The issue was considered and the need to create a concept for an energy-efficient locomotive carriage was identified. The formulation of the concept and basic requirements are proposed. As an example of the concept implementation, it is recommended to use two-axle trolleys with a wheel diameter of 1250 mm in the carriage.

The article discusses the design of the heads of hydraulic vibration dampers of passenger cars with a detailed analysis of the materials used in the manufacture of bushings in the heads of dampers. Based on the analysis of the characteristics of these materials, as well as taking into account the aggressive environment in which the extinguisher operates, the main disadvantages of the materials used and the possibility of replacing them with more wear-resistant ones are identified.

It was found that the reliability of TED NB-418K6 anchors is 3.13 times higher than the reliability of TED NB-514 anchors. The reliability of the TED NB-418K6 is 2 times higher than that of the NB-514 engines. In this article, it is proposed to modernize TED NB-514, NB-514B, NB-514D and NB-514E electric locomotives VL85 and 2,3,4ES5K, taking into account the positive operating experience of TED NB-418K6.

The article discusses the features of failure analysis of locomotive components to assess their technical condition and repair. An approach based on the failure modes and consequences analysis method is described in order to identify and assess potential risks associated with failure of rolling stock components. The applied features of the method are considered on the example of failure of the locomotive braking system.

Some ways of information coupling of automated monitoring systems of railway infrastructure facilities with train traffic control systems are proposed. Information coupling is carried out through linking with railway automation and telemechanics systems and requires certification and proof of the safety of monitoring systems to use data on the condition of diagnostic facilities in the control loop.

The issues of the development of algorithmic and software for the automated assessment of the vibration effects of traffic flows on infrastructure facilities, performed on the basis of simulation modeling and expert knowledge, are considered. The features of the representation and integration of data from field measurements of vibrations are described using the example of vibration loads created by the movement of subway trains.

The article discusses the centralized management algorithms used on Chinese railways, the features of their models, taking into account the current restrictions. The features of the structure and the results of the application of an intelligent train traffic control system based on a centralized automated dispatch system are investigated.

The problem of structural imbalances arising at the design stage of railway stations and landfills is considered. The direct elimination of structural errors would require serious material costs. The authors propose a way to reduce the negative effects of imbalances by technological means. The experiments were carried out on a polygon model built using an IOMETER simulation system.

The results of the analysis of the statistics of occupational injuries in vehicles according to the data of the State Labor Inspectorate in the Moscow region are presented. An average model of the seasonal component of the time series and an age component model are constructed using the Excel software environment. The results can be used in carrying out control and supervisory measures to prevent and minimize accidents at work.
D.V. Klimova
The article describes a model for ensuring the safety of workers in the transport industry. The use of algorithms for dynamic analysis of data monitoring the working conditions of railway transport workers will expand the apparatus for assessing working conditions and conduct targeted formation of a system of preventive measures.

The results of a study of the state of actual nutrition and vitamin and mineral security of workers engaged in railway track repairs are presented. An imbalance of the diet in terms of basic nutrients has been established, a low quota of carbohydrates and a deficiency of essential vitamins have been identified. Taking into account the assessment of nutritional status, a nutrition program has been developed aimed at enriching the workers' diet with essential nutrients (vitamins and minerals), protecting the body from adverse production conditions, and improving working capacity.

The article discusses problematic issues arising in the treatment of surface wastewater during the construction and operation of railway facilities, and considers measures to reduce the negative impact on the environment.
D.V. Davydov
An overview of methods of disinfection of the air environment is presented. The analysis of the applicability of disinfection methods in ventilation and air conditioning systems of public transport is carried out, conclusions are drawn about the most effective and safe methods of disinfection of the air environment of vehicles.
