The problem of the cylindrical compression wave propagation in an elastic medium is considered. The values of radial displacements of medium points and radial stresses are obtained. The asymptotic estimates of the obtained solutions for the displacement field in the medium at large distances from the wave sources are given, as well as the statistical distribution of the displacements of the medium.

A method for the centralization of existing diagnostic systems is proposed, it providing for the interconnection of information technologies for rolling stock monitoring. The author developed the diagnostic testing technology with the division of the most significant defects of rolling stock into classes according to the degree of responsibility.

The article deals with the problem of traction drive unit modernization of the TEP70 passenger locomotive. It is proposed to increase the drive reliability due to the application of hinges with rubber element cured to the inner bushing. As a further development of the drive, the authors recommended a design with the location of a small gear wheel between the rotor bearings of the traction motor.

To organize the transition to the maintenance and repair system of the traction rolling stock taking into account the actual state of units and units, it is necessary to widely introduce on-board, portable and stationary diagnostic tools with the formation of a data bank on the operating conditions of the elements and the locomotive as a whole. To solve these tasks, the author developed and tested an automated system for diagnosing the insulation of electric locomotive traction motors based on nano-interferometric optical fibre.

The article notes the importance of liquefied hydrocarbon gas transportation for the country's economy. The main characteristics of these gases are given. Some types of tank cars for railway transportation of liquefied gas are presented. It is significant the importance of modelling of thermal effect types on rolling stock. The natural conditions for this calculation were specified.

The issue of modelling of the object image blurring on the primary image in an automated system for monitoring and controlling of various categories of moving and stationary objects is considered. The blur function takes into account the value of the environment parameters between the monitoring system and the object under study, the colour components of the object image and background, the parameters of the object and detector movement, the parameters of detection tools and primary image processing.

The author considers one of the most important problems of the XXI century - the prevention and elimination of the epidemiological consequences at the railway facilities. To ensure personal hygiene safety, to clean the air from bacterial pollution and reduce infection with infectious diseases, it is necessary to introduce shower modules in passenger cars with a system of disinfection and decontamination after each passenger. In addition to the aerosol disinfection, the ultraviolet radiation should be used to enhance the decontamination effect.

The article presents the analysis and the ways to reduce the impact of the human factor at the workplace of a railway station master on duty.
V.E. Burak
The article analyzes the normative acts on the establishment of the sanitary protection zones and the possibility of the shift work within their borders. The author proposes a compensatory mechanism of free nutrition for working for a long time in conditions of constant exposure to noxious production factors of uncertain intensity.

The article deals with the problem of ensuring the comfort of railway passengers and train crews from vibration impact. The level of vibration acceleration increases as the stiffness rises from the nominal to the maximum value, causing the passenger discomfort and the occupational diseases of train crews.
O.S. Sachkova, A.M. Koroleva
The authors consider the professional activity features of the railway conductors. The working conditions of conductors are described. The effect of production factors on the professional morbidity level of conductors is shown.

Based on the conducted research, the article presents that the removal of graphite dust from the surfaces of internal production premises can be carried out using solutions of mineral acids. The results can be useful for the development of measures aimed at improving the working conditions of workers and reducing occupational traumatism.
E.A. Trifonova
The author gives the general characteristic of working conditions the physical and notes the emotional-mental loads of the penitentiary service employees. The article shows the classification of structural components of the labour process and working conditions of the employees of the penitentiary service (conductors, escorts). The technical characteristics of the passenger car of 61-4495 model for transportation of convicts and persons in custody are given.
