The main tasks of the railway industry are focused on reducing the costs associated with the operation and repair of technological equipment. It is possible to solve them by the development of technical means that optimally take into account the natural and climatic, geographical and technical operating conditions. In these operating conditions, the development of locomotive traction involves the modernization of the existing fleet of traction rolling stock, improvement of the locomotives produced, the development of a paradigm-shifting platform of lines of innovative locomotives, the replacement of equipment by more reliable and modern one, and the automation of processes. Automation makes it easier to control the locomotive, reduce the risk of errors and ensure the most rational equipment operation modes. It was found that the damage to the electric parts of the electric motors accounted for more than 70 percent of the total number of faults. The purpose of this article is to develop a technical solution, the use of which will minimize the number of failures of auxiliary machines and locomotive equipment of this series. To implement this, it considers the main design features of electric motors, their connection diagram and the presence of protection elements to determine the trouble spots and justify the proposed technical solution.

The minimization of the negative impact of the products of natural leaching of metal ores on the ecosystems of the environment is justified. It is shown that the reason for the formation of ore leaching solutions is the use of development technologies without filling voids. The results of observations are systematized and the concept of environmental management by combining the potentials of enterprises in the region is substantiated. The efficiency of using dolomite waste to reduce the leaching front by filling technological voids with dolomite-based mixtures is shown. The results of the study of the intensity and danger of natural leaching, taking into account the zoning of mineralization within the orefield, are presented. Measures to reduce the level of natural leaching are recommended. A leaching model is proposed that describes physicochemical processes as stages of reactions occurring in the ore mass. The algorithm of substantiation of environmental technologies is given. The ecological and economic criterion of the effectiveness of the implementation of environmental measures is proposed. The processes of natural leaching of metals are adequate, which makes it possible to control their development. Natural leaching is a consequence of the insufficient level of applied development technologies and can be minimized.

The need to strengthen the role of JSC Russian Railways in the processes of ensuring transport accessibility of the main energy deposits and energy platforms, including on the Arctic, Sakhalin and Caspian shelves. The industrial development of the Arctic involves the intensive exploitation of hydrocarbon resources, the extraction of biological resources and, as a consequence, the development of transport and transport infrastructure. The possibility of further economic growth in the northern territories is determined by such sustainability criteria as the economic growth of territorial economic systems and the system of indicators characterizing the concept of sustainability of economic growth in the production sector, in the financial, social and transport spheres. The article presents a forecast of multilateral accounting for the East Siberian Railway, when developing probabilistic scenarios for regional development, it implies a constant expansion and improvement of forecasting tools.
