Introduction. The article presents the results of a survey of employees of the railway industry and volunteers of various professions on their attitude to the possibility of employment of women as a locomotive driver and assistant driver. The aim of study is to determine the socio-psychological aspects of allowing women to work as a driver and assistant driver of an electric train among employees of various professions, including in the railway industry. Materials and methods. Anonymous online survey conducted among 112 people: 60 women aged 29.9±7.9 years (from 19 to 55 years), and 52 men aged 29.6±8.4 years (from 15 to 53 years). Results. There is an ambiguous attitude to the prospects of allowing women to work as a driver and assistant driver of an electric train. The most urgent problems of an organizational nature that accompany changes in labor legislation are noted: the abolition of allowances "for harm", the increase in the retirement age, inconveniences in holiday homes that are currently designed exclusively for men. There are also positive prospects for these changes: the possibility of healthy professional competition and the emergence of new areas of professional growth for women, as well as increasing the prestige of OAS "Russian Railways" by creating an image of a company that provides candidates with equal rights regardless of gender. Conclusions. The appearance (although it would be more accurate to say "return") of women to work as drivers and assistant drivers is not a forced measure, as it was in wartime, but the result of the modernization of rolling stock and railway infrastructure, bringing to the fore the assessment of professionally important operator qualities, regardless of the gender of candidates. However, gender characteristics cannot be ignored in the socio-psychological context - for example, when recruiting locomotive crews with mixed composition or when creating a favorable psychological climate in a locomotive depot.

The article presents the relevance of the topic associated with the introduction of technical diagnostics tools and the service system of electronic equipment for AC electric locomotives. Results of operating a microprocessor control system and diagnostics of AC electric locomotives on the Eastern operational area are presented in the form of failure statistics of elements of microprocessor technology. Structure of the technological process of servicing AC electric locomotives on the railways of the Eastern operational area is shown. Authors revealed features of building a system of locomotive maintenance points (LMP), which carry out repair and maintenance of electronic equipment for AC electric locomotives of various series. Functional scheme of the system for servicing electronic equipment for AC electric locomotives has been developed. Bench and technological equipment of the service area for the maintenance of electronic equipment is shown. The article describes development of an automated workplace (AWP) for optimization and repair of a microprocessor control system (MCS) for an electric locomotive, which was not previously in the locomotive sector. Examples of performing technological processes of repairing cassettes of MCS using AWP are given. The following conclusions were made: 1. Statistics of MCS failures and malfunctions of their cells on AC electric locomotives at the Eastern operational area for the period from 2016 to 2018 (LMP of station Tayshet and Karymskaya) shows that the number of failures of MCS decreased by 30 % and the number of malfunctioning MCS cells, received for repair, decreased by 45 %. 2. Automated workplaces created in the JSC “DTsV of the Krasnoyarskaya Railway” for optimizing and repairing the local government of AC electric locomotive made it possible to optimize repairs and create an automated process for the maintenance and repair of electronic equipment for electric locomotives. 3. Developed by specialists of the JSC “DTsV of the Krasnoyarskaya Railway” together with the employees of the LLC “Lokotech-Service” technological model of full service maintenance and repair of electronic equipment for AC electric locomotives on the railways of the Eastern operational area was implemented and well proved itself in the work of the LMP.

Digital transformation in the railway industry is an important element in the development of railways and should benefit commuters, railway operators, infrastructure managers and rolling stock manufacturers. The process of digitization applies to two domains, i.e. customer service and railway companies’ operation. This paper aims to present previous eff orts regarding the use of digital technologies in customer relations and in the field of operations and maintenance, which translates into the quality of services provided. This paper highlights important concepts of this domain with respect to passenger and freight transport, infrastructure, railway rolling stock and railway traffic management. It is also argued that the process of digitization needs properly trained staff . Examples of innovative initiatives of Polish and European railway companies are covered.

The paper analyzes the technological preparation of production at the railcar enterprises in terms of developing technological processes and processing sets of technological documents. Factors affecting the quality of technological preparation of production for maintenance and repair of rolling stock are considered. In contrast to the previously performed works, where the assessment of the level of technological training was carried out by experts of a scientific organization, the initial data in the article were the results of a survey of specialists of technical departments of structural divisions of the car industry of the Sverdlovsk and South Ural Railways. Based on the method of expert qualimetry, the weight of factors that have the greatest impact on the quality of technological processes is estimated. As a result of the survey, a low level of automation of design processes was established, which consists mainly in the design of technological documentation. It is shown that the degree of depth of development and detail of technological processes is at the level of the route description

Through additional processing of the modern movement parameter recorders data of the DC electric locomotive 2ES6 the article first presents the results of the actual consumption of electricity for own needs and the proportion of these costs from the consumption of trains traction is determined, which in terms of operational depot is difficult to implement. The estimation of influencing factors on the energy consumption for own needs of 2ES6 series electric locomotives is made. As a result it was found that the internal energy consumption is influenced by such factors as rolling stock mass, axle load and environment temperature. Statistic models were made to normalize internal electricity consumption and their quality estimation was fulfilled. It is found that the remainders of the multiple regression equation, which take the above factors into account, obey the normal distribution law, indicating the adequacy of their further use to assess the energy efficiency of the 2ES6 series DC electric locomotives auxiliary equipment. The use of regression models will allow to identify electric locomotives with auxiliary equipment with low energy efficiency and to send them to unscheduled repairs in time to restore the required technical condition.

The value of the life cycle of rolling stock wheels is determined by the frequency of maintenance, in the process of which the turning is carried out to restore the profiles of the rolling surfaces, or the replacement of completely worn wheels. Traffic safety depends on the technical condition of the wheels of locomotives and wagons. Maintenance and repair of wheelsets accounts for about 30% of all costs of Ukrzaliznytsia's rolling stock repair units. Wheel repair technologies are based on the complete restoration of wheel profiles by turning, using which, their life cycle is reduced, and costs increase by 20% or more. The railways of Ukraine use an outdated, unreasonable, inefficient system of control over the formation of rolling surfaces in operation. Therefore, there is a need to create a scientifically sound approach to methods of extending the life cycle of the wheels of locomotives and wagons while ensuring the safety of railway rolling stock. According to the proposed scientific approach, the wheel profile is restored to optimal parameters, which provides an extended life cycle of wheelsets. As a result of the developed scientific approach the life cycle of wheel pairs will increase by 15… 25% and the expenses of the railway for their repair will considerably decrease.
