This article discusses the issues of eliminating defects in existing designs of locomotive traction motors. The authors present technical solutions to improve the reliability of traction engines by developing the cooling system.

As a result of the operation analysis of the Eastern Polygon section, an increase in the number of breaks in train schedules for the current track maintenance has been found. The reasons for the decrease in carrying capacity have been identified. The concept of the 'normal' mode of train driving is defined. The modelling was carried out using the Modelling of Stations and Sections Program. The article justifies the application rationality of the Automatic Locomotive Signalling System with Mobile Block Sections.

The article examines the features of the making up the local freight trains. The authors have carried out an analytical review of theoretical studies in the field of calculation, design, and application of shunting facilities to intensify the process of making up the local trains. The application of Dijkstra's algorithm is proposed for an alternative choice of location of a specialised marshalling station at the railway junction.

The article considers the class of systems with variable parameters, which also includes transport systems. An essential factor for the analysis of such nonstationary systems is the law of parameter variation, which reflects the nature, speed, frequency, and amplitude of parameter variation. The authors propose an approach based on the system definition by a linear differential equation with time-dependent variable coefficients.

An analysis of the reliability of the traction electric motors of electric locomotives of the Eastern Polygon is given. The reduced reliability of the insulation of the traction electric motors of VL85, 2ES5K, 3ES5K, and 4ES5K electric locomotives was established. It was revealed that the reason for the decrease in failure-free operation of traction electric motors is the transition from parallel ventilation, which provides the necessary heat output from the armature, main and additional poles, and compensation windings to non-parallel. A transition from non-parallel to parallel ventilation is proposed.

The article deals with the issue of incidents arising during the operation of railway transport and infrastructure. The incidents that lead to the loss of train-hours are called failures, and they are divided into three categories. The authors proposed a methodology for calculating the reliability indicators for failures of the third category, which makes it possible to assess the quality of the functioning of transport infrastructure facilities.

The authors consider the application of dimensionless and universal magnetic characteristics of diesel locomotive traction motors in the calculation of their traction and economic parameters.

The operating time service is more advanced than the calendar service. This type of service requires simple and reliable electronic time counters. One of the options for such a simple and informative counter is given in the article. Practical operation has shown the reliability and usability of such time counters.

The author analyses the quality of water from the water intake to the water and heat supply systems, as well as the possibility of reducing the corrosiveness of the liquid medium and the intensity of its scale formation by using crushed activated eco-friendly crystals.

This article is devoted to the creation and operation description of the subsystem for monitoring the sequential occupation and release of the coverage area of inductive loop sensors by motor transport in case of their unauthorised movement in a railway crossing. This control subsystem allows the timely transmission of relevant information to locomotive crews about approaching trains and reduces the emergency probability.

This article covers an important step in the processing of data from the Calipri-Ferberg CW-40 (CALIPRI), namely verification and preprocessing. This stage critically affects the quality of machine learning, since the accuracy of the data directly affects the analytical and model results. The main stages of data validation and preprocessing are discussed.

The article discusses a new technology for terminal processing of container traffic. This technology can be used for organising container trains in regional distribution and storage centers. The key problems and the need for scientific justification of new transport equipment (removable car bodies, interchangeable car bodies, and interchangeable motor vehicle bodies) are outlined.

Nowadays, suburbanised structures are being formed that have various geometric shapes. The article considers measures to attract passenger traffic through zones of ulterior flows. In these areas, special transport systems should be used, guaranteeing, on the one hand, convenience and comfort for passengers, and, on the other, efficient use of resources and reduction of service costs.

The article considers the control method of traffic lights standing at the entrance to the block section of the railway track, which record the moment the train arrives at this block section, if it is electrified. The authors propose a new solution for fixing the moment of arrival of the train on the stage by replacing the rail circuit as a source of information with an electromagnetic sensor located next to the contact wire in the area of the beginning of the block section.

The paper proposes a method for increasing the safety of rolling stock interaction due to the reduction of the fundamental tone of oscillation frequencies. The calculation of railway track vibrations at the increased speeds is given.

The article considers the prerequisites for the application of inspection control and technical audit as tools that ensure the safety of rolling stock for employees who operate and maintain it. The authors have identified directions to improve these tools in the context of science development and the range of materials used.

This article discusses the issues of ensuring environmental safety in the design of transport facilities. Particular attention is paid to the potential pollution of the environment with wastewater and the need for wastewater treatment in railway transport, depending on the source of their formation.
