Prospects for commissioning of the 2ES5K electric locomotive at the West Siberian Railway Poligon

Abstract

Railway transport is the undisputed leader in the transportation process in Russia. In modern realities, the issue of cargo transportation is strategically important, therefore, the railway industry is interested in changes that will contribute to the adaptation and operational restructuring of the transportation process under the influence of external factors on international transport corridors, a significant part of which runs through the territory of Russia. This article discusses the parameters and profiles of the railway sections of the Central Siberian course of the West Siberian Railway. The specific weight of light track elements with slopes in the range from -3 to +3 ‰ for traction arms with limiting slopes of the railway polygon under consideration is calculated. The paper presents the reasons that justify the need to update the corporate fleet of electric locomotives in the areas under consideration. The article presents a comparative analysis of the technical characteristics and overhaul periods of mainline freight electric locomotives of the ES5K series in comparison with the two-section electric locomotive VL80S. The results of traction calculations are presented to determine the required traction units for a given traction arm, on which it is supposed to put into operation the main freight electric locomotive of the ES5K series, taking into account pushing locomotives. The paper presents the results of calculating the required fleet of locomotives on the considered railway section. The calculation showed that new 2ES5K electric locomotives require 29 fewer locomotives compared to VL80S electric locomotives. Conclusions are drawn about the prospects for further research on the potential use of electric locomotives of the ES5K series in operation on sections of the West Siberian Railway electrified on alternating current.
