Abstract:

An approach was proposed for determining rational parameters of the on-board capacitive energy storage for the underground railway rolling stock with recuperation systems. The essence of the approach is to determine the maximum power and energy intensity of the on-board CESS based on the analysis of the payback period of the storage systems. The main distinctive features of this approach include taking into account a number of operating conditions and technical features of the underground railway rolling stock. Using this approach, rational parameters of the on-board capacitive energy storage system for standard operating conditions of the experimental rolling stock with the recovery systems were determined at the Sviatoshyno ‒ Brovary line of the Kyiv Metropoliten. Based on the analysis of diagrams of the payback period of the chosen storage systems, it was established that for the given conditions of operation of the underground railway rolling stock, it is rational to introduce a capacitive storage with a maximum power of 1,000 kW and a working energy intensity of 3 kWh. It was calculated that for the given operating conditions, introduction of a storage system with rational parameters will save 16.1 % of the quantity of electric energy consumed for traction of the underground railway rolling stock

Abstract:

Purpose of the work: study of the formation of a complex air structure under conditions of rolling stock movement along extended underground structures using numerical modeling methods. Methods: an analysis of the influence of aerodynamic factors on rolling stock, passengers and railway infrastructure was carried out based on the finite element and volume method. The reasons for the occurrence of a compacted air zone, which appears in front of the head car of the train and exerts significant resistance to the movement of the train using the “Frozen Rotor” method, have been investigated. The indicators of energy efficiency and safety of the process of freight and passenger transportation are analyzed, taking into account the processes of aerodynamic interaction of moving rolling stock and artificial tunnel-type structures. Results: using numerical modeling and the use of the “Frozen Rotor” method, it was possible to obtain a qualitative picture of the distribution of transverse vortex air flows resulting from the occurrence of viscous friction. Regularities were discovered in the changes in the dynamics of pressure and speed of air masses on the surface of the head fairing when a train enters a tunnel. The fact of the negative impact of zones of high and low pressure, as well as their sharp drop, on the locomotive crew and passengers has been established. Practical significance: the possibility of conducting research in the field of aerodynamics of railway transport using modern numerical modeling methods is shown. This topic is very relevant in the field of designing high-speed rolling stock.

Abstract:

Although there is considerable engineering and demand planning analysis in the development of urban railways around the world, less attention is paid to the understanding of key operating conditions such as station stop times. The current paper takes forward research by London Underground, and shows that it is applicable to situations around the world without substantial changes in parameter values or the resulting passenger flow rates. Where passenger flow is substantially different, this can generally be explained by particular differences in the physical characteristics of the site, rolling stock, or passenger demand.

Abstract:

In recent decades, the use of constructed sleepers on the world's railways has been increasing: the United States, the EU countries, Japan and China. Such sleepers, having positive performance qualities of wooden sleepers (good elasticity and dielectric properties, manufacturability during laying and during repair work), do not have negative qualities of wood. The article reviews the US and EU standards for testing sleepers made of constructed materials. The classification of such sleepers is given. Examples of testing of such sleepers by specialists of JSC “VNIIZhT” for the period from 1999 to 2016 are given, including sleepers from modified wood, wooden sleepers with elastomeric coating, composite sleepers from recycled high-density polyethylene with glass-filled polymer. Features of the Russian requirements to the constructed sleepers are considered. Composite rail seat supports are promising in application. Possessing the advantages of wooden sleepers (bars), they have higher wear resistance, lower life cycle costs (recyclable), are more homogeneous and do not rot. Damping properties of composite sleepers contribute to solving the problem of reducing noise and vibration from rolling stock. In addition, their use is one of the ways to reduce the negative impact of rail transport on the environment. With a feasibility study, such sleepers will successfully replace other types of rail seat supports. Spheres of rational application of composite rail seat supports are heaving sections of the railway track, areas with weak soils, turnouts, tracks on bridges, railway tunnels, and underground tracks. Taking into account the tendency to expand the polygon for laying composite sleepers, including railway tracks, metro routes and land transport in the Russian Federation, Kazakhstan and other CIS countries, it is advisable to develop a single interstate standard containing safety requirements and test methods for constructed rail seat supports.

Abstract:

One of the main elements that shape the production process in an underground mining plant is, in the broadest sense of the word, transport. Currently, a large amount of rolling stock from cable cars or suspended railways is maintained in mining plants, along with extensive infrastructure used for transporting crew and materials. The development of conveyor belt transport systems, as well as system process management, is increasing efficiency levels. Mining transport is a complex process, requiring large amounts of energy, which incurs significant production costs. We conduct a comparative analysis of the human transport system using a suspended railway with belt transport at Lubelski Węgiel “Bogdanka” Spółka Akcyjna (the largest hard coal mine in Poland), in terms of energy efficiency levels. We found that the process of transporting the crew in an underground mining plant to the production site using a conveyor belt system was less energy-intensive, and therefore created less emissions than the currently used model based on suspended queues. The analyses for the above project were conducted according to a model that was based on the study and analysis phase of the project through to its implementation and transfer to operational activities. The analysis was carried out based on the created simulation model, taking into account all elements of the crew transport process to and from the mining area. The implementation of the technical solution allowed for nearly a threefold reduction in the level of energy consumption and emissivity. In the analyzed model, the energy consumption in the first phase of production was 3.04 kWh per employee using the diesel rails system and 1.13 per employee using the belt conveyor system.

Abstract:

Results of computer-aided studies of electromagnetic environment at railroad junctions of alternating current electrified railroads having voltage of 25 kV are presented. A large number of lines and overhead catenaries significantly complicate the picture of electromagnetic field distribution. The nature of the field distribution in space is significantly affected by the rolling stock on station tracks. Besides, the task of electromagnetic environment modeling is complicated by the presence of underground pipelines and enclosures, and reinforced concrete passenger platforms. During the transfer of power of 10 + j10 MV·A through the junction of overhead system, the magnetic field strength at a level of 1,8 m is considerably less than the magnetic strength at a railway haul due to current distribution on overhead system of several tracks. Magnetic field strength levels in calculation examples do not exceed amplitude of 30 A/m. The train performance leads to changes in the strengths of the electrical and magnetic fields. The dynamics of changes is presented as a result of simulation modeling of train movement modes.

Abstract:

Tunnels are an integral part of the ways and artificial constructions of the railway. Objective assessment of working conditions is important, because current regulations fail to allow to give a definite hygienic assessment of some factors of the production environment of the tunnels. Objective: to reveal the peculiarities of the formation of working conditions in railway tunnels with the subsequent hygienic assessment for the development of preventive measures. Measurement of the factors of working process and working environment is carried out with the use of the certified equipment for the approved the hygienic and sanitary-chemical methods in workplaces in tunnels of the East-Siberian railway. Specific conditions were shown to be formed due to constructive solutions, climate and geographical location, the length of railway tunnels, the composition of the rocks through which the tunnel, the nature of the maintenance tunnels, ventilation system, repetition rate and type of passing rolling stock. All employees from occupational groups from examined tunnels were established to be exposed to high concentrations of aerosols with predominantly fibrogenic action, noise levels, adverse climate (low positive and negative temperatures, high relative humidity and mobility of air), the lack of natural lighting, low levels of artificial light, hard exertion of labor (dynamic physical load, working position, the slopes of the body, movement in space). Additionally, high levels of the vibration, nonionizing and ionizing radiation were typical for jobs of the Baikal and the North-Muya tunnel. There is proposed the algorithm of hygienic assessment of the microclimate, light environment at the working places depending on the time of the works in the underground conditions and constructional features of tunnels, methods of accounting personnel dose rates from natural sources.

Abstract:

The article discusses the solution to the problem of underground railway transport slipping in dynamic modes, which occurs when there is a significant difference in the speeds of the driving and driven pairs of wheels. The state of the rail surfaces largely determines the coefficient of adhesion, therefore, using a mathematical model, the condition for the dependence of the magnitude of slipping and tractive effort is selected. For effective acceleration and deceleration of an electric locomotive, it is necessary to control the coefficient of adhesion at a certain level. A simulation model of rolling stock has been created, which for the first time takes into account a mechanical system with distributed parameters. In the structural diagram of the automatic control system of traction electric drives with frequency regulation, such factors as the volume of goods being moved, rolling friction, slope (rise) levels and the state of the rail track are taken into account. The simulation results show the features of the movement and stops of the freight train not only by the diagrams of speed and forces in the modes of acceleration-deceleration and uniform movement, but also the positions of the plungers and tractive forces on the couplings of the electric locomotive and all trolleys involved in the movement of goods. The practical application of the proposed method lies in the possibility of starting a heavily laden train from its place on the ascent section in conditions of insufficient adhesion coefficient with contaminated roads.

Abstract:

The analysis of the factors affecting the protective potential of a metal underground construction during the motion of the locomotive on the section is carried out. A graphical representation of the factors affecting the magnitude of the protective potential of the DF (drainage facility) of a MUC is given. The factors influencing the protective potential of the MUC when driving along the section of the West Siberian Railway are grouped. The first group of factors - the locomotive parameters - includes current, speed, mass, locomotive type, train formation and locomotive coordinate. By means of KORTES PC, the intervals of parameter changes are determined. The second is the track parameters, comprises the resistivity of the upper structure of a track (sleepers, ballast and roadbed) and the rail type. The third one is the resistance of the GA (grounding arrangement) of a MUC, the bedding depth of a MUC and the distance from the rails to the MUC. The fourth - the TS (traction substation) parameters include the coordinates of a TS and the DF of a TS, the distance from the rails to the GD of a TS, the resistance of the DF of a TS, the equivalent resistance of the GD of a TS. Also, the specific resistance of soil is attributed to the factors affecting the protective potential of a MUC. The results are summarized in a final chart of factors affecting the protective potential of a metal underground structure, taking into account the motion effect of an electric rolling stock on the section.

Abstract:

Abstract Every undertaking providing transport services in passenger rail transport must currently prepare for the liberalization of transport services operating under a public service obligation. Competition in the mentioned segment is expected to intensify. Rolling stock represents a significant cost item for railway operators. The management of the life cycle of railway rolling stock is a way to efficiently manage vehicles. Adequately chosen parameters that are monitored and evaluated during the life cycle of railway rolling stock are crucial to successful management. Logistics plays an important role in the railway vehicle life cycle management, which, when properly set up, represents a significant competitive advantage. All railway undertakings are facing challenging times due to the consequences of the COVID-19 pandemic and the energy crisis. Proper and effective railway rolling stock life cycle management will help them overcome current and future challenges.

Abstract:

Impact of the existing operating conditions on terms of cargo delivery and compliance with the rolling stock circulation norms is studied. Planned and actual rolling stock circulation characteristics are analyzed. Deviations from the norms have been detected, which is indicative of non-compliance with technological processes. Nowadays the rolling stock circulation problem becomes more complex; for the service recipients, i.e. customers of the railway, it means delays in cargo deliveries, non-fulfillment of financial obligations before other participants in the railway transport process. A new approach to the methodology and principle of calculating anticipated key performance characteristics are proposed. The existing information technologies for railway management make it possible to monitor compliance with the rolling stock circulation norms and the terms of cargo deliveries and to further improve methods and techniques of performance parameters. This will enable establishing realistic rolling stock circulation norms and cargo delivery terms, thus ensuring compliance with technological requirements of the railway transport processes in order to provide good customer service.

Abstract:

The application of a grid-characteristic method is proposed for numerical simulation of the movement of rolling stock along a railway track laid on an earth and a bridge. In the study, the railway track is presented using a dynamic system of equations of the theory of elasticity of hyperbolic type. The grid-characteristic method relies on the characteristic properties of the system under consideration and uses finite-difference schemes of high order of accuracy to obtain a space-time solution. The features of railway structures are considered by changing the boundary conditions and conditions at the contact borders. To simulate the areas of contact of wheel pairs of rolling stock with the rail – the "wheel-rail" system – a previously developed pressure boundary condition is applied, modified so as to consider multi-element rolling stock. As a result of computer simulation of the movement of rolling stock along the railway track of various types, full-wave stress distribution in the track structure is obtained, which makes it possible to predict dangerous sections of rolling stock movement.

Abstract:

Purpose: approaches to the maintenance of the railway track play a significant role in the interaction between the track and the rolling stock. The analysis [1–10] shows that existing methods for assessing the impact of rolling stock on the track have not completely resolved the issues of taking into account the residual deformation of the track, which does not allow us to have the most complete understanding of the ongoing interactions and processes between the railway track and the rolling stock in real operating conditions. In developing the issue of the need to take into account the residual deformation of the track, deviations in the geometry of the rail track in the profile, the article considers the “intrinsic” stresses in the track that are not under the influence of any load, arising as a result of the operation of a railway track with deviations in its contents. Methods: statistical analysis of the accumulation of residual deformations of a section of the railway track, review of existing methods for assessing the impact of rolling stock on the track, simulation modeling of the stress-strain state of the rail. Results: an analysis of the accumulation of residual deformations of a section of the railway track, a review of existing methods for assessing the impact of rolling stock on the track, modeling of the stress-strain state of a rail under load in two states (straight beam, curved beam) were carried out. Practical significance: the results can be applied when solving the problem of interaction between rolling stock and the railway track.

Abstract:

Currently, the economy of the Republic of Kazakhstan is adapted to market conditions. Therefore, the current stage of economic development in our country is accompanied by the construction of unique facilities. An example of this is the construction of modern railway tracks, unique bridge structures stretching for many kilometers, etc. The most common is rolling stock used in difficult natural and climatic conditions in various fields and industrial facilities, in the field of construction and utilities. The railway track and rolling stock represent a single thermodynamic system that interacts and depends on each other. The main task of studying dynamic processes in the Rolling Stock-Railway system is to determine the optimal values of this system (overall dimensions, weight, stiffness, coefficients of viscous friction, etc.), which reduce fluctuations and dynamic forces that negatively affect the reliability and strength of rolling stock and road structures.

Abstract:

Railway transit forms the backbone of sustainable transportation systems, which are necessary to limit the effects of global warming. In this paper, the authors seek to determine whether there is a statistically significant difference in energy consumption between distinct railway vehicle types. Firstly, the energy consumption measurement methods in the railway transportation sector are described and compared to each other in respect to precision and cost. Secondly, the use of energy consumption as a criterion in rolling stock tenders with the associated norm is analysed, particularly with regard to the life-cycle cost of railway vehicles. In the next part real life data on energy consumption of six distinct passenger electrical railway vehicle types is presented and analysed in order to compare the efficiency of different types of rolling stock. The differences in energy efficiency between rolling stock types may be used to improve the procurement process ensuring train operating companies obtain less energy-consuming vehicles.

Abstract:

The rolling stock might function at an optimum level in reliability, availability, maintainability, and safety with comprehensive maintenance. The past decade has seen rapid development in the management of maintenance costs in many sectors such as the automotive and aviation industry. However, there is a lack in a number of studies focusing on rolling stock maintenance costs. This article provides comprehensive knowledge on the rolling stock maintenance cost. Recently, the research found no specific literature reviews that focus on typical rolling stock maintenance costs. This paper attempts to review, identify and discuss the influential costs involved in rolling stock maintenance. This research systematically reviews and classifies a substantial number of published papers and suggests a classification of specific cost categories according to rolling stock needs. The results revealed that 27 variables have contributed to the rolling stock maintenance costs. The highest among the influential costs are 13.8% spare part cost, 11% life cycle cost, 6.4% preventive maintenance cost, and 4.6% for the workforce, corrective maintenance, and cost of ownership, respectively. The interrelationship between influential costs and their effects on rolling stock costs is further discussed. More importantly, the paper is intended to provide a comprehensive view of influential costs affecting rolling stock maintenance and give useful references for personnel working in the industry as well as researchers. This research has highlighted the possibility of future major studies to minimize the identified maintenance cost and industry to optimize its operational cost.

The present paper presents the rolling stock vibrodynamic impact model on railway pipelines, obtained on the basis of experimental studies conducted under field conditions at a railway station. The experimental research program provided for the determination of the effect of vibration-dynamic effects of rolling stock on the working condition of pipes and butt joints by conducting vibration-measuring work on the investigated section of the railway pipeline during the passage of various series of locomotives. The proposed modeling method makes it possible to obtain a correlation function of the oscillatory process of a railway pipeline, on the basis of which a spectral density is constructed to identify the amplitude-frequency range at which a stable resonance region occurs, leading to the destruction of the pipeline.

Abstract:

Rolling stock planning is one of the steps in the traffic planning process considered from the railway undertaking's point of view. It is directly related to the efficiency of rolling stock utilisation, which should be ensured at the highest possible level in the case of rail transport. The planning work stage is subject to certain risks (threats and opportunities), which, if they materialise, will impact it. It, therefore, makes sense to carry out analyses that can anticipate specific events in good time and introduce appropriate countermeasures in advance. This article aims to conduct a risk assessment process concerning rolling stock planning. It was assumed that the considerations were carried out based on the M_o_R (Management of Risk) methodology. Based on this methodology, risk identifica-tion and risk analysis (estimation of risk impact) were carried out. Risk assessment was carried out using the Monte Carlo simulation method. The work identified sixteen risks that represent threats. The principle of risk description was used to identify risks. It requires indicating for each risk the reason for its occurrence and the effect it may have. As a part of risk estimation, variables were selected to assess each risk's impact on the objectives of the stage. Publicly available statistical data were used to define the variables. The variables were expressed in monetary units. The work identified five variables describing impact, which were assigned to the individual risks. As a trian-gular probability distribution was used for the variability of impact description, the variable's minimum, most likely, and maximum value was identified. A risk assessment was carried out for only two impact description varia-bles (for those variables used to describe the impact of the most significant number of risks). For each variable, statistical parameters were indicated and analysed. The resulting value of the variable describing the impact was then read out for each percentile, and the expected value of the risk was calculated. A detailed risk assessment was made for the lower, middle and upper quartiles. A histogram of the incidence of each variable value was presented, and an assessment was made.

Abstract:

The article presents the content and results of a set of studies on the scientific and methodological support for the modernization of structures and devices built according to the old loading gauge standards or its expired durability, the entire 1520 (1524) mm gauge railway network under the loading gauge standard T for rolling stock, allowing to increase axle and running loads of cars and due to this — the mass of trains, as well as solve the global problem that arose in the middle of the last century to increase the efficiency of the most important branch of Russia — railway transport. Variants of increased loading gauges were developed (Тпр for any rolling stock, Тц for tanks, Та — for electric rolling stock, Тб — for passenger cars), which were included in the GOST 9238 – 83 “Loading gauges of railway rolling stock and structure clearance” and Ministry of railways instructions (no. TsP/4425 — for clearance of structures; no. TsV/4422 — for loading gauge of the rolling stock and no. TsD/4172 — for transportation of oversized and heavy (nonstandard) freights), as well as zonal and flatcars loading gauges. Scientific and methodological studies carried out by the institute during the half-century period (mid-XX — early XXI) identified structures and devices that limit the use of rolling stock of loading standard T, its elimination during 1982 – 2005, as well as transition of industrial enterprises to the production of new freight and passenger cars of increased loading standards Тпр and Та, developed by the Institute. This identification was made on the basis of the overall classification of all railway infrastructure and access railroads of the former USSR. New regulatory framework for railway rolling stock loading gauges and structure clearance (GOST 9238 – 2013) was developed based on a global survey of actual dimensions of all structures and infrastructure devices of the 1520 (1524) mm gauge railways (area 1520). Railway Research Institute of the Ministry of Railway Transport (currently, JSC “VNIIZhT”) made scientific and methodological support for the modernization of infrastructure objects, exhausted its life span for the 100-year period of operation. Scientific and methodological support carried out by the Institute allowed the creation and operation of rolling stock with an increased loading gauge standard Тпр: for freight traffic — with increased running loads by 2 ton/m or more compared to European railways; for passenger traffic — more comfortable and 39 % more spacious double-deck compartment cars. Increasing the loading gauge of the rolling stock provides increased efficiency of rail transport by increasing productivity, reducing the required fleet of cars for the transportation of equal volumes as well as operating costs. At the same time achieved annual total economic effect amounts to 2,205 billion rubles. Introduction of the flatcar loading gauge contributes to the organization of transportation of heavy trucks by rail and, therefore, improve the environmental situation.

PurposeThis paper proposes an approach for the development of a dynamic maintenance policy for the railway rolling stock system considering the dynamic characteristics of the system, the operation environment, and the maintenance process. The proposed approach can also be applied to other similar complex technical systems.Design/methodology/approachThis study explores the state-of-the-art in dynamic maintenance policy development for railway rolling stock to identify the research gap. The proposed approach is demonstrated through a case study on dynamic maintenance policy development for railway rolling stock maintenance support planning, emphasising constant assessment and improvement in the maintenance policy.FindingsThis study emphasises on the need for an effective, efficient, and dynamic maintenance policy that adapts to evolving system requirements such as organisational contexts, technological advancements, and regulatory requirements. This study finds that there are specific dynamic characteristics in each step of the maintenance policy development process. These dynamic characteristics are dependent on the changes in system requirements, the environment and in the maintenance process. The proposed approach for dynamic maintenance policy development provides a framework for the identification of these dynamic characteristics for different complex technical systems operating in a specific context.Originality/valueDespite the significant impact of railway rolling stock maintenance on railway system availability, research in this area is limited. The proposed approach for maintenance policy development for rolling stock integrates adaptability and responsiveness to dynamic factors in the maintenance process and the system requirements. Thus, the proposed approach provides a guide for industry professionals and directions for future research in dynamic maintenance policy development for other similar complex technical systems.

Abstract:

The paper presents results of research aimed at the application of axial fan for cooling friction band brake of railway rolling stock. The feature of the fan is the identical operation characteristics that don’t depend on direction of rolling stock movement. This is achieved due to special construction of blade system consisting of two mirror-placed grids located inside the brake wheel. Mathematical modeling of air flow in flow part of the proposed blade systems showed the reasonability of such solution. The paper shows results of calculation of blade system geometric and functional characteristics for friction band brake cooling fan designed for rolling stock with maximum speed up to 250 km/h. The proposed geometric form of blade system provides equal cooling efficiency regardless the direction of rolling stock movement.

Abstract:

Potential fire on board of the passenger train creates risk for passengers health and passengers life. Using non-flammable materials for producing Electric Multiple Units (EMUs) is not considered to be sufficient as passengers are carrying different types of materials as their luggage and belongings. In case of fire on board of the train, the EMU should stop in a place which is appropriate for passengers evacuation and fire fighting. Not all places along railway lines are considered to be appropriate for such purpose. Especially stopping in tunnels is considered inappropriate. Meanwhile the amount of tunnels on the Polish railway network is growing significantly. This requires application of the Technical Specification for Interoperability regarding Safety in Railway Tunnels (TSI SRT) and set of fire standards EN 45545. Using those requirements is associated with putting tunnels and rolling stock into service under railway interoperability directive 2008/57/WE. Additional analyse is however necessary from operational safety point of view due to growing amount of tunnels and growing diversity of rolling stock. Paper proposes conducting risk analyse in accordance with common safety method for risk evaluation and assessment based on a dedicated European Standard EN 50533 which defines requirements regarding running capability in case of fire on board of the rolling stock. Paper analyses applicability of that approach for group of tunnels and rolling stock fleet comprising different types of rolling stock including Electric Multiple Units.

The article highlights the development prospects and possible changes in traction rolling stock technologies in the coming years, as well as the problems that may arise as a result of advances in this area.Rail transport is a key aspect of the state economy. It is difficult to imagine a modern economic system without the railway industry. The presence of our own rolling stock production creates a solid foundation for the economy of any country.In Russia, rail transport became the basis for the industrial rise of the country in the late 19th century. It was the development of railway networks that contributed to a breakthrough in the economy, and also ensured the geopolitical interests of the country. This type of transport still plays an important role in the domestic economy. The modern national economy and its development prospects, the place of the state in the system of international relations largely depend on its functioning.Due to the noticeable increase in prices for energy resources, global manufacturers of traction rolling stock are forced to look for ways to optimize operating costs.The purpose of the study is to consider the need not only to optimally organize existing technologies, but also to adopt innovative solutions that will improve the position of rail transport.
