The subject of the research is a sub-rail foundation containing a viscous element. The purpose of the study is to evaluate the effect of including a viscous element in the elastic system (rails, sleepers, ballast, etc.) on the overall rigidity of a railway track. The design of a sub-rail foundation with a viscous element is described by the generalized Maxwell model and contains a shell filled with a Newtonian fluid, in particular air. Pneumatic shells with different thicknesses were considered. The modeling was carried out in the finite element analysis environment. Mathematical models of a track section with a sub-rail device containing a pneumatic shell were constructed. The calculation results showed the absence of a sharp increase in internal force factors and stress concentration in typical track sections when laying a sub-rail foundation with a pneumatic element. A change in the overall rigidity in the vertical plane did not lead to a significant change in bending stresses in the edges of the rails. With a small shell thickness, the bending stresses in the upper area of the sleeper decrease to 35 %, and in the lower area by 15 %. The maximum increase of up to 8 % is observed with a sharp difference in the shell thicknesses. Compressive stresses on the sleeper in the under-rail zone increase with a small shell thickness of the device due to the redistribution of forces to a smaller number of under-rail supports when the overall rigidity of the structure changes. Increasing the shell thickness to 40 cm leads to an increase in mechanical stresses of up to 20 %, which is an acceptable value with a large margin. The use of under-rail foundations with a viscous element is recommended for temporary railway tracks when laying them instead of ballast and sleepers, which allows for the track to be quickly laid and also quickly dismantled.

Explores the impact of truly existing longitudinal non-elastic railway track caused by the presence of sleepers and other factors on the vertical dynamic of vehicle. Formulas to determine the bounds of simple combinational and parametric resonances is obtained. Areas of dynamic instability of electric locomotive EP2K is builted.

The article deals with the issue of using electric power storage systems in railway transport. It is noted that they are used in renewable energy sources and on hybrid shunting diesel locomotives. The possibility of using electric power storage systems to improve the efficiency of using electric power for train traction is indicated. The introduction of electric energy storage systems in the traction power supply system is hampered by high capital costs and the need to strengthen several adjacent inter-substation zones at once. It is proposed to consider the possibility of creating a mobile energy storage system, all the equipment of which will be placed in containers installed on cargo platforms, which will allow such a system to be quickly moved. The purpose of introducing a mobile power storage system is to temporarily strengthen the traction power supply system during a planned overhaul or emergency repair of one of the tracks on double-track sections of the railway. In this case, there is a need for a batch pass of trains alternately in even and odd directions on the same track. The possibility of using a mobile energy storage system is considered on the example of a real section of the railway. For a given schedule of passing train packages, the dependence of the storage capacity taken off from time, the maximum power and the nominal effective energy intensity of the storage system are determined. An estimate of the electricity storage system cost is given. It is shown that more than 70 % of the total cost of the electricity storage system falls on the imported energy conversion subsystem. It is concluded that it is necessary to develop domestic converter subsystems.

The article discusses the urgent problem of upgrading non-public railway tracks through the introduction of automated loading and unloading control systems. The relevance of the study is due to the significant proportion of non-public tracks in the Russian railway infrastructure (29 % of the total length) and their constant increase, the growing volume of industrial production in the country and the need to improve the efficiency of transport services for enterprises and improve the efficiency of their use. More than 85 % of all freight traffic by rail starts and ends on non-public roads. The correctness of the service, organization and technology of the operation of the considered routes affects the operation of the entire transport network. The problem of the study lies in the fact that traditionally accepted methods of loading and unloading operations on non-public tracks do not provide the necessary efficiency of the transportation process, which leads to long downtime of rolling stock and increased operating costs for railway transport. The methods of system analysis, mathematical modeling and comparative analysis of statistical data are used in the work. Based on a study of international experience and domestic practice, it has been shown that the introduction of automated control systems can reduce the downtime of wagons by 25 - 30 % and reduce operating costs by 15 - 20 %. The article presents the definition of an automated loading and unloading management system as an integrated information management system that integrates hardware and software. A step-by-step methodology for system implementation has been developed, including seven consecutive stages from preliminary analysis to optimization and development. The proposed solutions take into account the specifics of Russian operating conditions and import substitution requirements.

To increase the level of mechanization and automation of the assembly processes of rail and sleepers, link assembly lines are installed at the production bases of the track machine stations. In 2012, a semi-automatic link assembly line of KB03 brand was introduced on the Belarusian Railways for the assembly of a rail-and-sleep grid on reinforced concrete sleepers with an SB-3 intermediate fastening. Increasing the productivity of this line is a priority area in research, since in modern conditions there is an increase in the volume of overdue railway track repairs. In the course of the study, it was determined that the most rational solution for studying the work of a link assembly line and finding ways to increase the productivity of its work is to use simulation tools. After studying the technical and other accompanying documentation, a simulation model of the KB03 assembly line was developed. Then the developed model was validated, during which it was found trustworthy and suitable for experiments. Based on the analysis of the results of the experiments carried out on the model, solutions were formed to control the production process of the KB03 assembly line to obtain the maximum increase in its productivity. The calculation of the economic feasibility of introducing the proposed changes and adjustments to the technological process of the link assembly line in production was carried out.

This article provides a detailed analysis of relevant issues related to improving the efficiency of freight operations with railcars at freight railway stations and the adjacent access tracks. The main focus is on reducing excessive idle time of railcars, trucks, and other rolling stock by optimizing the technological sequence of loading and unloading processes, as well as by rationalizing the use of technical equipment. The study substantiates the need to equip freight handling areas with a sufficient number of modern loading and unloading machines to ensure timely handling of cargo arriving in railcars of various categories. In accordance with the actual intensity of cargo flows, the most heavily loaded fronts located on critical paths are identified, and their optimal distribution is proposed, taking into account the quantity, performance, and workload of the technical resources in use. This systematic approach creates real preconditions for timely completion of all freight operations within the established timeframes, minimizes the risk of delays, and ensures a steady workflow at the station. The article also suggests ways to further improve the organization of local station operations through the development of a rational and balanced daily schedule. The use of network planning methods makes it possible to accurately identify critical operations, delays in which may cause schedule disruptions, and ensures reliable coordination of all stages of railcar handling. As a result, comprehensive improvements in the efficiency of freight station management and its operational performance are achieved. To prevent the idle time of transport vehicles during the delivery and removal of these railcars, it is advisable to carry out this process using Microsoft Project software for better organization.

The problem of the assessment of the continuous welded rail track stability at its thermal elongation is considered in this paper. The method for determining the stress-strain state of various elastic objects developed by the specialists of JSC “VNIKTI” is analyzed on the example of a rail of a continuous-welded track section. The essence of the method is to determine the dependence of the natural frequencies of rail vibrations on the applied longitudinal force. As a means of obtaining such a dependence, a modal analysis of a track section model carried out using the finite element method was chosen. The methodology for calculating the natural frequencies of rail vibrations and the description of the created model of the track section and its properties are presented in the paper, the contact interactions of the model elements and boundary conditions are defined in it. Calculations for determining the natural frequencies and modes of rail vibrations are performed, the first four modes of rail vibrations obtained by calculation and experimental methods are shown. The assessment of the adequacy of the created model of the track section is carried out by comparing the natural frequencies and modes of rail vibrations obtained by calculation, by modal analysis methods and experimentally when measuring vibrations on a full-scale object - assembled rails and sleepers, having a similar design compared with the model. It was decided to use the distance between the vibration nodes as a criterion for comparing the obtained modes of natural rail vibrations. The first mode of vibration is selected for further studies. Calculations were carried out and the dependence of the natural frequency of the first vibration mode of the rail on the longitudinal force applied to it was obtained using the created model of the track section. The obtained dependence can be used in the method proposed by the specialists of JSC “VNIKTI” in order to determine longitudinal force, applied to the rails on the full-scale section of the continuous welded rail track.

In this article, the problem of assessing the stability of a continuous welded rail track during its thermal elongation is considered. The article considers the method of determining a stress-strain state of continuous welded rails proposed by specialists of JSC “VNIKTI”, which is based on the use of the dependence of natural frequencies of rail vibrations on the applied longitudinal force. Such a dependence can be obtained with the help of the calculation method using a finite element model of a track section. The reliability of such a dependence can be assessed by comparing the results obtained using the calculation method with the actual values of natural frequencies of rail vibrations, depending on the longitudinal tensile and compression force applied to a full-scale facility. The track panel is chosen as such a facility. In order to obtain the actual dependence of natural frequencies of rail vibrations on the applied longitudinal force, a specialized test bench is developed. The development of the test bench included designing the test bench elements and creating finite element models of main load-bearing elements of the test bench - a stop, support and traction, as well as their subsequent strength calculation to confirm the operability of the selected design under necessary loading conditions. The strength is assessed using the safety factor for the yield strength. Calculations using the finite element method have shown that the test bench design has sufficient strength. The developed test bench will allow performing tests for the purpose of the verification obtained using the calculation method of the dependence of rail vibration frequencies on the longitudinal tension and compression force applied to it, as well as for testing the proposed method to assess the rail longitudinal force during its thermal expansion.

This article discusses the problem of loss of elastic properties of Pandrol Fastclip rail fasteners during operation. The research is related to predicting the dynamics of changes in the elastic properties of the Pandrol Fastclip clamping terminals during their long-term operation and provides for the creation of control methods (regulation) by pressing the fastening terminals on the sole of the rails, which guarantees the safety of trains with set speeds. On the basis of the conducted research, the design of a device that increases the pressing force of the fastening terminals on the sole of the rails has been developed. This device will provide optimal parameters for attaching rails to the sub-rail base at all stages of railway track operation. At the same time, there will be no need to replace the expensive imported elastic terminals of the Pandrol Fastclip fastening in cases of a decrease in the elasticity of the terminals in the current path. The research results are relevant for dozens of foreign railways where modifications of the Pandrol Fastclip fastener are operated: Pandrol Fastclip FC, Pandrol Fastclip FCA, Pandrol Fastclip FE, Pandrol 350, Pandrol SFC, Pandrol 1520, etc. The proposed technology for carrying out work to improve the technical condition of the intermediate rail fastening structure will not require the provision of "windows" in train schedules, which will not affect the carrying capacity and capacity of the railway track and will not affect the delays of scheduled trains.

In microprocessor automatic block signalling (ABS) systems all the basic functionality is implemented in software. Current technique used by Russian educational organisations for training of engineering staff is solely based on functionality exploration of the microprocessor ABS equipment. We suggest that this approach is not sufficiently effective and could be improved. In our view, the improvement could be achieved by addition of extensive ABS algorithm development practice to the Railway Signalling Engineering curriculum. In this article, we present a prototype of a special microprocessor learning board, which supports development and debugging of various ABS algorithms. Along with the functional diagram, we give some technical details and present preliminary results of implementing and using this prototype.

Based on the proposal for the formation of a railway track for operational deployment without ballast using a sub-rail base with a viscoelastic element forcedly filled with Newton's fluid and laid on an unprepared surface without ballast, an example of calculating the interaction of a wheel and a rail with this element based on the energy method is given. The possibility of using the design of the under-rail device for the operational laying of a railway track in difficult conditions on an unprepared surface without a track ballast layer is substantiated. The elastic dynamic impact of a wheel on a rail with initial speeds along a sub-rail base in the form of a box with shells laid on an unprepared surface is considered. The kinetic energy of a wheel hitting a rail laid on the proposed under-rail base passes not only into the potential energy of deformation, but also into the energy of wave and oscillatory processes. To improve the accuracy of solving the problem of dynamic impact, the transition of a part of the energy into the energy of local deformations in the contact area of the wheel with the rail is taken into account. Within a short period of time after touching the wheel at a certain speed, all elements of the rail acquire a certain strain rate. It is assumed that at the moment of contact with the wheel, the rail does not change its original shape, and the decrease in the speed of the wheel occurs due to local deformation of the materials of the contacting bodies; this period of impact will last until the velocities of the two bodies are equalized, after which the shape of the middle surface of the rail, modeled by a Bernoulli-Euler beam, will begin to change. Since the kinetic energy of the wheel is converted into the potential energy of bending, it is taken into account in the calculation to take into account the mass of the impacted body as the load of the wheel on the rail.
