The article highlights effective measures of solving actual problems connected with brake lever transmission of freight wagon, namely purposeful transition to bogie braking and introduction of new system of uniform wear by making changes in the design of vertical lever of brake lever transmission.

Mathematical models are constructed in the finite element analysis environment of a typical railway track and a temporary railway track for operational deployment on sub-rail foundations with shell elements filled with Newton’s fluid with different filling levels.

 The problem of improving the performance of the TE26 diesel locomotive, created by JSC UK BMZ, is considered. A design of the traction motor suspension is proposed that does not contain wearing parts. The feasibility of creating a passenger version of the TE26 diesel locomotive to increase the degree of unification of the operated diesel locomotives is proven, which will improve the traction properties of passenger diesel locomotives by 14–22%. 

The article solves the problem of choosing the technology of wireless data transmission for the system of controlling the location of employees in hazardous areas in railway transport. Such technologies as Zigbee, Wi-Fi, Wi-Max, GSM/GPRS, 3G/4G/5G and LoRa are considered, their advantages and disadvantages are analysed and modulation methods of each of them are evaluated.

In order to implement projects for the development and formation of a modern transport infrastructure system on the territory of the Russian Federation, it is necessary to develop regulatory documentation that would take into account the strategy of interaction of various modes of transport at transport interchange hubs. The article discusses the advantages and features of developing such a strategy.

The article proposes a reduced search algorithm that significantly reduces the computational resources and calculation time for the number of undetected transformations of a cyclic code compared to the full search algorithm.

The purpose of the article is to synthesize the hierarchy of predictive analytics models implemented for objects and entities operating in Russian Railways. The synthesis of a semantic network of models, the apex of which is a meta-ontology based on ontologies of subject areas and applied ontologies applicable to railway transport, has been performed. Examples are given confirming the feasibility of the proposed hierarchy.

The procedure of creation and use of simulation model of wheelset repair process in depot conditions is described. The scheme of the simulated wheelset repair process created using basic blocks of AnyLogic environment is shown. The description and results of the optimisation experiment performed with the built model are presented.

The paper describes mathematical and information models of monitoring of cargo mass transported by railway transport, as well as methods of structural-algorithmic synthesis of decisions on the presence of commercial faults based on the results of weighing into a single macro system of intelligent commercial inspection (ASKM ICO).

The article examines issues of ensuring the security of intelligent water transport systems (IWTS) caused by non-physical threats, including imperfect regulations for the development and operation of IWTS, digital inequality of the elements of integrated automated systems for corporate and technological management of IWTS facilities, and insufficient development of domestic hardware and software platforms for IWTS.

One of the main elements of flight safety in civil aviation is the creation of flight safety management systems (FSMS). In accordance with ICAO and RF documents, FSMS should be developed for each type of flight support. Two options for developing FSMS are considered: for telecommunication flight support and for ornithological flight support.

The safety of the transport process is determined by the reliability of locomotive brigade workers. The research was carried out in the group of freight traffic drivers. The results allowed to establish that workers are not inclined to take risks, they have a high level of depersonalisation, formal performance of professional duties without personal involvement and empathy. This may affect the reliability of employees and corporate security.

 In the article the main stages of technological development of toilet systems in Russia and abroad are stated. The importance of using ecologically clean toilet complexes with bioreactor (ECTC) on railway rolling stock is noted. For the effective functioning of ECTC it is suggested to use biodegradable disinfectant with washing and deodorising action «BIODEZZHT». 

The article reflects the results of analytical review of data on cases of occupational diseases (OD), established at the workers of the repair and track complex for the period from 2009 to 2023. The information about working conditions, main harmful production factors affecting track workers is given, the data are compared with the structure of occupational diseases of the latter. Medical and organisational-technical measures aimed at preserving professionally significant functions of track workers are recommended.

The approaches to studying the influence of the human factor on the occurrence of industrial accidents in JSC Russian Railways presented in the article allow us to determine: the involvement of personnel involved in the labor process, their violations, groups of dangerous actions and the reasons for their occurrence. The analysis allows us to formulate an action plan for working with personnel and improving their occupational safety culture.

The article is devoted to the development of a mathematical model that allows obtaining predictive indicators of traffic safety at a single-level intersection of railway tracks with an automobile road, for the further construction of a priority series of crossings, from the point of view of the need for improvement or their additional equipment.

In the article the correlation dependence of the level of industrial traumatism and personnel turnover on the example of conductors of passenger cars is considered, the monitoring of the state of industrial traumatism, the analysis of the level of personnel turnover and personnel involvement is carried out.
