The article considers the research results of the carriage microclimate system in the cold period of the year, the air conditioner of the carriage climatic installation works in the thermal pump mode for the ventilation air heating. The air removed from the passenger car is used as the low-temperature heat source.

The prediction problem of passenger traffic is traditionally relevant for any mode of transport. The authors analyzed the main prediction models of rail and air passenger transportation. The paper summarizes the different approaches and carries out the assessment of the error and the usability conditions of different models.

The article focuses on the problems of unladen freight car traffic organization from the car receiving for transportation to its completion. The authors propose a new approach of unladen freight car traffic control in cooperation with the rolling stock operators, it reducing the company's costs for the unladen freight car traffic operation and improving the use of rolling stock owned by operator companies.

The authors studied a three-dimensional image of correspondence of the selected decomposition scheme of the specified solid cylinder into the equivalent plate. Temperature fields formed from the action of a moving point heat source on the surface of a given solid cylinder along a helical line of a given pitch and an equivalent plate are calculated depending on the depth of the layer under study.

The article considers the trends in the development of railway car dynamics. The main research schools of this branch of science are described. The paper presents an overview of the software used to solve dynamics problems. The authors summarize the approaches to computer simulation implementation.
A.F. Slutin, L.G. Ruchkina, V.A. Bugreev
The article presents the results of numerical simulation of traction and energy modes of hybrid electric bus movement based on the developed mathematical model and software. The authors propose the calculation methods and comparative technical and economic analysis in terms of operating costs for energy carriers and power supply systems for three types of modern ground public transport.
I.A. Zhuravlev, E.A. Zhuravleva
The article proposes an approach to the development of a decision support system (DSS) for the contractual and claim work of the enterprise. The authors present the structure with knowledge research domain particulars and the scheme at the base intelligent data analysis of the DSS of the company's contractual and claim work.

The article presents an analysis of the reference promising directions for the development of the labour safety control system in transport, taking into account the introduction of the concept of zero injuries.
V.A. Aksyonov, V.E. Burak, E.A. Sorokina
The combined effects of chemicals in the toxic emissions of different modes of transport in agglomerations can be taken into account during the special assessment of working conditions and industrial control by introducing an increasing coefficient into the calculation part of the measurement protocols.
V.V. Samoylov, O.S. Sachkova, V.I. Apattsev
The article focuses on the labour conditions of workers involved in bulk cargo transportation and ways of working condition improvement.
O.V. Voronov, V.V. Bykadorov, L.I. Tishchuk, E.I. Ivanova
The article presents the analysis of calculation regularities of contaminant dispersion in the atmospheric boundary layer taking into account peculiarities of their spatiotemporal distribution and the physical and mathematical modelling of contaminant diffusion processes of anthropogenic origin.
V.P. Sychev, A.V. Sycheva, P.F. Bestemyanov, V.N. Filippov
The article analyzes the normative documents of JSC "Russian Railways" for the impact of the railway track monitoring periodicity on the risk assessment and the level of injuries.
A.I. Shevchenko, V.V. Denisov
The article contains the analysis and assessment of fire safety with the risk management techniques at the facilities of JSC "Russian Railways" at year-end 2019.
E.A. Trifonova, B.N. Rakhmanov, V.N. Filippov
The article analyzes the working conditions of penitentiary service employees, the general description of working conditions and the components of the labour process. To improve the working conditions of penitentiary service employees the authors propose to reduce physical, emotional and mental stress, as well as to limit the effect of harmful factors by developing and implementing a new special passenger car.
