The reduced reliability of insulation of traction motors of electric locomotives of the northern direction of the Eastern Polygon was established. It was revealed it is largely due to the irrational ventilation of the engines. The article considers the measures to reduce the insulation failures of traction motors.

The article analyses the efficiency of using vertical columns made of crushed stone in the areas of island permafrost distribution, the impact of this technology on the structure stability, and also considers the design of the embankment with different slope steepness and spacing of the columns.

When analysing the technical parameters of abroad trains, their maximum speed approaches 400 km/h, a tendency to reduce the weight of the locomotive underframe components was revealed, including the use of low-power traction motors, and the necessary traction power is achieved due to the complete motored axes of the electric train. To justify substantiate the feasibility of using this approach, the article carried out the computational investigation of the movement stability using the mathematical model of the Sapsan electric train at different weights and the design of suspending of traction motors on the bogie frame.

The article presents the research results of the approach intensity of passengers to boarding electric trains. It is determined that the approach intensity of passengers is described by the probability density function of the log-logistic distribution (the Fisk distribution), and that the key parameter affecting the distribution is the train-to-train interval before and after departure of the commuter electric train.

Based on the analysis of service equipment, the paper presents the impact of diagnostics on the adoption of predictive measures to identify technical malfunctions of passenger cars in 2021 and 2022. The authors consider technical means of collection and processing of measuring information used in diagnostics, and software for creation of dynamic monitoring system of passenger car.

Based on the use of a linearized model of locomotive wheelset spinning, the authors carried out a comparative analysis of the behaviour of the standard sand adding system under the wheels and the proposed adaptive sand control system in typical spinning cases. As the latter, the spinning cases during train acceleration and when running over oil spots on rails are used.

The article presents the functional model construction of the technological processes of repair and maintenance of railway rolling stock. This model construction is used in the technological design of objects and processes of railway car repair production. The authors describe the general technique of variant design.

The dynamics of the increase in the volume of cargo transported in the eastern direction requires the implementation of complex solutions to improve the traffic capacity of the transport and terminal logistics infrastructure. The authors carried out the assessment the workload of the border checkpoints of the Primorye-2 international transport corridor, in particular, the Makhalino (RF) - Hunchun (PRC) railway border crossing and the Kraskino automobile checkpoint.

The rail transport has a dual entity as a system and an element of the national economy system. In the second case, its function is to ensure the country economic connections with reliable and effective transport links. The formation of the structure should be considered from the functional positions. It is important to consider in infrastructure design and work organisation.

In this paper, the sequence of departure and arrival deviations at a station is considered as the Markov chain. Each link of this chain has a transient probability matrix the authors use to determine the efficiency index. Based on this numerical characteristic, a method for quality assessing of vehicle traffic control has been developed. Estimates obtained with the proposed method are shown to be consistent with those of another, earlier method.

The article describes the information model of the intelligent commercial inspection implemented as part of the automated system of operational control and quality analysis of commercial work and freight transportation safety (ASKM ICO), a formal recurrent model, the task decomposition tree, constructed according to the object-oriented and method-oriented principle, a description of methods of auto-diagnostics of the condition of rail cars and cargoes: weighing, infrared scanning, laser scanning, neural network photodiagnosis, temperature control and radio frequency control. The architecture of the developed system and the test results are also given.

The article describes the algorithm for acceptance tests of pneumatic spring suspension of double-decker passenger car bogies of the Carriage-2020 project. The methods of acceptance tests of pneumatic spring suspension of passenger cars of locomotive traction were developed and agreed upon. The tests were carried out in stationary conditions and on rail tracks.

Various approaches to detecting inorganic selenium in an aqueous medium using electrochemical methods have been studied. During the study, it was found that selenium does not precipitate on the surface of the graphite electrode if it is present in solutions. The effect of various parameters (background electrolyte content, pH, potential and accumulation time) on the selenide ion analytical signal was determined.

The article considers an approach to solve the behaviour problem forecasting over a certain time interval of the organism of a transport college student, with various factors and using data on his (her) initial state of health. The mathematical model of a person is used to solve this problem. The model is close to the real characteristics of the behaviour of the organism of the transport student. And this model is calculated numerically and analytically.

The authors consider the combined influence of the railway and thermal power plants on the distribution of heavy metals in the adjacent territories. The sources of heavy metals in the flying ash of the thermal power plant are presented. The contribution of enterprises to the pollution of soil in the wayside zone was assessed.

The author considers the issue of assessing the state of organism functional indicators of locomotive crew drivers under various weather conditions, stressful situations during labour activity. The paper identifies the indicators which can be used in determining the risk group among drivers in predicting emergency situations in railway transport.
