The article considers the prospects of using the hydrogen-powered rolling stock for railway transportation, including suburban and urban transportation. The effects of the introduction of hydrogen fuel cells into passenger and freight locomotives have been determined. The authors identify the most conforming scope of application for a new type of rolling stock.
A.E. Chekmarev, S.A. Vasiliev, A.N. Kuznetsova, A.V. Podorozhkina
The authors consider the possibilities of traffic capacity assessment of infrastructure elements of Moscow Central Circle transport hubs by means of a professional AnyLogic simulation package.

The article suggests the mathematical description of the being repaired railway cars and their elements used in the technological design of objects and processes of car repair production. The general technique of variant design is described; and the procedure groups, the information model structure and recurring design tasks are formalized.

Based on the assumption that the rail is an infinite string "adhered" to a rigid base, the task of this wave localizing is set and solved. The possibility of the rail track defect identification in the places of the string "detachment" is shown.
L.N. Loginova, D.A. Didushok
The authors have analysed and formulated the requirements for a unified testing system for operational workers of urban rail transport systems. On the basis of the IDEF0 methodology the article proposes the process modelling of knowledge testing of employees, as well as a graphic structural analysis of the being implemented system.

The article is devoted to the issue of optimal railway infrastructure development for the required traffic volumes. A polygon approach in engineering is proposed as a search problem solution of the optimal railway infrastructure development.
S.A. Sinitsyn
The author considers the theoretical bases of the information method of integral criteria for accuracy control of manufacturing of parts and elements of transport machines under conditions of using the serial technological equipment of continuous service. A feature of the method is the possibility of aggregate estimate of design parameters by measuring their systematic component in a variable uncertainty interval.
A.F. Bel'ts, L.Yu. Shevyryov, A.N. Kaplunov
The authors consider the necessity of teamwork optimization of harvesting and transport complexes on the example of JSC "Uchkhoz Zernovoe". The paper substantiates the economic effectiveness of teamwork optimization necessity.
O.N. Larin, A. Oyuungarav, D.A. Pribytkova, Ts. Moononhuu, S. Baasan
The article considers the design features of digital twins for monitoring business processes in supply chains. The authors propose to structure the information flow about the state of business processes in the links of the supply chain to obtain operational information about current outcomes and improve the forecast precision.
D.G. Evseev, A.S. Utkin
The authors consider and analyse the possibilities of reliability improvement of the brake system components, in particular, due to the development of the brake resistor unit, and the article justifies the option of its heating temperature reduction during operation.
M.V. Fufacheva, E.M. Lytkina
At present, more and more attention is paid to the digitalization of organization and operation of train traffic. The article discusses the method of introducing interval regulation of train operation in sections taking into account the number and capacity of the layout of intermediate and technical stations of the railway division.

The distribution of random deviation from the schedule when the train arrives at the terminus is obtained, a single-train stochastic model of train operation (introduced by the authors in the article in 2020) being used. The found distribution has an integral form and depends on the joint distribution of the deviation when departing from the penultimate station and the travel time from this station to the terminus.

An important role in the transportation process of the Moscow Metro is the equipment reliability of the operated cars. The condition of the motor-car rolling stock equipment directly affects the train movement safety and the same direction train interval because the equipment failure results in the unscheduled rolling stock repair and reducing the number of simultaneously operated trains on the line.
B.F. Bezrodny, L.V. Lyubimova
The authors consider the approach to technosphere safety protection in terms of reducing the risks of hazardous impacts on humans and the environment through cyber threats. The paper describes the method for quantitative efficiency estimation of strategies for protecting automated railway control systems from cyber threats.
V.A. Aksyonov, A.V. Kiselev, V.V. Samoilov, E.A. Kiseleva
The article considers the issues of personnel training in occupational safety, health and life protection at work, professional development and knowledge actualization of personnel working at the enterprise; in particular, it is proposed to use specialized GoContractor software which allows optimizing and simplifying safety training.
A.A. Kirillin, O.S. Sachkova, D.V. Klimova
The article is devoted to personal protective equipment for infrastructure complex employees involved in repair and construction work. An analysis of harmful and hazardous factors acting in the work area was carried out.
