is difficult to use ground-based observations to validate spatial trends in transportation emissions. Therefore, we have employed satellite retrievals from the OMI instrument to inform surface freight transportation inventory estimates by validating modeled tropospheric vertical column total nitrogen dioxide (NO2) against satellite observations. For this research we built a roadway-by-roadway bottom-up diesel truck emissions inventory using GIS, the U.S. Federal Highway Administration's Freight Analysis Framework (FAF) activity dataset, and the U.S. Environmental Protection Agency's MOVES emissions model. We use freight rail emissions from the Eastern Regional Technical Advisory Committee (ERTAC), inventory emissions from the Lake Michigan's Air Directors Consortium (LADCO) and the EPA's Community Multiscale Air Qualiy (CMAQ) model to simulate ground-level and tropospheric column concentrations of NO2. We also use the combination of models and satellite data to evaluate weekday-weekend patterns of NO2 concentrations and the relative contributions of highway diesel vehicles, highway gasoline vehicles, and freight rail to transportation-related pollution. This research presents the first evaluation of surface freight transport from space-based observations. We find satellite retrievals of surface pollutants provide a useful data tool for evaluating air quality models and constraining emissions sources.

  12. Emissions and Air Quality Impacts of Freight Transportation

    Science.gov (United States)

    Bickford, Erica

    Diesel freight vehicles (trucks + trains) are responsible for 20% of all U.S. nitrogen oxide (NOx) and 3% of fine particulate (PM2.5) emissions - pollutants that are harmful to human health. Freight tonnage is also projected to double over the next several decades, reaching 30 billion tons by 2050, increasing freight transport activity. Air quality impacts from increased activity, trade-offs between activity and vehicle technology improvements, as well as where to make infrastructure investments that encourage sustainable freight growth, are important considerations for transportation and air quality managers. To address these questions, we build a bottom-up roadway-by-roadway freight truck inventory (WIFE) and employ it to quantify emissions impacts of swapping biodiesel blends into the Midwest diesel freight truck fleet, and investigate emissions and air quality impacts of truck-to-rail freight modal shifts in the Midwest. We also evaluate the spatial and seasonal freight performance of WIFE modeled in a regional photochemical model (CMAQ) against satellite retrievals of nitrogen dioxide (NO2) from the Ozone Monitoring Instrument (OMI). Results show that spatial and seasonal distribution of biodiesel affects regional emissions impacts. Summer high-blend deployment yields a larger annual emissions reduction than year-round low-blend deployment, however, technological improvements in vehicle emissions controls between 2009 and 2018 dwarf the impacts of biodiesel. Truck-to-rail modal shift analysis found 40% of daily freight truck VMT could be shifted to rail freight, causing a 26% net reduction in NOx emissions, and 31% less carbon dioxide (CO2) emissions. Despite significant emissions impacts, air quality modeling results showed mostly localized near roadway air quality improvements, with small regional net changes; yet, federal regulation of CO2 emissions and/or rising costs of diesel fuel could motivate shifting freight to more fuel efficient rail.

    The ever increasing problems faced by population around the world have made demands that transportation need to be improved as an effective and efficient communication means. It is considered as a necessity especially when rapid development and economic growth of a country is the agenda. Among the transportation modes being focused as critical facilities are the bus system, rail system, road network, shipping system and air transportation system. Rail transport is a means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In Malaysia, the railway network has evolved tremendously since its inception in the early 19th century. It has grown proportionally with the national development. Railway network does not only mean for rural transportation, but it also considered as a solution to urban congestion challenges. Currently, urban rail transit is the most popular means of urban transportation system especially as big cities such as Kuala Lumpur. This paper presents the definition of rail transportation system and its role in urban or sub-urban operation. It also describes the brief history of world railway transportation including a discussion on Malaysian rail history perspective.

    Freight transportation modes—truck, rail, water, air, and pipeline—each serve a distinct share of the freight transportation market. A variety of factors influence the modes chosen by shippers, carriers, and others involved in freight supply chains. Analytical methods can be used to project future modal shares, and federal policy actions could influence future freight mode choices. This report considers how these topics have been addressed in existing literature and offers insights on federal policy decisions with the potential to prompt mode choices that reduce energy use and greenhouse gas emissions.

  1. COMPETITION AND PRICING OF ESSENTIAL INPUTS: THE CASE OF ACCESS CHARGES FOR THE USE OF THE ITALIAN RAIL INFRASTRUCTURE

    Directory of Open Access Journals (Sweden)

    Ugo Arrigo

    2013-12-01

    Full Text Available This paper explores the access charge for the use of the Italian rail infrastructure. Access problems arise when the provision of a complete service to end users requires the combination of two or more inputs, one of which is non-competitive (OECD, 2004. It is a well-known fact that excessive access charges mean higher prices for rail passengers and rail freight companies when using the infrastructure. We conclude that the structure of the access charge has changed significantly with the recent introduction of the HS/HC (high-speed and high-capacity network; specifically, the fixed component has lost importance, whilst the variable component reaches 94%. The results of this paper provide evidence of the access charge for HS/HC being above 13 €/km.

    Full Text Available Rail defects due to rolling contact fatigue (RCF threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European railway network demands from every infrastructure manager to have a maintenance plan for the infrastructure subsystem. Besides that, this plan includes rail inspection and strategy against RCF defects. This paper emphasizes the importance of rail inspection and early detection of RCF because the most of RCF crack should be removed in rail grinding campaigns (preventive, cyclical and corrective activities during the whole rail service life.

    Full Text Available For a better service level of a train operating plan, we propose an integrated optimization method of train planning and train scheduling, which generally are optimized, respectively. Based on the cost analysis of both passengers travelling and enterprises operation, and the constraint analysis of trains operation, we construct a multiobjective function and build an integrated optimization model with the aim of reducing both passenger travel costs and enterprise operating costs. Then, a solving algorithm is established based on the simulated annealing algorithm. Finally, using as an example the Changzhutan intercity rail network, as an example we analyze the optimized results and the influence of the model parameters on the results.

  11. Freight transport and intermodality

    OpenAIRE

    Barbero Mañanes, Eduardo

    2010-01-01

    During recent decades, there has been very substantial growth in the freight transport sector. Freight transport is increasing faster than the economy or passenger transport. Demand is increasing more rapidly than supply and is resulting in environmental and social problems. Increasing congestion, too, is affecting efficient and reliable freight distribution, and consequently having a deleterious effect on local economies. Intermodality is therefore needed to make better use of alternative mo...

  12. The need for holding tracks at major intersections for synchronizing freight-train movements with fixed-headway passenger services; Wartegleisbedarf in Grossknoten fuer Synchronisation von Gueterverkehr mit vertaktetem Reiseverkehr

    Energy Technology Data Exchange (ETDEWEB)

    Mutschink, K. [DB Netz AG, Leipzig (Germany)

    2005-05-01

    Nearly all the big railway interesections have some facilities for passenger trains and others for freight trains. Most passenger trains today run according to fixed-headway timetables. Freight movements, on the other hand, are still basically need-driven with fluctuations in both timing and volumes. Handling both types of train as harmoniously as possible on shared lines calls for a combination of the meticulous planning of timetables and the correct dimensioning of the infrastructure. It is particularly in the vicinity of major intersections, where long-distance and local passenger trains (both with their fixed headways) converge within certain time windows, that approaching freight trains can only be effectively routed from their arrival lines to their departure lines if timing is properly synchronized. This may require the provision of a number of holding tracks for freight trains, and the essence of this article is how to compute that number using a procedure based on recognized scientific-management methods as applied to railways. This approach is centred on concepts such as certain 'no go' times for freight trains and the precise matching of train paths with the infrastructure. It does, however, take other parameters into account too, and these include the performance characteristics of each line (such as minimum headways), trains approaching ahead of their scheduled time and service constraints (such as ensuring connections and maintaining balanced intervals between passenger trains). The statistical appraisal, which is performed analytically, is designed to make sure that any results that are worked out are not slavishly dependent on the timetable, since (as mentioned above) freight movements in future will continue to be subject to fluctuations in volumes and timing.

  15. Cost characteristics of tilt-rotor, conventional air and high speed rail short-haul intercity passenger service

    Science.gov (United States)

    Schoendorfer, David L.; Morlok, Edward K.

    1985-01-01

    The cost analysis done to support an assessment of the potential for a small tilt-rotor aircraft to operate in short-haul intercity passenger service is described in detail. Anticipated costs of tilt-rotor air service were compared to the costs of two alternatives: conventional air and high speed rail (HSR). Costs were developed for corridor service, varying key market characteristics including distance, passenger volumes, and minimum frequency standards. The resulting cost vs output information can then be used to compare modal costs for essentially identical service quality and passenger volume or for different service levels and volumes for each mode, as appropriate. Extensive sensitivity analyses are performed. The cost-output features of these technologies are compared. Tilt-rotor is very attractive compared to HSR in terms of costs over the entire range of volume. It also has costs not dramatically different from conventional air, but tilt-rotor costs are generally higher. Thus some of its other advantages, such as the VTOL capability, must offset the cost disadvantage for it to be a preferred or competitive mode in any given market. These issues are addressed in the companion report which considers strategies for tilt-rotor development in commercial air service.

  16. Optimization of wheel-rail interface friction using top-of-rail friction modifiers: State of the art

    Science.gov (United States)

    Khan, M. Roshan; Dasaka, Satyanarayana Murty

    2018-05-01

    High Speed Railways and Dedicated Freight Corridors are the need of the day for fast and efficient transportation of the ever growing population and freight across long distances of travel. With the increase in speeds and axle loads carried by these trains, wearing out of rails and train wheel sections are a common issue, which is due to the increase in friction at the wheel-rail interfaces. For the cases where the wheel-rail interface friction is less than optimum, as in case of high speed trains with very low axle loads, wheel-slips are imminent and loss of traction occurs when the trains accelerate rapidly or brake all of a sudden. These vast variety of traction problems around the wheel-rail interface friction need to be mitigated carefully, so that the contact interface friction neither ascents too high to cause material wear and need for added locomotive power, nor be on the lower side to cause wheel-slips and loss of traction at high speeds. Top-of-rail friction modifiers are engineered surface coatings applied on top of rails, to maintain an optimum frictional contact between the train wheels and the rails. Extensive research works in the area of wheel-rail tribology have revealed that the optimum frictional coefficients at wheel-rail interfaces lie at a value of around 0.35. Application of top-of-rail (TOR) friction modifiers on rail surfaces add an extra layer of material coating on top of the rails, with a surface frictional coefficient of the desired range. This study reviews the common types of rail friction modifiers, the methods for their application, issues related with the application of friction modifiers, and a guideline on selection of the right class of coating material based on site specific requirements of the railway networks.

  19. Why is energy use rising in the freight sector?

    International Nuclear Information System (INIS)

    Mintz, M.; Vyas, A.D.

    1991-01-01

    Trends in transportation sector energy use and carbon dioxide emissions are analyzed with an emphasis on three freight modes -- rail, truck, and marine. A recent set of energy use projections is presented and freight mode energy characteristics are discussed. Transportation sector energy use, which nearly doubled between 1960 and 1985, is projected to grow more slowly during the period 1985 endash 2010. Most of the growth is projected to come from non-personal modes (freight and commercial air). Trends in freight mode energy intensities are discussed and a variety of factors behind these trends are analyzed. Rail and marine modes improved their energy intensities during sudden fuel price rises of the 1970s. Though there is room for further technological improvement, long power plant life cycles preclude rapid penetration of new technologies. Thus, energy intensities in these modes are more likely to improve through operational changes. Because of relatively stable fuel prices, the energy share of truck operating expenses is likely to remain low. Coupled with increasing labor costs, this portends only modest improvements in truck energy efficiency over the next two decades

    2018-03-01

    Coal has been known as one of energy alternatives that has been used as energy source for several power plants in Indonesia. During its transportation from coal sites to power plant locations is required the eligible shipping line services that are able to provide the best freight rate. Therefore, this study aims to obtain the standardized formulations for determining the ocean freight especially for coal distribution based on the theoretical concept. The freight calculation model considers three alternative transport modes commonly used in coal distribution: tug-barge, vessel and self-propelled barge. The result shows there are two cost components very dominant in determining the value of freight with the proportion reaching 90% or even more, namely: time charter hire and fuel cost. Moreover, there are three main factors that have significant impacts on the freight calculation, which are waiting time at ports, time charter rate and fuel oil price.

  7. Backcasting sustainable freight transport systems for Europe in 2050

    International Nuclear Information System (INIS)

    Mattila, Tuomas; Antikainen, Riina

    2011-01-01

    European freight transport emissions and fuel consumption are projected to increase. This study focuses on long distance freight transport (LDFT) and explores possible sustainable futures through quantitative modeling. The evaluation was part of European foresight process between researchers, policy makers and freight companies (FREIGHTVISION). Greenhouse gas (GHG) emissions and energy demand of road, rail and inland waterways were estimated for an EU-27 in 2005. Development was extrapolated to 2050 based on technology and freight performance forecasts. Stakeholders found the forecasted GHG emissions and fossil fuel share unsustainable, so alternative futures were developed with backcasting. The developed emission model was run with random parameter combinations to screen a set of sustainable futures, with an 80% reduction of GHG emissions and fossil fuel share. Freight transport performance was not controlled in the backcasts, but several sustainable futures were found if significant changes in transport efficiency and energy mix are implemented. In spite of agreeing on the importance of reducing emissions, stakeholders had difficulties in choosing a preferred technological future. Simple models were found to be an effective tool for communicating the influence of various measures. Further research is recommended to screen preferable technological roadmaps from the broad range of available futures. - Research highlights: → Sustainable transport systems were explored with modeling and stakeholder workshops. → Backcasting identified technological options for reducing greenhouse gas emissions by 80%. → Improving road vehicle efficiency, engine efficiency and fuel mix showed the greatest potential.

  8. SKF Freight Transports and CO{sub 2} emissions. A Study in Environmental Management Accounting

    Energy Technology Data Exchange (ETDEWEB)

    Lindblom, Helen; Stenqvist, Christian

    2007-11-15

    In this study of CO{sub 2} emissions accounting, freight transports of the SKF company are examined. The identification of emission sources, the handling of transport activity data, the application of proper calculation methodologies, organizational aspects and questions of liability are all integrated parts of the study. Emission calculations are carried out for two specific logistics systems managed by SKF Logistics Services; the Daily Transport System (DTS) and the Global Air Freight Program. The DTS, which is based on road freight transports, operates the European distribution of finished products. It is estimated to contribute with 9 700 tonnes CO{sub 2} during 2007. Since the system is optimized to a reasonable degree, the CO{sub 2} impact per tonne-km is relatively low. Over the same period the air freight's estimated emissions are 40 000 tonnes. Together these transport activities contributes to about ten percent of the SKF total CO{sub 2} equivalents based on the reporting of 2006. Adding the emissions from the remaining transport activities that SKF utilizes will make this share increase considerably, particularly if also inbound transports are accounted for. The potential for CO{sub 2} reductions is covered by two change-oriented case studies. It can be concluded that short-sea transportation seldom is an alternative to road transports. Intermodal transports combining road and rail can, depending on the circumstances, reduce the CO{sub 2} impact considerably compared to only using road transports. Reducing transportation work by optimizing a transport activity is seen as the best option for CO{sub 2} reductions. Efforts should be put into reducing the need for air freight transports, considering the high emission levels per tonne-km. Monitoring emissions for all transport activities that falls under SKF responsibility will reduce the risk of sub optimization. Introducing system changes in order to decrease CO{sub 2} emissions will have a range of

    The developed societies have as challenge, among others, to achieve a mobility development based on economic models of low carbon and energy efficient, making it accessible to the entire population. In this context, the sustainable mobility seems to meet the economic, social and environmental needs, minimizing their negative impact. There are three factors that are relevant: (1) infrastructures; (2) modes of transport more ecological and safe, and (3) operations and services for passengers and freights.The objective of this research is to provide guidance to investment in sustainable transport infrastructures that are truly useful and effective. In particular we have studied the case of the railway, using the following information: details of the infrastructure; cost of construction (per kilometre); maintenance cost, and life cycle. This information may be relevant to consider their possible business models.The methodology of this research was focused in the detailed analysis of the infrastructure use and maintenance criteria, the market opportunities for freight development and the available data to validate the obtained results from the software tool reached in this work. Our research includes the different following aspects:• Evaluation of the supported traffic by the rail line.• Relevant items to be considered in the rail infrastructure. Defining the track, we can group items in two sets: civil and rail installations.• Rolling stock available. Locomotives and wagons are modelled to introduce the data as convenience for the user.Besides our research includes the development of software, Decision System Tool (DST), for studying the construction and maintenance cost of railway infrastructure. It is developed in a common and open source program, providing the user the interaction with the critical variable of the line. It has been adjusted using the following references: MOM PlanCargorail; EcoTransIT, and Projects funded by Framework Program of EU (New

None of the United States' waste handling plants presently receiving radioactive wastes have an on-site FSF, nor is there an existing third party facility providing these services. This situation has caused the General Accounting Office to express concern regarding the quality of waste transport system maintenance once the system is placed into service. Thus, a need is indicated for FSF's, or their equivalent, at various radioactive materials receiving sites. In this report, three forms of FSF's solely for spent fuel transport systems were examined: independent, integrated, and colocated. The independent concept was already the subject of a detailed report and is extensively referenced in this document so that capital cost comparisons of the three concepts could be made. These facilities probably could service high-level, intermediate-level, low-level, or other waste transportation systems with minor modification, but this study did not include any system other than spent fuel. Both the Integrated and Colocated concepts were assumed to be associated with some radioactive materials handling facility such as an AFR repository

  13. Private–public partnerships: A mechanism for freight transport infrastructure delivery?

    2017-02-01

    Full Text Available Background: Freight transport infrastructure is an indispensable requirement for economic growth, development and prosperity. Public–private partnerships (PPPs, as a mechanism to fund and construct freight transport infrastructure, have been suggested by many in private and public sectors. Objectives: The concept of PPPs is dealt with, and the relevance of this mechanism is expanded upon. It is clear that PPPs in the rail environment present huge challenges and complexities. The objective was to determine whether PPPs are a viable mechanism to fund freight transport infrastructure in South Africa. Method: Experiences with rail PPPs worldwide have shown that many failures occurred implementing these. The challenges and complexities of PPPs, in the freight rail environment, are highlighted together with the benefits, risks and best practices of PPPs. It is shown that suitable policies, legislation and regulations concerning PPPs are in place in South Africa. Results: A proper framework and methodology to proceed should be in place. PPPs take time and are complex. Government involvement remains essential. Firm contractual agreements between parties are essential. Risk handling, risk sharing and the magnitude of risks should be clarified with agreement on where the risks reside. Financial viability, with value for money (VfM and financial benefits for private sector role players are non-negotiable. Conclusion: Appropriate legislation for implementing PPPs must be in place while two further important elements are economic circumstances and proper project execution. Taking all these factors into consideration, the freight transport sector can only benefit from successfully negotiated and implemented PPPs.

  14. We keep on truckin': Trends in freight energy use and carbon emissions in 11 IEA countries

    International Nuclear Information System (INIS)

    Eom, Jiyong; Schipper, Lee; Thompson, Lou

    2012-01-01

    Based on detailed national and international data on freight transportation, we analyze trends in freight CO 2 emissions in 11 IEA countries from the earliest year of data availability to 2007–2010. The cross-country comparison of the freight transportation sector indicates that per capita CO 2 emissions span a wide range and are mostly determined by local needs without full knowledge or coordination with policies and practices in other countries. Over the last several decades, while many developed countries have experienced decreased coupling between total freight activity (measured in tonne-km) and income, no major indication of decreased coupling between trucking and income was found. Rather, the coupling has been strengthened in many countries due to a continued increase in the share of trucking in total freight activity. The energy intensity of trucking has exhibited very large variation among the countries, and its recent international trends are mixed, providing greater challenges to reduce freight CO 2 emissions. Modal shift toward rail away from truck presents a sizeable opportunity to reduce freight CO 2 emissions, although the potential gain varies widely among the countries. - Highlights: ► We analyze trends in freight CO 2 emissions in 11 IEA countries. ► Many of them experienced decreased coupling between freight and income. ► No major indication of decoupling was found between trucking and income. ► The energy intensity of trucking exhibited very large variation. ► The trends of trucking energy intensity are mixed. ► There is a huge opportunity of reducing emissions by shifting toward rail.

  15. The Freight Analysis Framework Verson 4 (FAF4) - Building the FAF4 Regional Database: Data Sources and Estimation Methodologies

    The Freight Analysis Framework (FAF) integrates data from a variety of sources to create a comprehensive national picture of freight movements among states and major metropolitan areas by all modes of transportation. It provides a national picture of current freight flows to, from, and within the United States, assigns the flows to the transportation network, and projects freight flow patterns into the future. The FAF4 is the fourth database of its kind, FAF1 provided estimates for truck, rail, and water tonnage for calendar year 1998, FAF2 provided a more complete picture based on the 2002 Commodity Flow Survey (CFS) and FAF3 made further improvements building on the 2007 CFS. Since the first FAF effort, a number of changes in both data sources and products have taken place. The FAF4 flow matrix described in this report is used as the base-year data to forecast future freight activities, projecting shipment weights and values from year 2020 to 2045 in five-year intervals. It also provides the basis for annual estimates to the FAF4 flow matrix, aiming to provide users with the timeliest data. Furthermore, FAF4 truck freight is routed on the national highway network to produce the FAF4 network database and flow assignments for truck. This report details the data sources and methodologies applied to develop the base year 2012 FAF4 database. An overview of the FAF4 components is briefly discussed in Section 2. Effects on FAF4 from the changes in the 2012 CFS are highlighted in Section 3. Section 4 provides a general discussion on the process used in filling data gaps within the domestic CFS matrix, specifically on the estimation of CFS suppressed/unpublished cells. Over a dozen CFS OOS components of FAF4 are then addressed in Section 5 through Section 11 of this report. This includes discussions of farm-based agricultural shipments in Section 5, shipments from fishery and logging sectors in Section 6. Shipments of municipal solid wastes and debris from construction

  16. Trends in passenger transport and freight energy use in Spain

    Mendiluce, Maria; Schipper, Lee

    2011-01-01

    This paper provides for the first time a complete analysis of recent trends in activity, carbon emissions, modal shares, energy intensities, vehicle use and fuels in the Spanish transport system from 1990 to 2008 and discusses policy options. Passenger and freight activities have increased in Spain and are projected to continue, presenting a challenge for sustainable mobility efforts; emissions have increased, mainly fueled by the rise in activity; modal shares have pulled away from public transport, with a decrease in bus and rail, towards an increase in car and air travel; energy intensities, though initially decreasing, are currently increasing; and fuel use has taken over 37% of Spanish final energy consumption. To target these issues the Spanish government has focused its efforts in targeting energy efficiency through dieselization, which has not led to positive results. More recently policies and measures have been directed towards redirecting modal shares and diversifying the fuel mix. Little has been done to reduce activity besides some anecdotic public awareness campaigns. Activity reduction may be achieved with regulations, restrictions and mobility plans; by increasing high speed rail and rail freight transport; by improving intermodality and tying the Spanish rail network with the EU; and with more urban transport planning at local level. - Highlights: → Complete analysis of recent trends in Spanish transport system from 1990 to 2008. → Passenger and freight activities have driven GHG emissions increase. → Modal shares have pulled away from public transport. → Policy efforts targeted energy efficiency and redirecting modal shares and diversifying the fuel mix. → Little has been done to reduce activity.

    1991-01-01

    This paper reports on the symmetrical rail accelerator that has four rails, which are arranged symmetrically around the bore. The opposite rails have the same polarity and the adjacent rails the opposite polarity. In this configuration the radial force acting upon the individual rails is significantly smaller than in a conventional 2-rail configuration and a plasma armature is focussed towards the axis of the barrel. Experimental results indicate a higher efficiency compared to a conventional rail accelerator

    In the XXI century transportation of goods plays a key role in the economy. Due to a good logistics the economy is able to grow fluently. Although land transportation is carried out mainly through trucks for the last several years there has been noted an increase in the percentage share of rail transport in the freight transport. The main goods transported by railways are mineral fuels, mining and quarrying products. They constitute the greater part of 70% of total transported goods. Transportation of material of such high weight, high hardness and with different shapes involves increased and accelerated wear and tear of the cargo space of the wagon. This process is also magnified by substances used to prevent overheating or goods theft. Usually they are in the form of chemical compounds powder, eg. Calcium. A very large impact on the wear of the freight wagons hull is made because of mechanical damage. Their source comes mostly from loading cargo with impetus and using heavy machines during unloading. A large number of cycles of loading and unloading during the working period causes abrasion of body and as a result after several years a wagon car qualifies for a major maintenance. Possibility of application composite panels in the process of renovating the wagons body could reduce the weight of whole train and prolong the service life between mandatory technical inspection. The Paper "Fatigue test of a fiberglass based composite panel. Increasing the lifetime of freight wagon" presents the research process and the results of the endurance test of the composite panel samples fixed to a metal plate. As a fixing method a stainless steel rivet nut and a stainless steel button head socket screws were chosen. Cyclic and multiple load were applied to test samples using a pneumatic cylinder. Such a methodology simulated the forces resulting from loading and unloading of the wagon and movement of the cargo during transport. In the study a dedicated stand equipped with a

    2017-01-01

    Full Text Available Damping based on the dry friction is frequently in suspensions of the freight wagons. The paper presents some aspects of vertical vibration of freight wagons. It uses a simple model considering that the vehicle was reduced to a mass suspended on a wheel, moving at constant speed on a rigid track with harmonic irregularity. Stick-slip vibration can occur due to the friction and it is characterized by sudden changes in the wheel acceleration affecting the ride quality. The paper shows the influence of stick-slip vibration on the wheel-rail dynamic force.

  8. Revisiting the reasons for contact fatigue defects in rails

    Directory of Open Access Journals (Sweden)

    Darenskiy Alexander

    2017-01-01

    Full Text Available As it is known rail is one of the most significant elements of the whole railway construction. Operation under alternating loads from wheels of the rolling stock and different ambient temperatures lead to appearance and development of rail defects and damages. A great variety of operational factors (freight traffic density, axial loads, traffic speeds, track layout and profile as well as special features of manufacturing and thermal treatment of rails create certain difficulties while identifying reasons for defects and damages. The article deals with an attempt to estimate influence of track layout and lateral forces on appearance of defects and damages in rails on the base of long-term observations of rail operation in Kharkiv Metro. On the basis of the vehicle/track mathematical model which considers structural features of both rolling stock and permanent way in underground systems, the level of lateral forces in curves was calculated. The coefficients of correlation between the track curvature, the level of forces and the amount of defected rails removed were later obtained, that made it possible to determine the dominant factor which may lead to appearance and development of contact fatigue defects in rails laid in curves.

  10. Mathematical model of optimal empty rail car distribution at railway transport nodes

    Directory of Open Access Journals (Sweden)

    Aleksandr RAKHMANGULOV

    2014-09-01

    Full Text Available At present there are two trends in the market of rail freight transportation in Russia: freight owners put forward higher demands to the transportation quality (promptness of delivery in an effort to reduce storage costs by means of reducing the size of freight shipment; the structure of railcar traffic volume of the railways of Russia is getting more complex due to the reduction of the average shipment size and due to the transfer of railcar fleet ownership to a large number of operating companies. These trends significantly complicate operational management supervision of railway stations and transport nodes. Application of typical data from the information system about the railcar location at the transportation node is not enough for the dispatchers to make the best decision concerning the car traffic management. The dispatcher traffic control service needs some software-based models of efficient railcar distribution. The article is concerned with the description and development of the mathematical model of empty railcar distribution for loading at the railway transport node; this model will take into account the requirements of railcar owners in terms of their cars application, the operating work level of railroad stations of the transportation node and the possibility of adding the groups of empty railcars to the transfer trains, clean-up trains and industrial railway trains operating on a tight schedule. The developed model and the software package were implemented in the information system of the industrial railway of the major metallurgical enterprise - OJSC «Magnitogorsk Metallurgical Works», which processes up to two thousand of railcars belonging to different owners. This model made it possible to reduce the labour intensity of dispatcher operation planning the empty railcar distribution for loading and reduce the total time the railcars spend in the enterprise railway system.

  19. The Energy-Efficient Operation Problem of a Freight Train Considering Long-Distance Steep Downhill Sections

    Directory of Open Access Journals (Sweden)

    Xuan Lin

    2017-06-01

    Full Text Available With the energy consumption rising in rail transport, the railway sector is showing increasing interest in the energy-efficient operation of freight trains. Freight trains require more complicated driving strategies than ordinary passenger trains do due to their heavy loads, especially in the long-distance steep downhill (LDSD sections that are very common in freight rail lines in China. This paper studies the energy-efficient operation of a freight train considering LDSD sections. An optimal control model including regenerative and pneumatic braking is developed for the freight train. Then, when a train leaves/enters the LDSD section, we verify the uniqueness of control transitions and discuss the speed profile linkage between LDSD and its adjacent sections, which indicates that the periodic braking should be applied on LDSD sections for optimality. Additionally, given the same running time for the entire journey, our analysis shows that electrical braking-full braking strategy is more energy-efficient than coasting-full braking strategy on LDSD sections. Finally, a numerical algorithm for the optimal driving solution is proposed. The simulation results demonstrate that the driving strategies generated by the proposed algorithm performs better than those from fuzzy predictive control and field operation regarding energy saving.

    2012-01-01

    'Safety culture' is identified in the literature as a critical element of healthy and safe workplaces. How can rail organizations ensure that consistently effective work health and safety cultures are maintained across the diversity of their operations? This paper reports on research that is currently underway in the Australian rail industry aimed at producing a Model of Best Practice in Safety Culture for the industry. Located in rail organizations dedicated to the mining industry as well as urban rail and national freight operations, the research examines the constructs of organizational culture that impact on the development and maintenance of healthy and safe workplaces. The research uses a multi-method approach incorporating quantitative (survey) and qualitative (focus groups, interviews and document analysis) methods along with a participative process to identify interventions to improve the organization and develop plans for their implementation. The research uses as its analytical framework the 10 Platinum Rules, from the findings of earlier research in the New South Wales (Australia) mining industry, Digging Deeper. Data collection is underway at the time of writing and preliminary findings are presented at this stage. The research method may be adapted for use as a form of organizational review of safety and health in organizational culture.

    2013-02-01

    Full Text Available Purpose. The railway transport plays an important role in social and economic life of the country and carries out the large containment of transportation activities. The transport industry should migrate towards innovation changes and increase its significance as an important transit subsystem on the way of renovation of both the infrastructure and the strategy of all transportation process components including the interaction with other transport modes. At present the life sets strategic challenges for the railway branch, and the basic goals among them are as follows: high-speed train traffic development, increase of the weight of freight trains, new rolling stock development etc. Due to the urgency of this subject, the researchers should cope with the task devoted to one of aspects of improving the freight transportation efficiency, namely to the study of effects of various factors and characteristics of technical conditions of the freight cars running gears (which are unavoidable to arise during operation on their basic dynamic indices. The deviations of technical conditions of running gears from the normal state of the wedge system of bogie swing suspension also play an important role among them. The purpose of the paper is to investigate the influence of different factors of the technical conditions of freight car running gears (size deviation in both the bearers and the wedge system during operation on their basic indices – coefficients of horizontal and vertical dynamics, vehicle body acceleration, frame strength, and derailment stability coefficient. Methodology. The study was conducted by numerical integration and mathematical modeling of the freight car dynamic loading using the software package “Dynamics of Rail Vehicles” (“DYNRAIL”. Findings. As a result of the research for freight car dynamic coefficients determination taking into account technical conditions of the side bearers, the dependencies of the basic freight cars

  6. ON OPERATION OF 740 M LONG FREIGHT TRAINS ON CZECH TEN-T RAILWAY NETWORK

    2016-09-01

    Full Text Available Regulation (EU No 1315/2013 defines actual scope of core and comprehensive TEN-T network, including both networks for railway freight transport. For the core network, possibility to operate 740 m long freight trains is required. The aim of this paper is to analyse availability of appropriate overtaking tracks for 740 m long freight trains. Due to ETCS braking curves and odometry, such trains, after ETCS implementation, will require 780-800 m long overtaking tracks. For practical reasons (e.g. bypass lines, whole Czech railway TEN-T network is analysed. The overtaking track, whose occupation means influence on scheduled traffic or threat to boarding passengers, are excluded. The data was collected from station schemes from Collection of Official Requisites for 2015/16 Timetable, issued by SŽDC, Czech state Infrastructure Manager. Most of appropriate tracks are over 800 m long, but their density in the network and in particular directions varies considerably. For freight traffic, gradient of the line is important, so in the resulting figure, there are marked significant peaks for particular lines as well. Czech TEN-T lines are further segmented on the basis of number of tracks and their traffic character. Then, specific issues on overtaking or crossing of 740 m long freight trains are discussed. As a conclusion, for long-term development of Czech TEN-T lines, targeted investment is recommended not only for passenger railway, but also for freight railway. An attractive capacity offer for railway undertakings, which can stimulate freight traffic on European Rail freight corridors, can be represented by network-bound periodic freight train paths with suitable long overtaking tracks outside bottlenecks. After the overtaking by passenger trains, a freight train should run without stop through large node station or a bottleneck area. Before the sections with high gradients, coupling of additional locomotives should be connected with the overtaking

    1990-01-01

    A model is developed to investigate possible effects of rail electrodynamics on the performance of railguns. This model describes the oscillatory nature of the rail motion in response to the Lorentz force and the compressive restoration force of material which is behind the rails. In this simple model the rails are found to oscillate with a frequency of β. The rail dynamic behavior induces local electric fields. The authors investigate the significance of these electric fields on stationary particles (lab frame) and on particles moving at the velocity of the plasma/projectile system (projectile frame)

  9. Plasma treatment of crane rails

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Crane operation results in wear and tear of rails and crane wheels. Renovation and efficiency of these details is therefore relevant. Modern technologies of wheels and rails restoration use surfacing or high-frequency currents treatment. Surface treatment with highly concentrated streams of energy- with a laser beam, plasma jet- is a promising direction.. It is proposed to increase the efficiency of crane rails by means of surface plasma treatment. The modes of treatment have been chosen.. Modelling of plasma jet thermal impact on a solid body of complex shape has been made. Plasma hardening regimes that meet the requirements of production have been defined. Structural transformation of the material in the crane rails on plasma treatment has been investigated. It has been concluded that for carbon and low alloy crane steels the plasma exposure zone is characterized by a high degree of hardened structure dispersion and higher hardness as compared to the hardness after high-frequency quenching. As this takes place phase transformations are both shift (in the upper zone of plasma influence and fluctuation (in the lower zone of the plasma. With high-speed plasma heating granular or lamellar pearlite mainly transforms into austenite. The level of service characteristics of hardened steel, which is achieved in this case is determined by the kinetics and completeness of pearlite → austenite transformation. For carbon and low alloy rail steels plasma hardening can replace bulk hardening, hardening by high-frequency currents, or surfacing. The modes for plasma treatment which make it possible to obtain a surface layer with a certain service characteristics have been defined

    A guided wave ultrasound system has been developed over the past 17 years to detect breaks in continuously welded rail track. Installation of the version 4 system on an 840 km long heavy duty freight line was conducted between January 2013 and June 2014. The system operates in pitch - catch mode with alternate transmit and receive transducers spaced approximately 1km apart. If the acoustic signal is not received at the receive station an alarm is triggered to indicate a break in the rail between the transmit station and the receive station. The system is permanently installed, powered by solar panels and issues broken rail alarms using the GSM network where available, and digital radio technology in other areas. A total of 931 stations were installed and the entire length of rail is interrogated every fifteen minutes. The system operates reliably although some problems involving unreliable GSM communication and theft of solar panels have been experienced. In the first two months of operation four broken rails were detected and train operation was halted temporarily for repairs.

  20. CargoCBM – Feature Generation and Classification for a Condition Monitoring System for Freight Wagons

    International Nuclear Information System (INIS)

    Gericke, C; Hecht, M

    2012-01-01

    Despite the fact that rail freight transport is one of the most environmentally friendly matters of transport, its growth has been far behind the growth of freight transport in general. Studies showed that a competitive disadvantage is caused by a low availability of rolling stock, especially freight wagons. Changing from a time based to a condition based maintenance strategy is believed to decrease down times by at least one third. To make condition based maintenance for freight wagons possible the TU Berlin and five industry partners started the research project CargoCBM. One task in this project is to develop algorithms for the automatic on-board diagnosis of wheel flats. The focus of the work is on the process of feature generation and feature selection as well as the application of different classifiers to automatically evaluate the data. Based on the results of measured data, features were selected and tested with different classifiers. Thought advanced classifiers such as neural networks have been analysed in accordance to their classification accuracy. It can be shown that with carefully constructed and selected features comparatively simple classifiers can lead to excellent results.

  1. Resisting momentum in the abutment to rotating of freight car bogie

    Directory of Open Access Journals (Sweden)

    Pavels GAVRILOVS

    2008-01-01

    Full Text Available On the Latvian railway, derailments of freight cars take place in the course of shunting work on marshalling yards. A number of factors during shunting work on marshalling yards may contribute to the derailments of rolling stock: longitudinal dynamics during braking of cars with the turned off brakes by locomotive, hauling down cars from a marshalling hill with braking position controlled by an operator, dry internal rails in curves, absence of greasing in the pivot unit of freight bogies. At present, measures allowing elimination of the car derailments during shunting work are developed.During the period between repairs, the abutment unit of freight car often works in conditions of dry friction. Our observations suggest that at the time of taking a car into repair, there is often an absence of greasing between trail bearing and center plate of the abutment, and a presence of sandy dust. It increases a friction and, together with high contact pressures and dynamic influence, hinders the turn of bogie at motion of car.In this paper, the results of studying the resisting moment in the abutment to turning of bogie is reported. The study was conducted on the basis of freight bogie of type 18-100; the body was leant on the center plate unit of the abutment, on the center plate unit, and on the sliders. Experiments were conducted, with the use of greasing and at the dry friction of center plate unit.

  2. Freight on a Low-Carbon Diet: Accessibility, Freightsheds, and Commodities.

    Taptich, Michael N; Horvath, Arpad

    2015-10-06

    The freight infrastructure network (e.g., roads, railways, waterways, etc.) is the backbone of nearly all trade partnerships in the United States and abroad. The manner in which the individual portions of its constituent parts are interrelated or arranged plays an important role for determining the environmental footprint of goods moved within the network. Herein, we compare the spatial distribution of potential consumer-producer exchanges (i.e., accessibility) under varying greenhouse gas (GHG) budgets or preferences for minimal transportation-related GHG emissions. We conduct case studies using two freight modes (truck and intermodal rail) for two representative commodities: meat/seafood and paper articles. Results across all counties in the United States indicate that the geographic area in which trade is possible, given a GHG budget, varies by transportation mode, location, and commodity. Our results suggest that intermodal terminal availability is an important determinant of low-GHG accessibility. Since only a fraction of road-to-rail terminals accommodate meat/seafood (4.9%) and paper (0.7%), the United States could increase its expected GHG savings associated with truck-to-rail mode-switching policies by 70% (+20 kg CO2,e/ton for meat/seafood) and 310% (+30 kg CO2,e/ton for paper) by upgrading current terminals to allow the exchange of all types of goods.

  3. ABOUT WAVEFORM OF BRAKING CYLINDER FILLING IN FREIGHT CARS

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Purpose. As part of the scientific paper it is necessary to study the waveform impact of the braking cylinders filling on longitudinal train dynamics at different modes of braking. At this one should estimate the level of maximum longitudinal forces and braking distance size in freight cars of various lengths. Methodology. In this paper we attempt to approximate the actual diagram of braking cylinders filling with rational functions of varying degrees. In selection of coefficients in the required functions the highest values of the longitudinal forces and braking distances were used as controlled parameters. They were compared with similar values obtained as a result of experimental rides. The level of longitudinal forces and braking distances amount were evaluated by means of mathematical modeling of train longitudinal vibrations, caused by different braking modes. Findings. At mathematical modeling was assumed that the train consists of 60 uniform four-axle gondola cars, weight of 80 tons, equipped with air dispenser No. 483 included in the median operation, composite braking blocks, and one locomotive VL-8. Train before braking has been pre-stretched. Various types of pneumatic braking (emergency, full service and adjusting braking of the freight train on the horizontal section of the track were simulated. As the calculation results were obtained values of the longitudinal forces, braking distances amounts and reduction time in speed at various braking modes. Originality. Waveform impact of the braking cylinders filling on the longitudinal forces level and braking distances amount in freight trains were investigated. Also the longitudinal loading of freight trains at various pneumatic braking was investigated. Practical value. Obtained results can be used to assess the level of largest longitudinal forces and braking distances in the freight trains of different lengths by mathematical modeling of different braking modes.

    A laboratory study was conducted with the aim of developing an as-rolled rail of over 100 ksi (689 N/mm 2 ) yield strength. A series of compositions providing both pearlitic and bainitic microstructures was evaluated. A fine pearlitic structure was developed in a 0.73 percent C -- 0.83 percent Mn -- 0.16 percent Si -- 0.75 percent Cr -- 0.21 percent Mo steel by simulating the mill cooling rate of 132-lb/yd (65.5-kg/m) rail. Two 100-ton commercial heats were made of this approximate composition and processed into 132-lb/yd (65.5-kg/m) rail. Samples tested in the laboratory ranged from 109 to 125 ksi (750 to 860 N/mm 2 ) in yield strength. The chromium-molybdenum rails also exhibited excellent fracture toughness and fatigue properties. Sections of the rail were joined by both flash-butt welding and thermite welding. The hardness peaks produced in the flash-butt welds could be reduced by applying either a postweld current or an induction heating cycle. The high-strength chromium-molybdenum rails have been in service for over eight months in curved sections of an ore railway that carries over 55 million gross long tons per year. 7 tables, 18 figs

  11. Life Cycle Assessment Comparing the Use of Jatropha Biodiesel in the Indian Road and Rail Sectors

    Energy Technology Data Exchange (ETDEWEB)

    Whitaker, M.; Heath, G.

    2010-05-01

    This life cycle assessment of Jatropha biodiesel production and use evaluates the net greenhouse gas (GHG) emission (not considering land-use change), net energy value (NEV), and net petroleum consumption impacts of substituting Jatropha biodiesel for conventional petroleum diesel in India. Several blends of biodiesel with petroleum diesel are evaluated for the rail freight, rail passenger, road freight, and road-passenger transport sectors that currently rely heavily on petroleum diesel. For the base case, Jatropha cultivation, processing, and use conditions that were analyzed, the use of B20 results in a net reduction in GHG emissions and petroleum consumption of 14% and 17%, respectively, and a NEV increase of 58% compared with the use of 100% petroleum diesel. While the road-passenger transport sector provides the greatest sustainability benefits per 1000 gross tonne kilometers, the road freight sector eventually provides the greatest absolute benefits owing to substantially higher projected utilization by year 2020. Nevertheless, introduction of biodiesel to the rail sector might present the fewest logistic and capital expenditure challenges in the near term. Sensitivity analyses confirmed that the sustainability benefits are maintained under multiple plausible cultivation, processing, and distribution scenarios. However, the sustainability of any individual Jatropha plantation will depend on site-specific conditions.

    Full Text Available The objectives of this research are to develop the variables which moderate the relationship between commitment and transportation services and to analyze the moderating effects of the variables. The conceptual and operational definitions of the variables were ascertained from prior research. The reliability and validity of collected data were tested by various methods and hypotheses are tested by a moderated regression analysis. The results are as follows. First, the moderating variables on the relationship between commitment and transportation services are identified as internal orientation and market orientation. The former has three sub-dimensions such as collaboration between departments, work standardization and process improving and the latter has three sub-dimensions such as intelligence generation, intelligence dissemination, and responsiveness. Second, work standardization is ascertained to enhance the relationship between commitment and trust. Third, process improving is verified as enhancing the relationship between commitment and trust. Fourth, work standardization is ascertained to enhance the relationship between commitment and flexibility. Fifth, intelligence generation is identified as enhancing the relationship between commitment and trust. Sixth, intelligence generation is verified as enhancing the relationship between commitment and flexibility. Therefore, forwarders can supply superior transportation services for customers when they achieve commitment and orientation such as work standardization, improvement of their service processes, and activities concerned with intelligence generation.

  13. Bronze railing from Mediana

    2003-01-01

    Full Text Available The hoard containing components of bronze railing was discovered in trench 7 during excavations at Mediana in 2000. Railing consists of cancelli and herms with busts of deities between them. Railing was constructed in such a way that it was possible to disassemble and reassemble it. Three cancelli one fragmented semicancellus cast together with herm and herms, one with bust of Aesculapius and other with bust of Luna. It could be concluded that railing consisted of two segments with passage between them. Male deities were represented on the left segment of the railing and female deities on the right segment. Detailed analysis revealed that Aesculapius as well as Luna bear strong mark of classical Greek and Hellenistic art, which experienced some kind of renaissance in the time of Constantine I. It is very probable that we can recognize the portrait of Faustina, Constantine’s wife in the portrait of Luna. According to the historical events the railing could have been produced before 325 AD when Constantine definitively accepted Christianity at Council of Nicaea. It is difficult to say where the railing had been produced. It had been most probably brought to Mediana during the stay of emperor Julian in Niš in 361. The sculptures found in one room of the villa with peristyle had probably been brought at the same time. The apse of triclinium of this villa had most likely been arranged as small shrine with bronze railing at its entrance. The railing was buried in 378 after battle of Adrianople and invasion of Goths in diocese Dacia.

The study aims to clarify the existing method of determining the factor of stability from the tire longitudinal forces to ensure the sustainability of cars with increasing speeds of the rolling stock. Methodology. Research was conducted by the method of mathematical modeling of loading freight car when driving at different speeds on straight and curved track sections. Findings. Analysis of the results shows that, for all selected freight cars for the calculation, the value of the safety factor by squeezing is smaller than the formulas of Standards. Corrections made to the formula for determining the safety factor by squeezing longitudinal forces, would achieve: 1 a higher safety factor of lightweight cars, excluding them squeezing longitudinal forces in the entire range of speeds of freight trains; 2 to develop and implement measures to prevent squeezing of cars in the entire range of motion; 3 to determine the degree of stability of the empty car in the head, middle and tail laden trains; 4 to offer optimal scheme of mixed trains formation.

    Kaewunruen, S.; Ishida, M.

    2014-01-01

    Rail squats and studs are typically classified as the propagation of any cracks .that have grown longitudinally through the subsurface. Some of the cracks could propagate to the bottom of rails transversely, which have branched from the initial longitudinal cracks with a depression of rail surface. The rail defects are commonly referred to as 'squats' when they were initiated from a damage layer caused by rolling contact fatigue, and as 'studs' when they were associated with a white etching layer caused by the transformation from pearlitic steel due to friction heat generated by wheel sliding or excessive traction. Such above-mentioned rail defects have been often observed in railway tracks catered for either light passenger or heavy freight traffics and for low, medium or high speed trains all over the world for over 60 years except some places such as sharp curves where large wear takes place under severe friction between the wheel flange and rail gauge face. It becomes a much-more significant issue when the crack grows and sometimes flakes off the rail (by itself or by insufficient rail grinding), resulting in a rail surface irregularity. Such rail surface defects induce wheel/rail impact and large amplitude vibration of track structure and poor ride quality. In Australia, Europe, and Japan, rail squats/studs have occasionally turned into broken rails. The root cause and preventive solution to this defect are still under investigation from the fracture mechanics and material sciences point of view. Some patterns of squat/stud development related to both curve and tangent track geometries have been observed and squat growth has been monitored for individual squats using ultrasonic mapping techniques. This paper highlights the field monitoring of squat/stud distribution and its growth. Squat/stud growth has been detected and scanned using the ultrasonic measurement device on a grid applied to the rail surface. The depths of crack paths at each grid node form a

Some patterns of squat/stud development related to both curve and tangent track geometries have been observed and squat growth has been monitored for individual squats using ultrasonic mapping techniques. This paper highlights the field monitoring of squat/stud distribution and its growth. Squat/stud growth has been detected and scanned using the ultrasonic measurement device on a grid applied to the rail surface. The depths of crack paths at each

    2016-07-01

    The topic of freight transport by rail is a complex theme and, in recent years, a main issue of European policy. The legislation evolution and the White Paper 2011 have demonstrated the European intention to re-launch this sector. The challenge is to promote the intermodal transport system to the detriment of road freight transport. In this context intermodal freight terminals, play a primary role for the supply chain, they are the connection point between the various transport nodes and the nodal points where the freight are handled, stored and transferred between different modes to final customer. To achieve the purpose, it is strengthen the improvement of existing intermodal freight terminals and the development of innovative intermodal freight terminals towards higher performance (ERRAC, 2012). Many terminal performances improvements have been proposed and sometime experimented. They are normally basing on combinations of operational measures and innovative technologies (e.g. automatic horizontal and parallel storage and handling, automated gate and sensors for tracking systems data exchange) tested in various terminals, with often-contradictory results. The research work described in this paper (developed within the Capacity4Rail EU project) focusses on the assessment of effects that these innovations can have in the intermodal freight terminals combined in various alternative consistent effective scenarios. The methodological framework setup to assess these innovations is basing on a combination of analytical methods based on sequential algorithms and discrete events simulation models. The output of this assessment method are key performance indicators (KPIs) selected according to terminals typologies and related to different aspects (e.g. management, operation and organization). The present paper illustrates the application of the methodological framework, tuned on the operation of various intermodal terminals, for the validation on today operation and the

    Nikas, Dimitrios; Meyer, Knut Andreas; Ahlström, Johan

    2017-07-01

    Pearlitic steels are commonly used for railway rails because they combine good strength and wear properties. During service, the passage of trains results in a large accumulation of shear strains in the surface layer of the rail, leading to crack initiation. Knowledge of the material properties in this region is therefore important for fatigue life prediction. As the strain is limited to a thin surface layer, very large strain gradients can be found. This makes it very difficult to quantify changes in material behavior. In this study hardness measurements were performed close to the surface using the Knoop hardness test method. The orientation of the pearlitic lamellas was measured to give an overview of the deformed microstructure in the surface of the rail. Microstructural characterization of the material was done by optical microscopy and scanning electron microscopy to evaluate the changes in the microstructure due to the large deformation. A strong gradient can be observed in the top 50 μm of the rail, while deeper into the rail the microstructure of the base material is preserved.

    2016-01-01

    Full Text Available Transportation is one of the major energy consumption and carbon emission industries. Railway transport is a typical low-carbon transport. To accelerate the green low-carbon transportation development and improve the railway market share, this paper defines the concept of carbon saving profit to study the price of railway freight after the government functions were separated from railway enterprise management. First, taking full account of market factors and on the principle of utility maximization and maximum likelihood method, the sharing ratio model of transportation modes is established. Then consideration is given to both the profit of railway enterprises and social benefits, and income maximization model of railway freight based on low-carbon economy is established. The model can scientifically guide the transportation users who prefer to use resource-saving and environmental-friendly transportation modes, optimize transportation structure, and comprehensively improve the efficiency of transportation system. Finally, case analysis is conducted to verify the rationality and validity of the model, and reference for the rail freight pricing is provided.

    Truck, rail, water, air, and pipeline modes each serve a distinct share of the freight transportation market. The current allocation of freight by mode is the product of technologic, economic, and regulatory frameworks, and a variety of factors -- price, speed, reliability, accessibility, visibility, security, and safety -- influence mode. Based on a comprehensive literature review, this report considers how analytical methods can be used to project future modal shares and offers insights on federal policy decisions with the potential to prompt shifts to energy-efficient, low-emission modes. There are substantial opportunities to reduce the energy used for freight transportation, but it will be difficult to shift large volumes from one mode to another without imposing considerable additional costs on businesses and consumers. This report explores federal government actions that could help trigger the shifts in modal shares needed to reduce energy consumption and emissions. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

    Many communities in the United States have been adding new light rail to bus-predominant public transit systems. However, there is disagreement as to whether opening light rail lines attracts new ridership or merely draws ridership from existing transit users. We study a new light rail line in Salt Lake City, Utah, USA, which is part of a complete street redevelopment. We utilize a pre-test post-test control group quasi-experimental design to test two different measures of ridership change. The first measure is calculated from stops along the light rail route; the second assumes that nearby bus stops might be displaced by the rail and calculates ridership change with those stops included as baseline. Both the simple measure (transit use changes on the complete street light rail corridor) and the "displacement" measure (transit use changes in the one-quarter mile catchment areas around new light rail stops) showed significant ( p rail bus users. In particular, the displacement analysis discredits a common challenge that when a new light rail line opens, most passengers are simply former bus riders whose routes were canceled in favor of light rail. The study suggests that light rail services can attract additional ridership to public transit systems. In addition, although pre-post control-group designs require time and effort, this project underscores the benefits of such quasi-experimental designs in terms of the strength of the inferences that can be drawn about the impacts of new transit infrastructure and services.

    Full Text Available Ruby on Rails (“Rails” is the dominant web programming framework for Ruby and, even outside the Ruby community, is considered the epitome of the latest generation of high-productivity, open source web development tools. Django is one of many competing web development frameworks for Python. It is notable, first, for being highly regarded amongst Python programmers, and second, for being one of the few of the new generation of framework that does not ape Ruby on Rails. Both Rails and Django claim greatly enhanced productivity, compared with more traditional web development frameworks. In this paper, we compare the two frameworks from the point of view of a developer attempting to choose one of the two frameworks for a new project.

    2012-01-01

    Full Text Available The article analyses the current traction rolling-stock used by „Lietuvos geležinkeliai“ Plc. for freight transportation. The technical data of the above mentioned rolling-stock is explored and compared, and operation costs are estimated in the article. After the assessment of the forecasts of freight flows on the constructed railway „Rail Baltica“, the algorithm for selection of freight locomotives was proposed. The efficiency of the locomotives operated on the railway is determined by three multicriteria evaluation methods: the sum of ratings, simple additive weighting, and the geometric mean method. Locomotives are valued in accordance with technical, economic and ecological parameters. The results of possible effective performance of the rolling stock have been determined by changing coefficient values of the criteria. Finally, basic conclusions are given.

  4. DETERMINATION OF OBJECTIVES FOR URBAN FREIGHT POLICY

    2014-12-01

    Full Text Available Background: Decisions regarding strategic planning of urban freight transport very often are based on superficial assumptions inadequately reflecting the actual character of encountered challenges. The trend may be observed to adapt isolated solutions without supporting measures and verification of expected outcomes. Selected urban freight solutions have a significant potential to alleviate transport related problems, but they require unorthodox approach beyond standard traffic planning and road management. City's current planning experience must be taken into account to plan an optimized sequence of actions. Method: Due to complexity of the problem and specific decision making factors the analytic network process ANP was selected to determine relevant objective of the urban freight policy. Gdynia was selected as the subject for modeling with a review of the current freight planning practice as a first step. Then, classification of policy objective and their prerequisites were identified supported with descriptive feasibility assessment. This allowed for a development of the ANP decision-making model. Results: Considered objectives for urban freight policy were identified were optimization, reduction and transfer. After verifying relevant decision factors optimization was selected as the most feasible option for Gdynia. Other alternatives were rated around four times lower with a slight prevalence of reduction over transfer. Such ranking reflects current planning practice and availability of transferable experiences. Despite the indicative results, it must be stressed that urban freight planning should be based on the long term methodical approach not to exclude any emerging possibilities.

    2011-08-01

    Traditionally, freight transport and telematics solutions that exploit the GPS capabilities of in- vehicle devices to provide innovative Location Based Services (LBS) including track and trace transport systems have been the preserve of a select cluster of transport operators and organisations with the financial resources to develop the requisite custom software and hardware on which they are deployed. The average cost of outfitting a typical transport vehicle or truck with the latest Intelligent Transport System (ITS) increases the cost of the vehicle by anything from a couple to several thousand Euros, depending on the complexity and completeness of the solution. Though this does not generally deter large fleet transport owners since they typically get Return on Investment (ROI) based on economies of scale, it presents a barrier for the smaller independent entities that constitute the majority of freight transport operators [1].The North Sea Freight Intelligent Transport Solution (NS FRITS), a project co-funded by the European Commission Interreg IVB North Sea Region Programme, aims to make acquisition of such transport solutions easier for those organisations that cannot afford the expensive, bespoke systems used by their larger competitors.The project addresses transport security threats by developing a system capable of informing major actors along the freight logistics supply chain, of changing circumstances within the region's major transport corridors and between transport modes. The project also addresses issues of freight volumes, inter-modality, congestion and eco-mobility [2].

With the advent of new designs of freright cars the task of designing the more modern bogies, assessment of their dynamic properties depending on the type and structure of pecularities, accounting the axle loadings, providing the dynamic and running characteristics, meeting the conditions of impact on the track, stability, and frame forces intensity etc. becomes especially important. In order to launch the new production into manufacture and to assess the dynamic properties using different designs of bogies the running testes were conducted. They allowed one to compare the dynamic performance of the new bogie with the existing models. Methodology. The study was conducted using the method of numerical integration and mathematical modeling of dynamic loading of freight cars using the software package «Dynamics of Rail Vehicles» («DYNRAIL». Findings. The results of studies of dynamic characteristics of open cars with new and worn wheels of bogie models 18-9771, 18-9770 and 18-578 in graphical and tabular form are presented. All figures are within the normative values and do not exceed the maximum admissible ones. Originality. When designing the bogie for loading 23.5 t/axle almost all available technical solutions to improve the characteristics of the freight car bogies (elastic bearers, cassette bearing in axle boxes, axle boxe adapter of original design, bilinear central spring suspension, etc. were used. Practical value. As a result of the engineering works on projecting and manufacturing of the improved designs of freight car bogies a new design was received. It is highly competitive with the dynamic qualities of the best ones. Made choice of rational values of elastic-dissipative parameters of the bogie allows one to create standard series of running gears for freight cars for promising operating conditions.The results are of practical importance.

  12. To the question of modeling of wheels and rails wear processes

    Directory of Open Access Journals (Sweden)

    S.V. Myamlin

    2013-06-01

    Full Text Available Purpose. There is a need of wear process modeling in the wheel-rail system. This is related to the fact that the wear processes in this system are absolutely different in the initial and final stages. The profile change of rail and, especially, of the wheels caused by the wear significantly affects the rolling stock dynamics, traffic safety and the resource of the wheels and rails. Wear modeling and the traffic safety evaluation requires the accounting of the low frequency component forces (including the modeling of transitional areas affecting the wheel on the side of the rail and carriage in motion of rolling stock, so the statistical analysis is not possible. Methodology. The method of mathematical modeling of the wheel set and the rail interaction was used during the research conducting. Findings. As a result of the modeling of the wheel set motion on the rail track, the mathematic model with 19 freedom degrees was obtained. This model takes into account the axle torque and studies wheels constructions as the components of the mechanical systems, consisting of a hub and tire. Originality. The mathematic model allows evaluating the wear degree of the wheels and rails when using on the rolling stock not only all-metal wheel sets, but also compound ones with the use of spring wheels and independent rotation of semi-axes with the wheels. Practical value. The development of the improved mathematical model of freight car wheel set motion with differential rotation of the wheels and compound axles allows studying the wear processes of wheels and rails.

  13. Applying the polluter-pays principle to rail: Environmental differentiation of rail access charges

    Energy Technology Data Exchange (ETDEWEB)

    Pons-Rigat, A.; Turro Calvet, M.; Ubalde Claver, Ll.

    2016-07-01

    Environmental charges to rail service operators are still at an early stage of implementation in Europe. Current schemes are dissimilar and most of them have a very limited scope or do not provide effective incentives to abate environmental impacts. This is due to several practical difficulties in implementing internalisation pricing schemes in the railway sector. The first difficulty arises from the lack of internalisation in other transport modes and the small competitive margin of railways. Increasing the overall level of rail charges could affect their survival. A second difficulty is due to the uncertainties in the valuation of external costs and in the establishment of the optimal level of charges. On top of that, the imperfect competition in the rail market and its operational and financial rigidities imply that pricing decisions could be unfair and produce undesired demand effects. These difficulties should not prevent, however, advancing towards the application to rail of adequate charging methods for its environmental costs. This paper addresses the problem of setting environmentally differentiated rail charges through an analytical approach. A generalised formulation is developed that sets the level of charges as a function of the degree of internalisation in other modes. Then, the optimal trade-off in the level of differentiation is assessed to extract general guidelines. Based on this, both the derived overall costs and benefits and the impacts on each agent are quantified. (Author)

    Railway has emerged as a fast, convenient, safe, clean, and low-cost alternative to air and road transportation. Many countries have invested in rail transportation. In America, Europe and Asia, large investments are planned for rail transportation. This is because congestion problems can be reduced with the introduction of rail transportation. Rail transportation involves several components which are important to ensure the smooth and safe delivery of services such as locomotives, rail stations and railway tracks. Rail transit stations are places where trains stop to pick-up and drop-off passengers. Stations are vital for many to enable them to engage in work and social commitments. This paper focuses only on the rail transit station as it is one of the important components in rail transportation. It is also considered as a key public meeting place and space for interactions in a community. The role of rail transit station and the requirements of a good rail transit station are also described in this paper. Steps in selecting the location of rail transit station include the function and facilities in rail transit station are discussed with reference to best practices and handbooks. Selection of the appropriate rail transit station locations may help users indirectly. In addition, this paper will also elucidate on the design considerations for an efficient and effective rail transit station. Design selections for the rail transit station must be balanced between aesthetic value and functional efficiency. The right design selection may help conserve energy, assure and facilitate consumers even thought a rail transit station plays a smaller role in attracting consumers compared to a shopping complex or a residential building. This will contribute towards better and greener building for a green transportation facility. Thus, with this paper it is expected to assist the relevant authority to identify important elements in the selection and determination of suitable

    Full Text Available South Africa has two major rail operators that constitute the rail transport industry. These are Transnet Freight Rail (TFR, which operates freight and the Passenger Rail Agency of South Africa (PRASA. Although the Railway Safety Regulator (2011:29 reported the year on year declining trend of collisions, the main concern is that the costs incurred for each year’s incidents is escalating. This article is concerned with the declining safety standards of these operators as evidenced by 742 collisions recorded during the 2011/2012 financial year for both operators. The focus is mainly on collisions during the movement of rolling stock within the PRASA environment. The analysis of the occurrences is narrowed down, with the emphasis on the province of Gauteng. In the analysis of the causes of these collisions, the problems that led to the root causes of these collisions is reported. Of critical importance is that every transport operator is faced with the challenges of how to effectively respond to the basic transport needs and requirements of the travelling public. The transport users’ need is to travel between the two geographical points. During the journey between these geographical points, the operator has safety and security requirements and must provide a reliable, accessible and affordable transport system. As the travelling public becomes more affluent, the transport needs become open ended and require much more rational public choices. The rail transport system remains a vital or indispensable business sector of the economy. By investing in new technology, rolling stock and infrastructure, we woud see an increase in innovation, competitiveness, and an elevated standard of living.

Intermodal freight forecasting plays an important role in ports management and in the planning of the principal port activities. Hence, the study is carried out under the motivation of knowing that modeling the freight transport flows could facilitate the management of the infrastructure and optimize the resources of the ports facilities. The use of advanced models for freight forecasting is essential to improve the port level-service and competitiveness. In this paper, two forecasting-models are presented and compared to predict the freight volume. The models developed and tested are based on Artificial Neural Networks and Support Vector Machines. Both techniques are based in a historical data and these methods forecast the daily weight of the freight with one week in advance. The performance of the models is evaluated on real data from Ro-Ro freight transport in the Port of Algeciras Bay. This work proposes and compares different approaches to determine the best prediction. In order to select the best model a multicomparison procedure is developed using several statistical test. The results of the assessed models show a promising tool to predict Ro-Ro transport flows with accuracy. (Author)

    Highlights: • An insightful overview of energy usage in urban rail systems is given. • The principal measures to reduce urban rail energy consumption are appraised. • A methodology is proposed to help implement energy saving schemes in urban rail. • Regenerative braking is shown to offer the greatest energy saving potential. - Abstract: There is increasing interest in the potential of urban rail to reduce the impact of metropolitan transportation due to its high capacity, reliability and absence of local emissions. However, in a context characterised by increasing capacity demands and rising energy costs, and where other transport modes are considerably improving their environmental performance, urban rail must minimise its energy use without affecting its service quality. Urban rail energy consumption is defined by a wide range of interdependent factors; therefore, a system wide perspective is required, rather than focusing on energy savings at subsystem level. This paper contributes to the current literature by proposing an holistic approach to reduce the overall energy consumption of urban rail. Firstly, a general description of this transport mode is given, which includes an assessment of its typical energy breakdown. Secondly, a comprehensive appraisal of the main practices, strategies and technologies currently available to minimise its energy use is provided. These comprise: regenerative braking, energy-efficient driving, traction losses reduction, comfort functions optimisation, energy metering, smart power management and renewable energy micro-generation. Finally, a clear, logical methodology is described to optimally define and implement energy saving schemes in urban rail systems. This includes general guidelines for a qualitative assessment and comparison of measures alongside a discussion on the principal interdependences between them. As a hypothetical example of application, the paper concludes that the energy consumption in existing urban

  6. Rail transport systems approach

    CERN Document Server

    2017-01-01

    This book shows how the systems approach is employed by scientists in various countries to solve specific problems concerning railway transport. In particular, the book describes the experiences of scientists from Romania, Germany, the Czech Republic, the UK, Russia, Ukraine, Lithuania and Poland. For many of these countries there is a problem with the historical differences between the railways. In particular, there are railways with different rail gauges, with different signaling and communication systems, with different energy supplies and, finally, with different political systems, which are reflected in the different approaches to the management of railway economies. The book’s content is divided into two main parts, the first of which provides a systematic analysis of individual means of providing and maintaining rail transport. In turn, the second part addresses infrastructure and management development, with particular attention to security issues. Though primarily written for professionals involved...

    Superconducting augmentation consists of a superconducting coil operating in the persistent mode closely coupled magnetically with a normally conducting rail gun. A theoretical investigation of the effect of this system on a rail gun has shown that two benefits occur. Projectile velocities and launch efficiencies increase significantly depending on the magnetic coupling between the rail and augmentation circuits. Previous work evaluated an idealized system by neglecting energy dissipation effects. In this paper, the authors extend the analysis to include the neglected terms and show improved actual launch efficiencies for the SARG configuration. In this paper, the authors discuss details of projectile design in depth and present preliminary results of rail gun performance

  9. Study on Rail Profile Optimization Based on the Nonlinear Relationship between Profile and Wear Rate

    2017-01-01

    Full Text Available This paper proposes a rail profile optimization method that takes account of wear rate within design cycle so as to minimize rail wear at the curve in heavy haul railway and extend the service life of rail. Taking rail wear rate as the object function, the vertical coordinate of rail profile at range optimization as independent variable, and the geometric characteristics and grinding depth of rail profile as constraint conditions, the support vector machine regression theory was used to fit the nonlinear relationship between rail profile and its wear rate. Then, the profile optimization model was built. Based on the optimization principle of genetic algorithm, the profile optimization model was solved to achieve the optimal rail profile. A multibody dynamics model was used to check the dynamic performance of carriage running on optimal rail profile. The result showed that the average relative error of support vector machine regression model remained less than 10% after a number of training processes. The dynamic performance of carriage running on optimized rail profile met the requirements on safety index and stability. The wear rate of optimized profile was lower than that of standard profile by 5.8%; the allowable carrying gross weight increased by 12.7%.

  11. A REVIEW OF HIGH-SPEED RAIL PLAN IN JAVA ISLAND: A COMPARISON WITH EXISTING MODES OF TRANSPORT

    Directory of Open Access Journals (Sweden)

    Eko Hartono

    2013-05-01

    It can be concluded that journey time and fare of the high-speed rail is very competitive to the air transport in Jakarta-Surabaya corridor. The journey time to travel from Jakarta to Surabaya is 4 hours and 19 minutes by high-speed train and 4 hours and 40 minutes by air. Based on the benchmarking analysis, the suitable fare for the high-speed rail should be 70% of the air transport. This study predicted that 61% of air passenger, 18% of conventional rail passenger and 12% of bus passenger will switch to the high-speed rail service in 2020. In total, the high-speed rail will have 24% of market share for the passenger transport and becomes the second largest market share after road transport (52%. The conventional rail and air transport have 14% and 9% of total market share to travel from Jakarta to Surabaya and vice versa. The high-speed rail development reduces carbon emissions caused by transportation systems in Java Island. It has been calculated that there are 2.542 million tonnages of CO2 per annum without introducing high-speed rail, however, the CO2 emissions decrease to 1.694 million tonnages per annum if the high-speed rail is developed in Java Island. Generalized cost of the high-speed rail is higher than road and conventional rail. However, it is lower than air transport. Keywords: Java high-speed rail, HSR Comparison, modal share, journey time

  17. Evaluation of life-cycle air emission factors of freight transportation.

    2007-10-15

    Life-cycle air emission factors associated with road, rail, and air transportation of freight in the United States are analyzed. All life-cycle phases of vehicles, infrastructure, and fuels are accounted for in a hybrid life-cycle assessment (LCA). It includes not only fuel combustion, but also emissions from vehicle manufacturing, maintenance, and end of life, infrastructure construction, operation, maintenance, and end of life, and petroleum exploration, refining, and fuel distribution. Results indicate that total life-cycle emissions of freight transportation modes are underestimated if only tailpipe emissions are accounted for. In the case of CO2 and NOx, tailpipe emissions underestimate total emissions by up to 38%, depending on the mode. Total life-cycle emissions of CO and SO2 are up to seven times higher than tailpipe emissions. Sensitivity analysis considers the effects of vehicle type, geography, and mode efficiency on the final results. Policy implications of this analysis are also discussed. For example, while it is widely assumed that currently proposed regulations will result in substantial reductions in emissions, we find that this is true for NOx, emissions, because fuel combustion is the main cause, and to a lesser extent for SO2, but not for PM10 emissions, which are significantly affected by the other life-cycle phases.

    2008-01-01

    Considering the externalities of freight transport activity (energy use, accidents, congestion, its related GHG emissions, and lost oil revenues) this article reviews trends from 1990-2005 in truck freight fuel intensity (energy use per tonne-km moved), on road truck fuel economy (L/ 100 km driven......). We review changes in decoupling truck freight activity from GDP. We examine separately five manufacturing sectors using data from Statistics Denmark on vehicle performance for 1980-2006. Our four major findings are: (1) truck freight energy intensity (mj/tonne-km) continues to grow as well as CO2...... emissions; (2) decoupling has not been large enough to reduce overall energy use of truck; (3) because of the absence of fuel economy regulations, a low average vehicle load, increased hauling distance, overall energy use of truck freight will continue to expand; (4) results show that standard freight...

    Full Text Available Purpose. The purpose of this paper is to analyze the results of theoretical and experimental studies of the strength properties of rolling stock; search for design tools, modeling, selection, justification of the service life extension of freight cars and their elements. Methodology. The article is based on the finite element method (FEM. It makes possible to completely automate the calculation of mechanical systems, although, as a rule, it requires a much larger number of computational operations than the classical methods of mechanics. The modern level of development of computer technology opens wide opportunities for the introduction of FEM into engineering practice. FEM is implemented in many well-known and widely distributed software products that provide strength analysis of models of machines, mechanisms, structures, including the rolling stock of railways. Findings. The article presents an analysis of the theoretical and experimental studies of the strength properties of rolling stock elements on the example of the spine beam of freight cars; calculations were performed using a modern application program package. The presented example of use of the offered approach has shown its operation capacity and efficiency, as well as correctness of the research direction. The offered approach can be used when solving similar optimization tasks in research and developmental practice of transport mechanical engineering. Originality. The authors proposed me-thod of determining the reliability indicators and solving scientific and applied problem of calculating the elements of freight cars, taking into account the operation features and the loading mode impact. This allows determining their durability at the design stage. There were developed and investigated the models of the spine beam of a freight car, on the basis of which the dependences characterizing the stress-strain state of its elements were obtained.

  8. Defining freight rates as a contribution to the successful operation of container shipping companies

    Directory of Open Access Journals (Sweden)

    Renato Oblak

    2016-12-01

    Full Text Available The globalization of the world market and the flexibility of containerization to adjust to the constant changes in supply and demand of the international goods market, has led to a continuous increase in the portion of the container transport within the international maritime cargo transport. By the increase of the container transport level, the impact and importance of container freight rates have been growing, the variability of which directly reflects on the world economy. The aim of this paper is to analyze the efficiency of actual methods in establishing the container freight rates according to the problems which appear in the container shipping operation and refer to large differences in the weights of the actual transported cargo and the declared cargo in containers. The consequence of is lower freight rates and higher costs of the vessels exploitation, concerning the increase of the bunker oil consumption. The conducted research is based on actual data that have been collected and analyzed from particular container vessel liner services within period of 90 days and casting off from 16 container ports. The proposed measures could increase the level of usability of the transporting ships capacities and enable a more accurate and correct account of sea freight rates. The results of the research have shown that by increasing the control of accuracy of the cargo weight in containers and by improving the model of accounting, the freight rates can increase the incomes of shipping companies maintaining the same level of container traffic, which can have a direct influence on the efficiency of their successful operation.

  12. Finite element analysis of rail-wheel interaction

    International Nuclear Information System (INIS)

    Rahman, F.; Kharlamov, Y.A.; Islam, S.; Khan, A.A.

    2006-01-01

    Damage mechanisms such as surface cracks, plastic deformation and wear can significantly reduce the service life of railway track and rolling stock. They also have a negative impact on the rolling noise as well as: on the riding comfort. A proper understanding of these mechanisms requires a detailed knowledge of physical interaction between wheel and rail. Furthermore, demands for higher train speeds and increased axle loads implies that the consequences of larger contact. forces between wheel and rail must be thoroughly investigated. Two methods have traditionally been used to investigate the rail-wheel contact, that is the Hertz analytical method and simplified numerical method based on the boundary element (BE) method. These methods rely on a half-space assumption and a linear material model. This paper presents that to overcome these limitations, a tool for FE-based quasistatic wheel-rail contact simulations has been developed. The tool is a library of ANSYS macro routines for configuring, meshing and loading of a parametric wheel-rail model. The meshing is based on measured wheel and rail profiles. The wheel and rail materials in the contact region are treated as elastic-plastic with kinematic hardening. By controlling the values of the configuration parameters, representations of various driving cases can be generated. The quasi-static loads are obtained from train motion. Interaction phenomena such as rolling, spinning and sidling can be included. The modeling tool and a methodology are described in the presented paper. Significant differences in the calculated state between the FE solution and the traditional approaches can be observed. These differences are most significant in situations with flange contact.

    1976-07-01

    In order to determine the feasibility of pipeline as an intercity freight transportation mode, it was necessary to examine its technological feasibility and reliability. This report describes the technology of the major generic freight pipelines in terms of both historical and current trends and operations. Additionally, it presents a state-of-the-art review of calculating energy requirements of various generic freight pipelines. It was concluded that slurry and pneumatic pipelines are technologically feasible and reliable. There are many commercial installations of both types operating around the world. Based on European experience with pneumo-capsule pipelines for mail delivery and Russian gravel- and sand-transport installations, it appears that a pneumo-capsule pipeline is a technologically feasible and operationally reliable mode for transport of solids. Since no commercial pneumo-capsule pipeline installations yet exist in the U.S., it seems desirable that a service demonstration of the advantages and feasibility of this mode of transport be undertaken to attract the shippers' confidence. Hydro-capsule pipelines are technologically feasible, but its reliability within a commercial environment remains to be tested.

    1990-01-01

    The high resolution neutron diffraction technique has been applied to determine, non-destructively, the residual stress distribution developed in the head of a railway rail after normal service. Measurements were made, using the neutron strain scanner at the Institute Laue Langevin, Grenoble, on a transverse slice of rail 12mm thick taken from a section of straight track. The rail head was scanned in the three principal orientations in a series of parallel traverses sufficiently close to enable a two-dimensional matrix of data to be accumulated and vertical, transverse and longitudinal residual stress contours to be drawn. The results demonstrate the effectiveness and unique characteristics of the neutron technique to determine nondestructively and continuously the residual stresses inside engineering components

  20. Detection method based on Kalman filter for high speed rail defect AE signal on wheel-rail rolling rig

    Science.gov (United States)

    Hao, Qiushi; Shen, Yi; Wang, Yan; Zhang, Xin

    2018-01-01

    Nondestructive test (NDT) of rails has been carried out intermittently in traditional approaches, which highly restricts the detection efficiency under rapid development of high speed railway nowadays. It is necessary to put forward a dynamic rail defect detection method for rail health monitoring. Acoustic emission (AE) as a practical real-time detection technology takes advantage of dynamic AE signal emitted from plastic deformation of material. Detection capacities of AE on rail defects have been verified due to its sensitivity and dynamic merits. Whereas the application under normal train service circumstance has been impeded by synchronous background noises, which are directly linked to the wheel speed. In this paper, surveys on a wheel-rail rolling rig are performed to investigate defect AE signals with varying speed. A dynamic denoising method based on Kalman filter is proposed and its detection effectiveness and flexibility are demonstrated by theory and computational results. Moreover, after comparative analysis of modelling precision at different speeds, it is predicted that the method is also applicable for high speed condition beyond experiments.

    2013-09-01

    Full Text Available This article presents the results of a comprehensive disaggregated commodity flow model for South Africa. The wealth of data available enables a segmented analysis of future freight transportation demand in order to assist with the prioritisation of transportation investments, the development of transport policy and the growth of the logistics service provider industry. In 2011, economic demand for commodities in South Africa’s competitive surface-freight transport market amounted to 622 million tons and is predicted to increase to 1834m tons by 2041, which is a compound annual growth rate of 3.67%. Fifty percent of corridor freight constitutes break bulk; intermodal solutions are therefore critical in South Africa. Scenario analysis indicates that 80%of corridor break-bulk tons can by serviced by four intermodal facilities – in Gauteng, Durban, Cape Town and Port Elizabeth. This would allow for the development of an investment planning hierarchy, enable industry targeting (through commodity visibility, ensure capacity development ahead of demand and lower the cost of logistics in South Africa.

    1986-06-01

    The Pacific Northwest Laboratory developed techniques for calculating estimates of nuclear-waste shipping costs and compiled a listing of representative data that facilitate incorporation of reference shipping costs into varius logistics analyses. The formulas that were developed can be used to estimate costs that will be incurred for shipping spent fuel or nuclear waste by either legal-weight truck or general-freight rail. The basic data for this study were obtained from tariffs of a truck carrier licensed to serve the 48 contiguous states and from various rail freight tariff guides. Also, current transportation regulations as issued by the US Department of Transportation and the Nuclear Regulatory Commission were investigated. The costs that will be incurred for shipping spent fuel and/or nuclear waste, as addressed by the tariff guides, are based on a complex set of conditions involving the shipment origin, route, destination, weight, size, and volume and the frequency of shipments, existing competition, and the length of contracts. While the complexity of these conditions is an important factor in arriving at a ''correct'' cost, deregulation of the transportation industry means that costs are much more subject to negotiation and, thus, the actual fee that will be charged will not be determined until a shipping contract is actually signed. This study is designed to provide the baseline data necessary for making comparisons of the estimated costs of shipping spent fuel and/or nuclear wastes by truck and rail transportation modes. The scope of the work presented in this document is limited to the costs incurred for shipping, and does not include packaging, cask purchase/lease costs, or local fees placed on shipments of radioactive materials

    In any context, operation and management of transportation systems are key issues which may affect both life quality and economic development. In large urban agglomerations, an efficient public transportation system may help abate the negative externalities of private car use such as congestion, air and noise pollution, accident and fuel consumption, without excessively penalizing user travel times or zone accessibility. Thus, this study is conducted to appraise the Malaysian rural rail transit operation and management system, which are considered important as there are many issues and solution in integration of the services that need to be tackled more conscientiously. The purpose of this paper is to describe some of the most important issues on integration of services and rail transit system in Malaysian and how to solve or reduce these problems and conflicts. In this paper, it consists of the historical development of rail transit construction in Malaysia. This paper also attempts to identify the important issues related to rail transit services and integration in Malaysian rural rail operation and management system. Comparison is also conducted with other countries such as UK, France, and Japan. Finally, a critical analysis is presented in this paper by looking at the possible application for future Malaysian rail transit operation system and management, especially focusing on enhancing the quality of Malaysian rural rail transit. In conclusion, this paper is expected to successfully review and appraise the existing Malaysian rural rail transit operation and management system pertaining to issues & solution in integration. It is also hoped that reformation or transformation of present service delivery quality of the rail transit operation and management will enable Malaysia to succeed in transforming Malaysian transportation system to greater heights.

    Halstead, R. J.; Dilger, F.; Moore, R. C.

    2003-01-01

    The proposed Yucca Mountain repository site currently lacks rail access. The nearest mainline railroad is almost 100 miles away. Absence of rail access could result in many thousands of truck shipments of spent nuclear fuel and high-level radioactive waste. Direct rail access to the repository could significantly reduce the number of truck shipments and total shipments. The U.S. Department of Energy (DOE) identified five potential rail access corridors, ranging in length from 98 miles to 323 miles, in the Final Environmental Impact Statement (FEIS) for Yucca Mountain. The FEIS also considers an alternative to rail spur construction, heavy-haul truck (HHT) delivery of rail casks from one of three potential intermodal transfer stations. The authors examine the feasibility and cost of the five rail corridors, and DOE's alternative proposal for HHT transport. The authors also address the potential for rail shipments through the Las Vegas metropolitan area

  2. SELF-DIAGNOSIS METHOD FOR CHECKING THE WAYSIDE SYSTEMS FOR WHEEL-RAIL VERTICAL LOAD MEASUREMENT

    Directory of Open Access Journals (Sweden)

    Daniele CORTIS

    2017-12-01

    Full Text Available Nowadays, wayside measurement systems of wheel-rail contact forces have acquired great relevance for the monitoring of rolling stock, especially for freight trains. Thanks to these solutions, infrastructure managers can check and monitor the status of rolling stock and, when necessary, impose corrective actions for the railway companies. On the other hand, the evaluation of contact forces is part of the rolling stock authorisation process [1] and a mainstone for the study of the running stability. The data provided by these measurements could give useful information to correlate the wear of the track with the frequency of applied loads, helping in the development of a better maintenance strategy of railway networks [2]. In this paper, the monitoring of vertical forces is based on the SMCV (Vertical Loads Monitoring System method, where shear strains of the rail web are measured with a simple combination of four electrical strain gauges, placed on both sides of the rail web along each span. The research has identified self-diagnosis methods for the SMCV system to ensure the reliability and the quality of the measurements and to extend the knowledge of the system. The recorded signals have been processed and converted into easily interpretable physical quantities by means of MATLAB® algorithm.

  3. Reliability assessment of a multistate freight network for perishable merchandise with multiple suppliers and buyers

    Science.gov (United States)

    Lin, Yi-Kuei; Yeh, Cheng-Ta; Huang, Cheng-Fu

    2017-01-01

    This study develops a multistate freight network for single and perishable merchandise to assess the freight performance, where a node denotes a supplier, a distribution centre, or a buyer, while a logistics company providing a freight traffic service is denoted by an edge. For each logistics company, carrying capacity should be multistate since partial capacity may be reserved by some customers. The merchandise may perish or be perished during conveyance because of disadvantageous weather or collision in carrying such that the number of intact cargoes may be insufficient for the buyers. Hence, according to the perspective of supply chain management, the reliability, a probability of the network to successfully deliver the cargoes from the suppliers to the buyers subject to a budget, is proposed to be a performance index, where the suppliers and buyers are not the previous customers. An algorithm in terms of minimal paths to assess the reliability is developed. A fruit logistics case is adopted to explore the managerial implications of the reliability using sensitivity analysis.

  4. Energy efficiency practices among road freight hauliers

    International Nuclear Information System (INIS)

    Liimatainen, Heikki; Stenholm, Pekka; Tapio, Petri; McKinnon, Alan

    2012-01-01

    The reduction of greenhouse gases (GHG) is a highly prevalent public policy goal among European Union member countries. In the new White Paper on transport, the role of road freight transports in this is strongly emphasized. This far, however, the efficiency practices utilised in logistics firms are less studied. Drawing from policy goals and new survey data on 295 road transport firms our results show that hauliers are aware of the possible energy efficiency actions but lack the knowledge and resources to fully utilize them. Energy efficiency seems also to be unimportant for many shippers, so there are no incentives for hauliers to improve it. Examples from various countries show that clear energy efficiency improvements can be achieved with active cooperation between hauliers, shippers and policy makers. Such cooperation can be developed in Finland through the sectoral energy efficiency agreements. The novelty and the utility of these results allow scholars to answer important open questions in the national-level determinants of enhancing energy efficiency practices among road freight hauliers, and contribute to our understanding of how these can be fostered in public policies. - Highlights: ► Hauliers still monitor their fuel consumption with unsophisticated methods. ► Larger hauliers are more active in energy efficiency related issues than smaller ones. ► Hauliers are aware of energy efficiency actions, but lack knowledge of implementation. ► Finnish energy efficiency agreement provides a good framework for public policies. ► Companies that monitor and improve energy efficiency may gain competitive advantage.

  6. The rebound effect on road freight transport: Empirical evidence from Portugal

    International Nuclear Information System (INIS)

    Matos, Fernando J.F.; Silva, Francisco J.F.

    2011-01-01

    Because a large proportion of total operating costs for transportation companies goes towards energy, a reduction in energy operating costs, brought about by an increase in fleet fuel efficiency, or an increase in operational efficiency, results in a change in the relative cost of road freight transportation. This fact could result in an increase in the demand for such services. If this is true, the result would be an increase in total fuel consumption. Consequently, that part of the energy savings obtained through the increased energy efficiency would be lost. The existence of a 'Rebound Effect' is especially important in the road freight transportation sector and is crucial for the definition of a national energy policy. In this study, data from the road freight transportation sector in Portugal for the years of 1987 through 2006 was analyzed. It was determined that an increase in energy efficiency did not cause a backfire, but did cause a total direct rebound effect of 24.1%. In addition, fleet operators were more inclined to adopt operational efficiencies than technological fuel efficiencies as a means of increasing the total operational efficiency. - Research highlights: → We estimate a direct rebound effect for road freight transportation in Portugal. → The functional form chosen was a log-log model and the estimation method used was the two stage least squares model. → Increasing energy efficiency by 1% results in a reduction of 0.759% in energy consumption (a direct rebound effect of about 24.1%). → Estimates of reduced fuel consumption without considering the direct rebound effect may be overestimated by about 0.87 million liters of diesel per year for each percentage point increase in energy efficiency.

  7. Air freight in the Stockholm region with focus on Eskilstuna Airport

    Directory of Open Access Journals (Sweden)

    Kjell-Åke Allan Brorsson

    2016-02-01

    Full Text Available Purpose: The purpose of this article is to analyse the conditions for commencing air freight operations at the regional Eskilstuna Airport in Sweden, which require investments in airport infrastructure of at least SEK 140 –180 million. Design/ methodology: The qualitative data collection for the study was carried out through open-ended interviews with representatives of airport management, staff, representatives of residents, and actors and stakeholders in the field. In addition, much written material was collected from different authorities. Document analysis was used to systematically evaluate and review the collected documents. Content analysis was applied to organize collected data into categories. Based on the reports, decisions, environmental scanning and interviews, the data have been coded and categorized in tables via thematic analysis. Findings: The major findings of the study are that Eskilstuna Airport lacks cargo facilities and has limited apron space, and that there is strong competition from four other airports in the Stockholm region. The prospects for permanent air freight operations at Eskilstuna Airport are therefore not favourable in the current situation. However, if the development of Eskilstuna Logistics Park and the concept of inter modal highway-rail transportation are successful, they could serve as a major driving force for the development of air cargo. Furthermore, with sustainable development as a guiding principle, there is great potential to develop an airport with a high standard of environmental profile. Originality/ value: My findings are of great value to managers of airports and cargo airlines, as they highlight some of the competition aspects associated with engaging in air cargo at regional airports. The study fills a gap in existing research whose main focus is environmental issues concerning airports in general.

    Full Text Available Actual trends of worldwide railway transport development are characterized by increasing speed and growth of railway’s axels load. Increasing load together with transverse, longitudinal wheel displacement and braking on the rails results into heavy surface tension. One of many applications for bainitic steel is in railway transport for highly strength and wear resistant rails. Rail steel must be designed to be able to resist plastic deformation, wear, rolling contact fatigue, bending stress and thermal stress during rail welding process and rails resurfacing.

  10. Parameters Studies on Surface Initiated Rolling Contact Fatigue of Turnout Rails by Three-Level Unreplicated Saturated Factorial Design

    Directory of Open Access Journals (Sweden)

    Xiaochuan Ma

    2018-03-01

    Full Text Available Surface initiated rolling contact fatigue (RCF, mainly characterized by cracks and material stripping, is a common type of damage to turnout rails, which can not only shorten service life of turnout but also lead to poor running safety of vehicle. The rail surface initiated RCF of turnouts is caused by a long-term accumulation, the size and distribution of which are related to the dynamic parameters of the complicated vehicle-turnout system. In order to simulate the accumulation of rail damage, some random samples of dynamic parameters significantly influencing it should be input. Based on the three-level unreplicated saturated factorial design, according to the evaluation methods of H, P and B statistic values, six dynamic parameters that influence the rail surface initiated RCF in turnouts, namely running speed of vehicle, axle load, wheel-rail profiles, integral vertical track stiffness and wheel-rail friction coefficient, are obtained by selecting 13 dynamic parameters significantly influencing the dynamic vehicle-turnout interaction as the analysis factors, considering four dynamic response results, i.e., the normal wheel-rail contact force, longitudinal creep force, lateral creep force and wheel-rail contact patch area as the observed parameters. In addition, the rail surface initiated RCF behavior in turnouts under different wheel-rail creep conditions is analyzed, considering the relative motion of stock/switch rails. The results show that the rail surface initiated RCF is mainly caused by the tangential stress being high under small creep conditions, the normal and tangential stresses being high under large creep conditions, and the normal stress being high under pure spin creep conditions.

  16. Calculation of freight externality costs for South Africa

    Directory of Open Access Journals (Sweden)

    Stefaan Swarts

    2012-11-01

    Full Text Available The purpose of this study is to quantify the marginal external costs associated with freight transport in South Africa. Six cost elements are included as externality cost items, namely, costs related to accidents, emissions, roadway land availability, policing, noise and congestion. Inputs in the calculations were a gravity-oriented freight flow model, a road transport cost model, actual transport costs for other modes, a warehousing cost survey, an inventory delay calculation and various national sources of information such as accident statistics and government budgets. Estimation techniques resulted in advances for externality cost measurement in South Africa. The quantification of the cost elements will be used to update the South African Freight Demand Model. The results show that the cost of transportation would have been 20% more if external factors were taken into account. The marginal rates of externalities can be used to develop scenarios based on alternative choices for South Africa's freight transport infrastructure configuration.

  5. Rail electrodynamics in a plasma armature railgun

    International Nuclear Information System (INIS)

    1991-01-01

    A model is developed to investigate rail electrodynamics in a plasma armature railgun. This model describes the rail motion in response to the transitory Lorentz force and the compressive restoration force from the material which is between the rails and the containment structure. In this model the distance between the rails is found to oscillate with a frequency of β. The magnetic field and the dynamic behavior of the rails induce local electric fields. We investigate the significance of these electric fields in the laboratory frame and in the projectile frame. In the lab frame, rail electrodynamics induces local electric fields which have maximums spaced behind the projectile at locations where βt p is an odd multiple of π, where t p is the time since the projectile has passed an axial location on the rails. When the projectile is accelerating, rail dynamics induce electric fields in the projectile frame which have maximums where βt p is an even multiple of π. As the projectile velocity increases, the locations of the peak voltages move farther behind the projectile. For the CHECMATE railgun, calculations indicate that the rail displacement is on the order of 2 mm, the rail velocity is on the order of 50 m/s, and the voltages induced in the projectile frame are on the order of 20--40 V

    Very few contributions in the literature have dealt with the issue of social exclusion related to High Speed Rail systems. The objective of this manuscript is to understand what are the factors excluding users from choosing High Speed Rail services considering as case study Spain. For this purpose, a Revealed Preference survey was employed in November and December 2015. A questionnaire was submitted to users of the Spanish transport systems travelling for long distance-journeys. The aim was that of investigating their perception of High Speed Rail system and the factors inhibiting passengers or excluding them from its use. Data about their socioeconomic characteristics were collected as well. The main result of the survey has been that a relationship between social exclusion and High Speed Rail in Spain is present, especially in terms of geographical exclusion. (Author)

  11. A Bi-Level Programming Model for the Railway Express Cargo Service Network Design Problem

    Directory of Open Access Journals (Sweden)

    Boliang Lin

    2018-06-01

    Full Text Available Service network design is fundamentally crucial for railway express cargo transportation. The main challenge is to strike a balance between two conflicting objectives: low network setup costs and high expected operational incomes. Different configurations of these objectives will have different impacts on the quality of freight transportation services. In this paper, a bi-level programming model for the railway express cargo service network design problem is proposed. The upper-level model forms the optimal decisions in terms of the service characteristics, and the low-level model selects the service arcs for each commodity. The rail express cargo is strictly subject to the service commitment, the capacity restriction, flow balance constraints, and logical relationship constraints among the decisions variables. Moreover, linearization techniques are used to convert the lower-level model to a linear one so that it can be directly solved by a standard optimization solver. Finally, a real-world case study based on the Beijing–Guangzhou Railway Line is carried out to demonstrate the effectiveness and efficiency of the proposed solution approach.

    Analysis of the volatile and semivolatile fractions collected after use of the TOR lubricant indicated that other than contaminants in the collection laboratory, no compounds on the EPA's Target Compound Lists (Tables 2 and 5) were detected in these fractions. The data of these qualitative analyses, given in the various tables in the text, indicate only the relative amounts of the tentatively identified compounds. The authors recommend that quantitative analysis be performed on the volatile and semivolatile fractions to allow confirmation of the tentatively identified compounds and to obtain absolute amounts of the detected compounds. Additionally, the semivolatile fraction should be analyzed by liquid chromatography/mass spectrometry to identify compounds that are not chromatographable under the temperature program used for determination of semivolatile compounds. Introducing the top-of-rail (TOR) lubricant into the wheel/rail interface results in a reduction of almost 60% of lateral friction force over the forces encountered under dry conditions. This reveals good potential for energy savings, as well as wear reduction, for railroad companies. In TOR lubrication, an increase in the angle of attack and axle load results in increased lateral friction and rate of lubricant consumption. The most efficient TOR lubricant quantity to be used in the wheel/rail interface must be calculated precisely according to the number of cars, axle loads, train speed, and angle of attack.

    Theoretical and experimental investigations on hybrid rail accelerators are presented. It is shown that the side surface areas and in some cases sabots of the projectile can be used to provide substantial amount of additional thrust. Moreover, it is shown that in most cases examined, external magnetic fields can be conveniently incorporated in the accelerator designs to supplement the rail-induced fields. Total thrusts in excess of 10 MN for kilogram-sized projectiles can in principle be established with driving currents of the order of 1 MA. No obvious stress limitations are foreseen. The percentages of thrust from external magnetic fields are sufficiently high that the use of which should be encouraged. The increased flexibility in the projectile shapes available permits the use of the proposed hybrid electromagnetic launcher technology in a variety of new areas, such as thrust boosts in conventional chemical rockets and other similar applications. Furthermore, the additional thrust obtained from the use of side surface areas greatly increases the maximum permissable thrust otherwise limited by material strength considerations. Thrust analyses for projectiles in several hybrid rail accelerator designs are discussed. Some laboratory experimental observations are presented

  18. Longitudinal review of state-level accident statistics for carriers of interstate freight

    International Nuclear Information System (INIS)

    Saricks, C.; Kvitek, T.

    1994-03-01

    State-level accident rates by mode of freight transport have been developed and refined for application to the US Department of Energy's (DOE's) environmental mitigation program, which may involve large-quantity shipments of hazardous and mixed wastes from DOE facilities. These rates reflect multi-year data for interstate-registered highway earners, American Association of Railroads member carriers, and coastal and internal waterway barge traffic. Adjustments have been made to account for the share of highway combination-truck traffic actually attributable to interstate-registered carriers and for duplicate or otherwise inaccurate entries in the public-use accident data files used. State-to-state variation in rates is discussed, as is the stability of rates over time. Computed highway rates have been verified with actual carriers of high- and low-level nuclear materials, and the most recent truck accident data have been used, to ensure that the results are of the correct order of magnitude. Study conclusions suggest that DOE use the computed rates for the three modes until (1) improved estimation techniques for highway combination-truck miles by state become available; (2) continued evolution of the railroad industry significantly increases the consolidation of interstate rail traffic onto fewer high-capacity trunk lines; or (3) a large-scale off-site waste shipment campaign is imminent

  19. The standardised freight container: vector of vectors and vector-borne diseases.

    Science.gov (United States)

    Reiter, P

    2010-04-01

    The standardised freight container was one of the most important innovations of the 20th Century. Containerised cargoes travel from their point of origin to their destination by ship, road and rail as part of a single journey, without unpacking. This simple concept is the key element in cheap, rapid transport by land and sea, and has led to a phenomenal growth in global trade. Likewise, containerised air cargo has led to a remarkable increase in the inter-continental transportation of goods, particularly perishable items such as flowers, fresh vegetables and live animals. In both cases, containerisation offers great advantages in speed and security, but reduces the opportunity to inspect cargoes in transit. An inevitable consequence is the globalisation of undesirable species of animals, plants and pathogens. Moreover, cheap passenger flights offer worldwide travel for viral and parasitic pathogens in infected humans. The continued emergence of exotic pests, vectors and pathogens throughout the world is an unavoidable consequence of these advances in transportation technology.

  20. Protecting public health and global freight transportation systems during an influenza pandemic.

    Luke, Thomas C; Rodrigue, Jean-Paul

    2008-01-01

    The H5N1 influenza threat is resulting in global preparations for the next influenza pandemic. Pandemic influenza planners are prioritizing scarce vaccine, antivirals, and public health support for different segments of society. The freight, bulk goods, and energy transportation network comprise the maritime, rail, air, and trucking industries. It relies on small numbers of specialized workers who cannot be rapidly replaced if lost due to death, illness, or voluntary absenteeism. Because transportation networks link economies, provide critical infrastructures with working material, and supply citizens with necessary commodities, disrupted transportation systems can lead to cascading failures in social and economic systems. However, some pandemic influenza plans have assigned transportation workers a low priority for public health support, vaccine, and antivirals. The science of Transportation Geography demonstrates that transportation networks and workers are concentrated at, or funnel through, a small number of chokepoints and corridors. Chokepoints should be used to rapidly and efficiently vaccinate and prophylax the transportation worker cohort and to implement transmission prevention measures and thereby protect the ability to move goods. Nations, states, the transportation industry and unions, businesses, and other stakeholders must plan, resource, and exercise, and then conduct a transportation health assurance and security campaign for an influenza pandemic.

    2017-01-01

    Full Text Available Railway, subway, airplane, and other transportation systems have drawn an increasing interest on the use of wireless communications for critical and noncritical services to improve performance, reliability, and passengers experience. Smart transportation systems require the use of critical communications for operation and control, and wideband services can be provided using noncritical communications. High speed train (HST is one of the best test cases for the analysis of communication links and specification of the general requirements for train control and supervision, passenger communications, and onboard and infrastructure wireless sensors. In this paper, we analyze in detail critical and noncritical networks mainly using the HST as a test case. First, the different types of links for smart rail transportation are described, specifying the main requirements of the transportation systems, communications, and their applications for different services. Then, we propose a network architecture and requirements of the communication technologies for critical and noncritical data. Finally, an analysis is made for the future technologies, including the fifth-generation (5G communications, millimeter wave (mmWave, terahertz (THz, and satellites for critical and high-capacity communications in transportation.

  11. Decomposing road freight energy use in the United Kingdom

    International Nuclear Information System (INIS)

    Sorrell, Steve; Lehtonen, Markku; Stapleton, Lee; Pujol, Javier; Champion, Toby

    2009-01-01

    Applying the techniques of decomposition analysis we estimate the relative contribution of ten variables (termed 'key ratios') plus GDP to the change in UK road freight energy use over the period 1989-2004 inclusive. The results are best interpreted as an estimate of the percentage growth in energy consumption that would have resulted from the change in the relevant factor (e.g. length of haul) had the other factors remained unchanged. The results demonstrate that the main factor contributing to the decoupling of UK road freight energy consumption from GDP was the decline in the value of domestically manufactured goods relative to GDP. Over the period 1989-2004 this largely offset the effect of increases in GDP on road freight energy consumption. While the decline in domestic manufacturing was to some extent displaced by increases in imports, the net effect of these supply factors, together with shifts in the commodity mix, has been to reduce UK road freight energy consumption by 30.1%. The net effect on global carbon dioxide (CO 2 ) emissions is likely to be somewhat less beneficial, since many freight movements associated with the manufacture of imported goods have simply been displaced to other countries.

  12. Purging of working atmospheres inside freight containers.

    Science.gov (United States)

    Braconnier, Robert; Keller, François-Xavier

    2015-06-01

    This article focuses on prevention of possible exposure to chemical agents, when opening, entering, and stripping freight containers. The container purging process is investigated using tracer gas measurements and numerical airflow simulations. Three different container ventilation conditions are studied, namely natural, mixed mode, and forced ventilation. The tests conducted allow purging time variations to be quantified in relation to various factors such as container size, degree of filling, or type of load. Natural ventilation performance characteristics prove to be highly variable, depending on environmental conditions. Use of a mechanically supplied or extracted airflow under mixed mode and forced ventilation conditions enables purging to be significantly accelerated. Under mixed mode ventilation, extracting air from the end of the container furthest from the door ensures quicker purging than supplying fresh air to this area. Under forced ventilation, purging rate is proportional to the applied ventilation flow. Moreover, purging rate depends mainly on the location at which air is introduced: the most favourable position being above the container loading level. Many of the results obtained during this study can be generalized to other cases of purging air in a confined space by general ventilation, e.g. the significance of air inlet positioning or the advantage of generating high air velocities to maximize stirring within the volume. © The Author 2015.

    Replacement of the rail in under-sea tunnel such as the Kammon Tunnel is carried out very five years because of the severe corrosion caused by the humid state due to the leakage of sea water or the mist of sea water swept up by the passing trains. In this study, salt water spraying or sea water spraying test is carried out using Zn-Al alloy with the corrosion resistance and thermal spray efficiency even higher than those of Zn or Al. A rail coated by thermal spray of Zn-15mass%Al alloy has been laid by trial in the practical rail road of Kammon Tunnel for 5 years and 3 months, the deterioration degree of the coating, pitting depth, actual fatigue strength, etc. are evaluated. Further, these factors of a rail re-coated by Zincrich Primer+Tar Epoxy and a bare rail laid at the same time are evaluated for comparison. It is presumed by the results of the examination about the service life of a rail coated by the thermal spray of Zn-Al alloy based on the pitting depth in the rail base that the service life of such coated rail is more than twice as that of the bare rails used currently. 5 refs., 14 figs., 3 tabs.

    Full Text Available In terms of building a network parking strategies for freight transport may be considered two variants: a building (completing car parks on abandoned of border crossings, respectively building a whole new network of parks. Creating a network of parks for freight is in the interest of the Slovak Republic as well as the European Union. The subsequent optimization is dependent on the quality of road infrastructure and the traffic intensity in the monitored sections. It is therefore important selection of suitable candidates, administrators and their subsequent assessment of the appropriateness and services provided in selected locations. Identification of parking in the SR enables to choose the effective solution for intelligent networking and secure parking.

  16. Comparison of Urban and Suburban Rail Transport in Germany and in the Czech Republic

    Directory of Open Access Journals (Sweden)

    Seidenglanz Daniel

    2014-06-01

    Full Text Available Rail transport is an environmentally friendly form of passenger transport which can be utilized effectively also in urban and suburban transport systems. The paper describes the urban and suburban rail transport system including comparison of selected Czech (Prague, Brno and Ostrava and German metropolitan regions (Munich, Nuremberg and Dresden. Its aim is to analyze the importance of various factors influencing the differences between the situation in Germany and in the Czech Republic. Therefore, the research question is whether these differences are primarily caused by a different liberalization stage, or whether they are a result of other factors such as available infrastructure, investment level, rail transport services budget, structure and activity of ordering bodies and coordinators or geographical context. The supply of city and suburban rail transport is quite good in Germany and in the Czech Republic, although trains in Munich, Nuremberg and Dresden run more frequently, faster and are better interconnected with car transport. German rail transport sector is at a higher stage of liberalization, and tendering procedures are the preferred selection method for contractor carriers. However, a degree of liberalization of the railway sector is not the key marker indicating a better standard of urban and suburban rail transport in Germany because it is the high standard which is achieved as the consequence of the professional activity of the ordering bodies and train service coordinators in combination with geographical conditions, available financial sources and effective transport infrastructure. On the other hand, the importance of liberalization cannot be totally overlooked as tenders are a tool for the ordering bodies to strongly affect the price and quality of transport services in their area. The supply of better quality and attractive transport to passengers could increase the usage of rail transport in metropolitan regions and could

Increasingly, rail investments are specifically promoted to reshape the built environment for property-led economic development. In these cases, new investment in rail transit is claimed to facilitate particular types of land use changes, mostly in the form of dense multi-family residential and mixed-use developments. Although rail’s effects on land use are widely claimed, scholarly evaluations offer mixed results. This paper examines two potential reasons for these mixed results. First, as most empirical examinations tend to be conducted shortly after new transit investment opens analysis is often criticized on the basis that short time frames may not allow land use changes to materialize. The second is that rail investment often includes changes to local zoning and land use regulations, creating opportunities for types of development that were previously outlawed. This paper evaluates these two critiques through an analysis of long-term land use effects associated with new rail transit service in San Diego, California. The results suggest that even after three decades of development cycles, rail transit has not led to consistent regulatory patterns of increased density or new mixed-use development.

  7. Rail inspection using noncontact laser ultrasonics

    International Nuclear Information System (INIS)

    Kim, Nak Hyeon; Sohn, Hoon; Han, Soon Woo

    2012-01-01

    In this study, a noncontact laser ultrasonic system is proposed for rail defect detection. An Nd Yag pulse laser is used for generation of ultrasonic waves, and the corresponding ultrasonic responses are measured by a laser Doppler vibrometer. For the detection of rail surface damages, the shape of the excitation laser beam is transformed into a line. On the other hand, a point source laser beam is used for the inspection of defects inside a rail head. Then, the interactions of propagating ultrasonic waves with defects are examined using actual rail specimens. Amplitude attenuation was mainly observed for a surface crack, and reflections were most noticeable from an internal damage. Finally, opportunities and challenges associated with real time rail inspection from a high speed train are discussed

  8. The development of ISO freight containers as IP-2 packagings

    International Nuclear Information System (INIS)

    Janicki, M.C.; Vaughan, R.A.

    1993-01-01

    Design specifications were developed for ISO freight containers to meet the requirements of the transport regulations in the 1985 Edition of IAEA SS6, and to maximize the technical and commercial benefits offered to consignors by this type of container for the transport and handling of bulk LSA/SCO materials. A range of IP-2 ISO freight containers have been designed and built to these specifications and are in use in the UK. This paper discusses the regulatory considerations which had to be reviewed and interpreted in developing freight containers as Industrial Package Type 2 (IP-2) packagings and the development of performance standards to meet the regulatory requirements. Outline details of the packages developed are indicated together with examples of handling equipment developed to facilitate loading and unloading. (J.P.N.)

  9. Rail transportation of Fernald remediation waste

    1995-01-01

    Remediation of the Department of Energy (DOE) Fernald site located north of Cincinnati will generate large quantities of low-level radwaste. This volume includes approximately 1,050,000 tons of material to be removed from eight waste pits comprising Operable Unit 1 (OU-1). The remedial alternative selected includes waste material excavation, drying and transportation by rail to a burial site in the arid west for disposal. Rail transportation was selected not only because rail transportation is safer than truck transportation, but also because of the sheer magnitude of the project and the availability of bulk rail car unloading facilities at a representative disposal site. Based upon current waste quantity estimates as presented in the Feasibility Study for OUI, a fully-loaded 47-car unit train would depart the Fernald site weekly for five years. This paper illustrates the steps taken to obtain agency and public acceptance of the Record of Decision for the remedy which hinged on rail transportation. A preliminary, but detailed, rail transportation plan was prepared for the project to support a series of CERCLA public meetings conducted in late 1994. Some of the major issues addressed in the plan included the following: (1) Scope of project leading to selection of rail transportation; (2) Waste classification; (3) Rail Company overview; (4) Train configuration and rail car selection; (5) Routing; (6) Safety; (7) Prior Notification Requirements (8) Emergency Response. A series of three public meetings identified a number of issues of prime concern to Fernald stakeholders. Following resolution of these issues during the public comment period, a Record of Decision (ROD) approving implementation of the rail transportation strategy was approved pending incorporation of EPA and State of Ohio comments on December 22, 1994

    This paper reviews publication that focuses on multimodal freight transportation planning under disruptions. In this paper, disruptions are specified by the level of the disruptions occurs and the scope of its effect. This becomes an important distinction since the cause and effect that may occur at different levels. The failure to make this distinction has implications for how we understand and manage. The reviewed papers include those that develop framework, model, and technical procedure for freight transportation. Finally, we provide an outlook of future research directions on the domain of transportation planning.

    2007-12-01

    With all the responsibilities placed on materials managers, it is not surprising that some processes such as shipping are overlooked when it comes to cutting costs. But by taking a closer look at inbound freight costs, materials managers might discover an untapped resource for saving thousands, and in some cases millions, of dollars. Finding out how costs vary among vendors for shipping the same type of item can eliminate unnecessary freight charges. Initially, the process takes time, but the bottom line will be better for it.

  12. Streamlining Transportation Corridor Planning Processess: Freight and Traffic Information

    Energy Technology Data Exchange (ETDEWEB)

    Franzese, Oscar [ORNL

    2010-08-01

    The traffic investigation is one of the most important parts of an Environmental Impact Statement of projects involving the construction of new roadway facilities and/or the improvement of existing ones. The focus of the traffic analysis is on the determination of anticipated traffic flow characteristics of the proposed project, by the application of analytical methods that can be grouped under the umbrella of capacity analysis methodologies. In general, the main traffic parameter used in EISs to describe the quality of traffic flow is the Level of Service (LOS). The current state of the practice in terms of the traffic investigations for EISs has two main shortcomings. The first one is related to the information that is necessary to conduct the traffic analysis, and specifically to the lack of integration among the different transportation models and the sources of information that, in general, reside in GIS databases. A discussion of the benefits of integrating CRS&SI technologies and the transportation models used in the EIS traffic investigation is included. The second shortcoming is in the presentation of the results, both in terms of the appearance and formatting, as well as content. The presentation of traffic results (current and proposed) is discussed. This chapter also addresses the need of additional data, in terms of content and coverage. Regarding the former, other traffic parameters (e.g., delays) that are more meaningful to non-transportation experts than LOS, as well as additional information (e.g., freight flows) that can impact traffic conditions and safety are discussed. Spatial information technologies can decrease the negative effects of, and even eliminate, these shortcomings by making the relevant information that is input to the models more complete and readily available, and by providing the means to communicate the results in a more clear and efficient manner. The benefits that the application and use of CRS&SI technologies can provide to

    Paolo Beria

    2011-10-01

    Full Text Available Italy has undergone, in the last 15 years, an exceptional public financial effort to build approximately 1,000 km of high speed rail lines. Further extensions are under construction or planned, especially in the most important international relations. This network is widely considered as fundamental to comply the European vision of a continental-wide transport system.The paper analyses the past and the future of such network, where possible from a quantitative point of view. The first part of the article reviews the history of the Alta Velocità scheme, particularly focusing on the issues related to the economic regulation of the investments and the financial troubles at first and then on the present issues related to the regulation of rail services.The analysis of the supply, the time gains, the demand and the costs allows to build a simple but independent evaluation of the past projects from an ex-post perspective, pointing out the successes, but also important critical issues.The second part of the paper analyses the future expansion plans looking at the costs, the existing and expected demand and derives some policy indications and cost reduction strategies capable both to control public expenditure in a period of crisis and not to abandon the idea of a modern and effective rail network.

  18. Model for predicting the frequency of broken rails

    S. Vesković

    2012-04-01

    Full Text Available Broken rails can cause train delays, trains cancelations and, unfortunately, they are common causes of accidents. This affects planning of a resources, budget and organization of railway track maintenance. Planning of railway track maintenance cannot be done without an estimation of number of rails that will be replaced due to the broken rail incidents. There are many factors that influence broken rails and the most common are: rail age, annual gross tonnage, degree of curve and temperature in the time of breakage. The fuzzy logic model uses acquired data as input variables to predict the frequency of broken rails for the certain rail types on some Sections.

  19. Rail-induced Traffic in China

    2017-11-01

    Full Text Available The rapid development of China’s railway has exerted an enormous influence on the intercity passenger transport structure in recent years. However, it has not satisfied the passengers’ travel demand due to induced traffic. This paper is committed to solving such issue, with the aim of satisfying the current travel demand, and of anticipating the demand of the predicted traffic growth over the next 20 to 30 years. The paper has considered the increase in rail passenger kilometres caused by the growth of rail kilometres as rail-induced traffic. Based on the concept and former research of induced traffic, the panel data of 26 provinces and 3 municipalities of China between the year 2000 and 2014 were collected, and the elasticity models (including elasticity-based model, distributed lag model, high-speed rail (HSR elasticity model and rail efficiency model have been constructed. The results show the importance of model formation incorporation of rail-induced traffic. It is better to get the correct value in divided zones with different train frequencies or incorporation rail efficiency in cities or provinces. The lag time and rail types also need to be considered. In summary, the results analysis not only confirms the existence of rail-induced traffic, but also provides substantial recommendations to train operation planning.

  20. Development of rail access to the proposed repository site at Yucca Mountain

    International Nuclear Information System (INIS)

    Standish, P.N.; Seidler, P.E.; Andrews, W.B.; Shearin, G.

    1991-01-01

    In accordance with the Nuclear Waste Policy Amendment Act of 1987, Yucca Mountain was designated as the initial site to be investigated as a potential repository for the disposal of high-level radioactive waste. The Yucca Mountain site is an undeveloped area located on the southwestern edge of the Nevada Test Site (NTS), about 100 miles northwest of Las Vegas. The site currently lacks rail service or an existing right-of-way. If the Yucca Mountain site is found suitable for the repository, rail service is considered desirable by the Office of Civilian Radioactive Waste Management (OCRWM) program because of the potential of rail transportation to reduce (1) costs and (2) number of shipments, relative to highway transportation. Therefore, it is necessary to conduct a study to determine (1) that there are alignments for a potential rail line from existing mainline railroads to Yucca Mountain and (2) that these are consistent with present rail design standards and are acceptable relative to environmental and land access considerations

  1. Electrodynamic wear of rails in high current density rail gun discharges

    International Nuclear Information System (INIS)

    Edwards, W.T.; Caldwell, S.G.

    1984-01-01

    Significant advances in high current, high speed power sources, has in recent years allowed rail guns to produce very high velocity (> 10 km/sec) macroscopic particles (> 1/10 grams). A continuing problem is the structural integrity of the components under these loadings and in particular, the rail wear due to the high current density plasma contacts. In this investigation a small bore rail gun (6x5 mm) was used with a 10.6 kjoule capacitor energy source to examine the modes of rail damage. The rails were constructed of 110 copper base material. These rails were used in an uncoated condition and also with plasma sprayed coatings of W and W/WC. The resulting surface wear was characterized by standard metallurgical techniques and analyzed for the various coatings

    2016-09-01

    Full Text Available Most Colombian freight is transported on roads with barely acceptable conditions, and although there is a speculation about the need for a railway for freight transportation, there is not a study in Colombia showing the variables that influence the modal choice by the companies that generate freight transportation. This article presents the calculation of demand for a hypothetical railway through a discrete choice model. It begins with a qualitative research through focus group techniques to identify the variables that influence the choice of persons responsible for the transportation of large commercial companies in Antioquia (Colombia. The influential variables in the election were the cost and service frequency, and these variables were used to apply a Stated Preference (SP and Revealed Preference (RP survey, then to calibrate a Multinomial Logit Model (MNL, and to estimate the influence of each of them. We show that the probability of railway choice by the studied companies varies between 67% and 93%, depending on differences in these variables.

    The paper examines the possibility of using the DC electric gun principles as a space vehicle propulsion system, capable of producing intermediate thrust levels. The application of an electromagnetic launch technique, called the DC electric rail gun, to the space propulsion concept of O'Neill, is examined. It is determined that the DC electric rail gun offers very high projectile accelerations and a very significant potential for reducing the size and mass of a reaction motor for space application. A detailed description of rail gun principles is given and some simple expressions for the accelerating force, gun impedance, power supply requirements, and system performance are discussed

    2015-01-01

    The inspection of very large objects like sea freight containers with X-ray Computed Tomography (CT) is an emerging technology. A complete 3-D CT scan of a see-freight container takes several hours. Of course, this is too slow to apply it to a large number of containers. However, the benefits of a 3-D CT for sealed freight are obvious: detection of potential threats or illicit cargo without being confronted with legal complications or high time consumption and risks for the security personnel during a manual inspection. Recently distinct progress was made in the field of reconstruction of projections with only a relatively low number of angular positions. Instead of today’s 500 to 1000 rotational steps, as needed for conventional CT reconstruction techniques, this new class of algorithms provides the potential to reduce the number of projection angles approximately by a factor of 10. The main drawback of these advanced iterative methods is the high consumption for numerical processing. But as computational power is getting steadily cheaper, there will be practical applications of these complex algorithms in a foreseeable future. In this paper, we discuss the properties of iterative image reconstruction algorithms and show results of their application to CT of extremely large objects scanning a sea-freight container. A specific test specimen is used to quantitatively evaluate the image quality in terms of spatial and contrast resolution and depending on different number of projections

    2011-10-01

    Full Text Available Purpose: The objective of the present study is to select some feasible and sustainable logistic practices in order to improve the urban freight distribution in Bilbao city. Design/methodology/approach: After a thorough literature review and a benchmarking, Analytic Hierarchy Process (AHP techniques were used in order to support the decision making processes in order to select the most interesting practices. The criteria used for this selection were based on four factors: (1 improvement of the city freight distribution, (2 implementation possibility, (3 short and medium term applicability and (4 impact on the citizens of Bilbao. Findings: The paper identifies some specific problems that must be faced during the last stage of the logistics chain, where products are usually delivered to final customers in the urban environment. Research limitations/implications: Not all good urban freight distribution practices can be applied universally to all types of towns. Therefore, it is necessary to design some practices specifically to each particular city according to the physical characteristics of the city, the companies’ motivation and the citizens’ habits. Practical implications: All the agents involved in the city freight distribution should be aware of the benefits and problems that their actions cause. Originality/value: This study was carried out from a wide perspective that included researchers, logistics operators and local authorities.

    Regarding the problems in the reform of the railway tariff system and the pricing of the transport, by means of assaying the influence of the price elasticity on the artifice used for price, this article proposed multiple regressive model which analyzed price elasticity quantitatively. This model conclude multi-factors which influences on the price elasticity, such as the averagely railway freight charge, the averagely freight haulage of proximate supersede transportation mode, the GDP per capita in the point of origin, and a series of dummy variable which can reflect the features of some productive and consume demesne. It can calculate the price elasticity of different classes in different domains, and predict the freight traffic volume on different rate levels. It can calculate confidence-level, and evaluate the relevance of each parameter to get rid of irrelevant or little relevant variables. It supplied a good theoretical basis for directing the pricing of transport enterprises in market economic conditions, which is suitable for railway freight, passenger traffic and other transportation manner as well. SPSS (Statistical Package for the Social Science) software was used to calculate and analysis the example. This article realized the calculation by HYFX system(Ministry of Railways fund).

  5. Rail-to-rail low-power fully differential OTA utilizing adaptive biasing and partial feedback

    DEFF Research Database (Denmark)

    Tuan Vu, Cao; Wisland, Dag T.; Lande, Tor Sverre

    A fully differential rail-to-rail Operational Transconductance Amplifier (OTA) with improved DC-gain and reduced power consumption is proposed in this paper.

    Mazilu, T.; Leu, M.

    2017-08-01

    Wheel/rail vibration has many technical effects such as wear of the rolling surfaces, rolling noise, settlement of the ballast and subgrade etc. This vibration is depending on the rail pad characteristic and subsequently, it is important to have an accurate overview on the relation between the rail pad characteristic and the level of the wheel/rail vibration. To this end, much theoretical and experimental research has been developed in the past, and for the theoretical approach the track model, in general, and, particularly, the rail pad model is of crucial importance. Usually, the rail pad model is discrete model one, neglecting the length of the rail pad. This fact is questionable because the sleepers span is only 4 times the rail pad length. Using the rail pad discrete model, the rail response is overestimated when the frequency of the excitation equals the pinned-pinned resonance frequency. In this paper, a multi-discrete model for the rail pad, consisting in many Kelvin-Voigt parallel systems, is inserted into an analytical model of the track. The track model is reduced to a rail taken as infinite Timoshenko beam, discretely supported via rail pad, sleeper and ballast. The influence of the number of Kelvin-Voigt systems of the rail pad model on the rail response is analysed.

  8. Assessment of rail long-pitch corrugation

    Valehrach, Jan; Guziur, Petr; Riha, Tomas; Plasek, Otto

    2017-09-01

    The paper focuses on defects of the running surface of the rail, namely the rail corrugation defect and specifically long-pitch corrugation in curves of small radii. These defects cause a shorter life of the rails, greater maintenance costs and increase the noise and vibration pollution. Therefore, it is very important to understand the formation and development of the imperfection of the rails. In the paper, various sections of railway tracks in the Czech Republic are listed, each of them completed with comparison of defect development, the particular track superstructure, rolling stock, axle load, traffic load etc. Based on performed measurements, defect development has been proved as different on sections with similar (or even same) parameters. The paper assumes that a train velocity is the significant circumstance for defect development rates. Assessment of track section with under sleeper pads, which are expected to be the one of the possible ways to suppress the corrugation defect development, is included in evaluation.

    Thornhill, L.; Battech, J.

    1991-01-01

    In this paper the authors examine the processes by which current is transferred from the cathode rail to the plasma armature in an arc-driven railgun. Three electron emission mechanisms are considered, namely thermionic emission, field-enhanced thermionic emission (or Schottky emission), and photoemission. The author's calculations show that the dominant electron emission mechanism depends, to a great extent, on the work function of the rail surface, the rail surface temperature, the electric field at the rail surface, and the effective radiation temperature of the plasma. For conditions that are considered to be typical of a railgun armature, Schottky emission is the dominant electron emission mechanism, providing current densities on the order of 10 9 A/m 2

  19. Environmental, public health, and safety assessment of fuel pipelines and other freight transportation modes

    International Nuclear Information System (INIS)

    Strogen, Bret; Bell, Kendon; Breunig, Hanna; Zilberman, David

    2016-01-01

    Highlights: • Externalities are examined for pipelines, truck, rail, and barge. • Safety impact factors include incidences of injuries, illnesses, and fatalities. • Environmental impact factors include CO_2eq emissions and air pollution disease burden. • Externalities are estimated for constructing and operating a large domestic pipeline. • A large pipeline has lower cumulative impacts than other modes within ten years. - Abstract: The construction of pipelines along high-throughput fuel corridors can alleviate demand for rail, barge, and truck transportation. Pipelines have a very different externality profile than other freight transportation modes due to differences in construction, operation, and maintenance requirements; labor, energy, and material input intensity; location and profile of emissions from operations; and frequency and magnitude of environmental and safety incidents. Therefore, public policy makers have a strong justification to influence the economic viability of pipelines. We use data from prior literature and U.S. government statistics to estimate environmental, public health, and safety characterization factors for pipelines and other modes. In 2008, two pipeline companies proposed the construction of an ethanol pipeline from the Midwest to Northeast United States. This proposed project informs our case study of a 2735-km $3.5 billion pipeline (2009 USD), for which we evaluate potential long-term societal impacts including life-cycle costs, greenhouse gas emissions, employment, injuries, fatalities, and public health impacts. Although it may take decades to break even economically, and would result in lower cumulative employment, such a pipeline would likely have fewer safety incidents, pollution emissions, and health damages than the alternative multimodal system in less than ten years; these results stand even if comparing future cleaner ground transport modes to a pipeline that utilizes electricity produced from coal

  20. Hydrogen Fueled Hybrid Solid Oxide Fuel Cell-Gas Turbine (SOFC-GT) System for Long-Haul Rail Application

    Science.gov (United States)

    Chow, Justin Jeff

    Freight movement of goods is the artery for America's economic health. Long-haul rail is the premier mode of transport on a ton-mile basis. Concerns regarding greenhouse gas and criteria pollutant emissions, however, have motivated the creation of annually increasing locomotive emissions standards. Health issues from diesel particulate matter, especially near rail yards, have also been on the rise. These factors and the potential to raise conventional diesel-electric locomotive performance warrants the investigation of using future fuels in a more efficient system for locomotive application. This research evaluates the dynamic performance of a Solid Oxide Fuel Cell-Gas Turbine (SOFC-GT) Hybrid system operating on hydrogen fuel to power a locomotive over a rail path starting from the Port of Los Angeles and ending in the City of Barstow. Physical constraints, representative locomotive operation logic, and basic design are used from a previous feasibility study and simulations are performed in the MATLAB Simulink environment. In-house controls are adapted to and expanded upon. Results indicate high fuel-to-electricity efficiencies of at least 54% compared to a conventional diesel-electric locomotive efficiency of 35%. Incorporation of properly calibrated feedback and feed-forward controls enables substantial load following of difficult transients that result from train kinematics while maintaining turbomachinery operating requirements and suppressing thermal stresses in the fuel cell stack. The power split between the SOFC and gas turbine is deduced to be a deterministic factor in the balance between capital and operational costs. Using hydrogen results in no emissions if renewable and offers a potential of 24.2% fuel energy savings for the rail industry.

  2. Identification and prioritization of rail squat defects in the field using rail magnetisation technology

    Science.gov (United States)

    Kaewunruen, Sakdirat

    2015-04-01

    Inevitably, rail squats and studs are continuing to be a serious problem for railway organisations around the world in the 21st century. They are typically classified as the growth of any cracks that have grown longitudinally through the subsurface and some of the cracks propagating to the bottom of rails transversely, and have branched from initial longitudinal cracks with a depression of rail surface. The horizontal crack, which results in a depression of rail surface, induces increased maintenance level, more frequent monitoring, compromised rail testing (as the crack shields the signal echoes), and possible broken rails. This paper presents field investigations using a magnetised-rail testing device developed by MRX Technologies to identify and prioritise the rail squats. Most of the in situ squats were found on the high rail of the transition (variable-radius curved track), which is associated with rolling contact fatigue (RCF). This investigation highlights the field performance of the MRX's surface crack detection technology in comparison with the traditional ultrasonic method and detailed walking inspection. Visually, it was found in the field that the size of the RCF squats varies from very small to moderate. The predicted crack data were obtained by scanning the magnitised rails. The comparison of the actual crack depths (ultrasonic) and the predicted crack depths (MRX device) shows: • A possible correlation for small RCF/ squat cracks. • Poor interpretation of larger defects and welds. The field assessment also suggests some practical issues required for further development, including the detection of rail spalling, deep transverse crack, welding, and so on.

  3. The rail abandonment process: A southern perspective

    International Nuclear Information System (INIS)

    1988-12-01

    One factor in evaluating the desirability of rail transport for high-level radioactive wastes or spent fuels is the frequency, or lack thereof, with which railroad and railroad lines have been, and are, abandoned. If DOE makes a decision to use the rail option and a line is subsequently abandoned, the choice results in increased cost, time delays and possibly safety problems: Information is therefore needed prior to the decision-making process to evaluate the desirability of the rail shipping option. One result of the abandonments mentioned herein, as well as other later abandonments, is the creation of a US rail system undergoing an evolutionary process in the 1980s as far-reaching as the changes that occurred when the industry was in its infancy a century and-a-half ago. The purpose of this paper is to examine the factors leading to some of these changes by tracing the historical development of the rail abandonment process, with particular emphasis on the rise of regional railroads, their problems in the modern era and current trends in rail abandonments as well as their effects on the southeastern United States

Les acteurs économiques des territoires desservis attendent beaucoup de cette arrivée notamment en matière de développement des tourismes urbain et d’affaires. Mais un tel développement n’est pas automatique. C’est l’appropriation collective de l’innovation que constitue la desserte à grande vitesse dans un territoire qui est au coeur de ses effets positifs. En effet, cette appropriation collective constitue une innovation relationnelle de laquelle peuvent naître des innovations de services complémentaires en matière de tourisme susceptibles de valoriser les ressources spécifiques existantes (patrimoine historique, culturel, gastronomique, etc.. Ainsi, si l’existence de ressources spécifiques joue un rôle pour les villes desservies, les efforts coordonnés des acteurs pour favoriser la “mise en tourisme” de la ville sont également décisifs. L’analyse est illustrée par le cas de l’agglomération rémoise.The East European High-Speed Rail started on June 10, 2007. Economic actors of beneficiary territories are expecting a lot of positive effects such as the development of urban and business tourisms. But such development is not automatic. The collective appropriation of the innovations linked to a High-Speed Rail Service seems to be central for generating positive effects. Indeed, this collective appropriation constitutes a relational innovation, which may give birth to additional services innovations in tourism that could enhance the value of existing specific resources (historical, cultural, gastronomic, etc. and turn them into assets. Thus, if the availability of specific resources plays a specific role for the connected cities, coordinated efforts of actors to promote the tourist development of the city are also decisive. We will illustrate our subject with the case of Rheims.

    Full Text Available Development of mixed transportation is a prospective direction of development of the transportation system of Ukraine. The article analyses the modern state of development of mixed transportation of freight in Ukraine. The most popular types of combined transportation (refers to multi-modal are container and contrailer trains, which are formed both in Ukraine (Viking and Yaroslav and in other countries, first of all, Belarus (Zubr. One of the reasons of underdevelopment of mixed transportation of freight in Ukraine is absence of a developed network of transportation and logistic centres. The article offers to form a network of transportation and logistic centres in Ukraine as a way of intensification of development of mixed transportations of freight, since they facilitate co-ordination of use of various types of transport and support integrated management of material flows. Transportation and logistic centres should become a start-up complex, around which transportation and logistic clusters would be gradually formed. Transportation and logistic clusters is a new efficient form of network organisation and management of transportation and logistic services and they also ensure growth of efficiency of use of the regional transportation and logistic potential of Ukraine. The article shows prospective supporting transportation and logistic centres and centres of formation of transportation and logistic clusters in the territory of Ukraine. Formation of efficient transportation and logistic system of Ukraine on the basis of a network of transportation and logistic clusters would facilitate entering of Ukraine into the world transportation environment and would allow acceleration of introduction of efficient logistic schemes of freight delivery, in particular, mixed transportation of freight.

    Full Text Available At present time freight stations operation is complicated by raised dynamics of production and transport processes. Under the given handling capacity, this circumstance affects duration of processing of inbound and internal flow of freight cars. In connection with the abovementioned, the article covers new approaches to the analysis and evaluation of operating characteristics, and designing of railway freight stations within industrial enterprises. These approaches base on the system adaptation of the railway freight stations structural layouts and parameters of technical facilities to new working conditions and production demands. As the criterion of optimization of freight station operation, the index of “transportation work” (freight car-hour was offered. It allows differentiating the elemental flows of freight cars from the overall flow of freight cars at the freight station. It also allows identifying structure, volumes and other parameters of train operation (duration of processing measured in freight car-hours, interpretational and technological idle time denoting the location and the reason for their occurrence. Moreover, the analysis and evaluation of yard operation is offered to be carried out via handling capacity balance, which illustrates the relation between the overall volume of transportation work and the amount of trains handled at the station. This allows establishing additional transportation work and makes it possible to evaluate the real (objective necessity in throughput and handling capacity of station facilities in particular, and the station in general. The operating characteristics that have been examined determine the new methodical approaches to designing of composition-and-structural layouts and parameters of industrial freight stations. As the basis for optimization of the station, the certain method of morphological analysis and synthesis of technical decisions can be accepted, with its modification due to the

    Jezzini-Aouad, M.; Flahaut, P.; Hariri, S.; Winiar, L.

    2010-06-01

    Rail transport development offers economic and ecological interests. Nevertheless, it requires heavy investments in rolling material and infrastructure. To be competitive, this transportation means must rely on safe and reliable infrastructure, which requires optimization of all implemented techniques and structure. Rail thermite (or aluminothermic) welding is widely used within the railway industry for in-track welding during re-rail and defect replacement. The process provides numerous advantages against other welding technology commonly used. Obviously, future demands on train traffic are heavier axle loads, higher train speeds and increased traffic density. Thus, a new enhanced weld should be developed to prevent accidents due to fracture of welds and to lower maintenance costs. In order to improve such assembly process, a detailed metallurgical study coupled to a thermomechanical modelling of the phenomena involved in the thermite welding process is carried out. Obtained data enables us to develop a new improved thermite weld (type A). This joint is made by modifying the routinely specified procedure (type B) used in a railway rail by a standard gap alumino-thermic weld. Joints of type A and B are tested and compared. Based on experimental temperature measurements, a finite element analysis is used to calculate the thermal residual stresses induced. In the vicinity of the weld, the residual stress patterns depend on the thermal conditions during welding as it also shown by litterature [1, 2]. In parallel, X-Ray diffraction has been used to map the residual stress field that is generated in welded rail of types A and B. Their effect on fatigue crack growth in rail welds is studied. An experimental study based on fatigue tests of rails welded by conventional and improved processes adjudicates on the new advances and results will be shown.

    Full Text Available Purpose. The paper is devoted to the study and evaluation of residual life for defective rails P50 operated on the roads of the Kyiv subway, which are taken out of service because of defects 11.1-2 on the side of the rolling surface of the rail head. Methodology. The studies were performed with the use of experimental methods: testing of samples of defective rails in the cyclical strength of the pulse machine and testing of defective rails in the static load limit on the hydraulic vertical press. Findings. The performed experiments indicate that on the tests basis in 2 million cycles is only a small development (increase in size 0.5-0.7 mm of existing code defects 11.2 as a result of shedding the particles of crumble out metal on the side of the rails head of working prototypes. The intensity and the catastrophic development of defects, such as 11.2, or transformation of these defects in defects such as 21.2 or 30G.2 did not happen in any case. Originality. For the first time in Ukraine with the theoretical calculations substantiated the greater possibility of defects formation of contact fatigue origin in the form of spall and jag of metal on the surface of the rail, at the edge of the head. It is the result of the creation of a high degree of stress nonequilibrium compression in this area, due to the high values of principal normal stresses and appearance of large shear stresses in the body of the head at a depth of 2.5-3.5 mm, exceeding the yield strength and metal endurance. The tests of experimental prototypes of defective rails on high cycle endurance (based № = 2,1h10 cycles with periodic defectoscopic control were conducted. Practical value. In experiments, the new data of the resistance ability to spall rail defects on the surface of the head of rolling on the code 11.1-2 long-term cyclic loading equal to operational magnitude at the wheel load test of 2 million cycles was obtained. That is, the defective rails can have residual life

    2017-03-01

    Full Text Available The fast-paced and ever changing freight market compels maritime executives to use sound forecasting tools. This paper aims to enhance the forecasting accuracy of the Baltic Dry Index (BDI by means of developing a multivariate Vector Autoregressive model with exogenous variables (VARX. The proposed model incorporates the Chinese steel production, the dry bulk fleet development and a new composite indicator, the Dry Bulk Economic Climate Index (DBECI. The predictive power of this approach is evaluated against a univariate ARIMA framework, which serves as a benchmark model. The selection of explanatory variables and the model specification are validated using a series of pertinent tests. The results demonstrate that the VARX model outperforms the ARIMA approach, suggesting that the selected independent variables can substantially improve the accuracy of BDI forecasts. The present study is of interest to maritime practitioners, as it provides useful insights into the direction of the freight market and allows them to make informed decisions.

    Full Text Available Currently Jakarta has two freight terminals, namely Pulo Gebang and Tanah Merdeka. But, both terminals are just functioned for parking and have not been utilized properly yet, e.g. for consolidation. Goods consolidation, which is usually performed in distribution terminal, may reduce number of freight flow within the city. This paper is aimed to determine the best location of distribution terminal in Jakarta among those two terminals and two additional alternative sites, namely Lodan and Rawa Buaya. It is initialized by the identification of important factors that affect the location selection. It is carried out by Likert analysis through the questionnaires distributed to logistics firms. The best location is determined by applying Overlay Analysis using ArcGIS 9.2. Four grid maps are produced to represent the accessibility, cost, time, and environment factors as the important factors of location. The result shows that the ranking from the best is; Lodan, Tanah Merdeka, Pulo Gebang, and Rawa Buaya.

  1. Determination of the primary technical parameters of the test bench for controlling the temperature of rails and rail bars of continuous welded rail

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available One of the most important factors determining the reliability and safety of operation of the continuous welded rail track is the temperature of the rails. All conditions of laying, repair and maintenance of the track during the entire cycle of rails operation depend on it. The existing rail temperature monitoring method does not take into account a few significant factors and that leads to significant errors in determining the actual temperature of the rail bar. The authors propose a new rail temperature measurement method on a special test bench which maximally simulates possible environmental operating conditions for the rail bars, the profile of the roadway (embankment or cut, as well as the actual spatial latitude and meridian location of the rail slabs. At the bench, the studied rails are fastened with the help of rail braces on half ties, in the ballast bed, with sizes in accordance with the existing reference documents. At the first stage, the most common KB-65 intermediate fastener for the continuous welded rail in Ukraine will be used, while in subsequent stages KPP-5 fastening will be used.

  2. Station Stopping of Freight Trains with Pneumatic Braking

    OpenAIRE

    2014-01-01

    In Chinese mainline railway, freight trains need to stop within passenger stations at times because of the delayed passenger trains. Without any decision-support system, it is very difficult for drivers to stop trains within stations with consistency in one braking action. The reasons are that braking performance of train changes with the conditions of braking equipment and the drivers’ subjective evaluations of track profiles and braking distance are vague and imprecise. This paper presents ...

  5. Structural response of a rail acceleration

    International Nuclear Information System (INIS)

    Wang, S.Y.

    1984-01-01

    The transient response of a 0.4 by 0.6 cm rectangular bore rail accelerator was analyzed by a three dimensional finite element code. The copper rail deflected to a peak value of 0.08 mm in compression and then oscillated at an amplitude of 0.02 mm. Simultaneously the insulating side wall of glass fabric base, epoxy resin laminate (G-10) was compressed to a peak value of 0.13 mm and rebounded to a steady state in extension. Projectile pinch or blowby due to the rail extension or compression, respectively, can be identified by examining the time history of the rail displacement. The effect of blowby was most significant at the side wall characterized by mm size displacement in compression. Dynamic stress calculations indicate that the G-10 supporting material behind the rail is subjected to over 21 MPa at which the G-10 could fail if the laminate was not carefully oriented. Results for a polycarbonate resin (Lexan) side wall show much larger displacements and stresses than for G-10. The tradeoff between the transparency of Lexan and the mechanical strength of G-10 for sidewall material is obvious. Displacement calculations from the modal method are smaller than the results from the direct integration method by almost an order of magnitude, because the high frequency effect is neglected. 12 references

  6. Hard-driven rail-gun tests

    1983-01-01

    A number of prototype rail-gun designs have been tested, powered by explosive magnetic flux compression generators. Peak currents as high as 1.3 MA were delivered. Rail guns with 50-mm-thick Kevlar fiberwound structural shells were able to survive these high currents with minimum mechanical damage and were refired after enlarging the bores 0.2 to 0.4 mm to remove arc damage. In some tests, mechanical damage occurred that was apparently caused by the rebound of the gun after firing. Although the Kevlar shells had more than adequate strength, they appeared to lack sufficient stiffness, allowing excessive deflections. The use of a steel structural shell with a Kevlar sleeve was an improvement. Intrusion into the seams of the rail guns and condensation of material from the plasma armature were observed. Improved sealing of seams is indicated. In some cases, we suspect maldistribution of current within the gun; that is, not all the current delivered to the breech of the gun seemed to reach the plasma armature. Experiments are being designed to quantify the effects discussed. Rail guns of advanced design are being fabricated. An 18-g titanium projectile was accelerated to 2.4 km/s in a 16-mm-round-bore, 0.6-m-long gun, 4-6 g polycarbonate projectiles were accelerated to 3.5 km/s in 13-mm-square-bore, 1.2-m-long rail guns. All tests were conducted at atmospheric pressure

  7. The literature of the California black rail

    1974-01-01

    Few birds have remained so little known as the California black rail (Laterallus jamaicensis coturniculus). Although first collected in 1859 or before and reported in 1874 (Ridgway 1874), its life history, distribution, and status have remained so obscure that even a sight record of the bird is deemed worthy of a report in some ornithological publications. Because degradation and loss of freshwater and saltwater marshlands in California may be detrimentally affecting the black rail, both the U.S. Bureau of Sport Fisheries and Wildlife (1973) and the California Department of Fish and Game (1972) have classified it as rare and worthy of further study. The 84 papers and notes both summarized in this report and included in its bibliography include essentially all that is currently known about the California black rail. Only 11 of these papers consider the life history of this rail in any detail. The rest are distribution notes and some of the more important papers on the closely related eastern black rail (L. j. jamaicensis). The latter are included for comparative purposes, or because they may lend clues to currently unknown facets of the life history of the western race.

  15. Why does the energy intensity of freight transport rise?

    Energy Technology Data Exchange (ETDEWEB)

    Scheele, D [Scientific Council for Government Policy (Netherlands)

    1996-12-01

    In advanced economies it is normal to observe declining energy intensities. Both improvements in conversion efficiency and in organisational efficiency of energy use cause energy demand to grow at a slower pace than the economy. In this context it is somewhat particular that in the vital sector of freight transport the energy intensity does not decline, but instead increases. The energy demand of this sector only takes a small share of the total energy demand. According to the World Energy Council the transport sector takes 30 percent of world energy demand and freight transport again takes 30 percent of the transport sector share, maritime transport excluded. Despite this small share some explanation is needed why the increase in energy demand form the volume growth of freight demand is not at least partly countered by a decline in the energy intensity. The purpose of this paper is to review some of the explanations that are given in the literature and to support these explanations with empirical evidence on the case of the Netherlands. (EG)

  16. Profile parameters of wheelset detection for high speed freight train

    Yang, Kai; Ma, Li; Gao, Xiaorong; Wang, Li

    2012-04-01

    Because of freight train, in China, transports goods on railway freight line throughout the country, it does not depart from or return to engine shed during a long phase, thus we cannot monitor the quality of wheel set effectively. This paper provides a system which uses leaser and high speed camera, applies no-contact light section technology to get precise wheel set profile parameters. The paper employs clamping-track method to avoid complex railway ballast modification project. And detailed descript an improved image-tracking algorithm to extract central line from profile curve. For getting one pixel width and continuous line of the profile curve, uses local gray maximum points as direction control points to direct tracking direction. The results based on practical experiment show the system adapted to detection environment of high speed and high vibration, and it can effectively detect the wheelset geometric parameters with high accuracy. The system fills the gaps in wheel set detection for freight train in main line and has an enlightening function on monitoring the quality of wheel set.

    Science.gov (United States)

    Balzer, Mark A.; Mungas, Greg S.; Peters, Gregory H.

    2010-01-01

    Non-lubricated ball bearings featuring rail races have been proposed for use in mechanisms that are required to function in the presence of mineral dust particles in very low-pressure, dry environments with extended life. Like a conventional ball bearing, the proposed bearing would include an inner and an outer ring separated by balls in rolling contact with the races. However, unlike a conventional ball bearing, the balls would not roll in semi-circular or gothic arch race grooves in the rings: instead, the races would be shaped to form two or more rails (see figure). During operation, the motion of the balls would push dust particles into the spaces between the rails where the particles could not generate rolling resistance for the balls

  1. Fast rail corrugation detection based on texture filtering

    Xiao, Jie; Lu, Kaixia

    2018-02-01

    The condition detection of rails in high-speed railway is one of the important means to ensure the safety of railway transportation. In order to replace the traditional manual inspection, save manpower and material resources, and improve the detection speed and accuracy, it is of great significance to develop a machine vision system for locating and identifying defects on rails automatically. Rail defects exhibit different properties and are divided into various categories related to the type and position of flaws on the rail. Several kinds of interrelated factors cause rail defects such as type of rail, construction conditions, and speed and/or frequency of trains using the rail. Rail corrugation is a particular kind of defects that produce an undulatory deformation on the rail heads. In high speed train, the corrugation induces harmful vibrations on wheels and its components and reduces the lifetime of rails. This type of defects should be detected to avoid rail fractures. In this paper, a novel method for fast rail corrugation detection based on texture filtering was proposed.
