Operating efficiency of 3ES6 electric locomotives at the Ural-Siberian polygon

Background: developed economy requires an appropriate level of development of the transport system, it forms an important basis for the concentration and specialization of production. Consequently, the overall development of the regions and the country as a whole requires the development and modernization of the transport system, which has a direct impact on socio-economic development. In this regard, in order to solve the problems associated with increasing the efficiency of the transportation process in railway transport, it is necessary to introduce improved traction resources. Currently, Russian Railways is actively working to upgrade the corporate locomotive fleet and is addressing the issue of introducing high-capacity electric traction rolling stock, through the use of booster sections of electric locomotives, to drive trains of increased mass and length on strategically important railway sections of Russia integrated into international transport corridors. Aim: to develop a simulation model for the operation of 3ES6 electric locomotives with a booster section in the areas of the Ural-Siberian test site, to assess the readiness of the transport infrastructure when using the studied locomotives in train operation, to determine the most suitable traction arms for the operational operation of such electric locomotives. Materials and Methods: to obtain the results, the traction characteristics of the locomotives under consideration, data from the analysis of the traction arms of operation and transport infrastructure using the Yandex Maps navigation system, as well as Russian E2 software for creating graphic-physical 3D models with subsequent simulation, implemented in the Substance Painter and 3Ds software systems, are used max. Results: an analysis of the areas of operation of the studied locomotives is presented, indicating the advantages and disadvantages of using 3ES6 electric locomotives in the transportation process, a simulation model of the interaction of infrastructure facilities and the locomotive fleet is developed, the prospect of further research is determined in terms of carrying out calculations of a feasibility study for replacing the fleet of obsolete series locomotives. Conclusion: the obtained results of the study can be used in the organization of operational work and maintenance of 3ES6 locomotives with booster sections to improve the technology of operating a corporate locomotive fleet with a polygon structure for managing the transportation process.
