The article considers the influence of the mutual geometric position of the third and track rails on the operation of on-board equipment of automatic locomotive signalling in the underground. A model for calculating the asymmetry coefficient at the input of a locomotive receiver is described. The simulated results of for a single-track subway tunnel are appended.

The authors have established the intensive nature of the reducing the reliability of traction electric motors of VL80 and VL85 freight electric locomotives long-term operated on the railways of the Eastern Polygon and 2,3,4ES5K electric locomotives recently received from the manufacturing plant. This makes it possible to identify the weakest units of traction electric motors, the dominant cause for reducing their reliability, and to rationally manage the provision process of their maximum possible failure-free operation.

The authors present the research results with the probabilistic and statistical methods making possible to determine the distribution law for the geometric parameters of the car wheels. The expediency of determining the random distribution law is substantiated. A number of conditions the sample volume depends on are listed. The practical significance of the study is justified.

The authors analysed directions of existing studies in the field of reliability of main and distribution electric networks. Technical and organizational-technical aspects of power supply reliability improvement are considered. The classification of means of reliability improving the power supply for consumers is given. The factors affecting the reliability of power supply and the provision of resources at the enterprise have been studied.

The behaviour of the base plate of the ballastless track under dynamic impact has been simulated. It is this design that is currently one of the most promising. For this construction, a plate segment reinforcement scheme is being developed consisting of local meshes with circular rods under the rail support zone on an under rail base and a common volumetric frame calculated by traditional methods.

The article proposes the use of the decision tree method in the process of organizing of perishable freight transportation by land transport. The estimation of the technological potential of various types of isothermal vehicles was given. The authors justify and give arguments of the sequence of steps in the process of choosing the fleet composition of isothermal vehicles in the format of the decision tree method.

The authors consider the issue of efficiency increasing of finance investment in the railway infrastructure development. A new approach to the formation of an optimal list of measures for the infrastructure development and the selection of technical parameters of a new facility with the introduction of an algorithm for its implementation tested at a specific section is proposed.

Most vehicles are equipped with internal combustion engines which negatively affects the environmental situation. An alternative solution to this problem is the use of electric vehicles (EV). As a result, it becomes relevant to conduct studies to improve the EV operational properties. The paper considers the influence of the use of the gearbox in the EV transmission on its dynamic characteristic.

The article considers the issue of the reliability improvement of traction power supply systems from the position of relay protection operation. The authors carried out the analysis and have presented statistical data of the relay protection operation of the contact network feeders on the example of the Sokhondo traction substation of the Trans-Baikal Railway, a branch of JSC "Russian Railways". The most typical types of actuations have been identified.

The article justifies the need to develop and implement an intellectual system carrying out control and supervision activities at transport infrastructure facilities. The advantage of the proposed system is the ability to continuously analyse the events and the information output to specialists in real time.

The article presents the detailed analysis of the amount and causes of transport violations brought traffic safety violations as a result of professional activities of operational personnel for 2017-2021; the relevant classification has been performed.
A.R. Zakirova
The article discusses the problems of electromagnetic safety of personnel serving the electric rolling stock. It was established that the total power load levels in the cabins of the mainline electric rolling stock of direct current do not adversely affect the electrical personnel. The necessity to use the control devices of electric and magnetic fields of direct and alternating current in the electric rolling stock of alternating current is justified.

The paper has explored the relevance of Heinrich Herbert's Law that there is a direct link between accidents, minor injuries and dangerous situations. The necessity to investigate the microtrauma as one of the fundamental areas of prevention of occupational injuries in order to ensure the priority of preserving the life and health of workers is shown.
E.A. Arsentieva, O.V. Kanunnikov, D.V. Klimova
Parameters of traffic noise analysis are considered. The authors present the summarised analytical data of the research results of the noise pollution impact on public health are provided.
