Influence of technical and technological equipment of a locomotive maintenance point on the capacity of a railway line

Stable operation of railway transport is of decisive importance in the development of the country's economy. Railway stations of the Russian Railways network perform a significant amount of work on processing and handling train traffic. Large technical stations on the Russian Railways network in most cases are located at the junction of railways (railway polygons), where locomotive crews and locomotives changes take place as well as various types of traction (electrified lines with direct and alternating current). With the development of polygon technologies on the Russian Railways network, it becomes necessary to optimize the traction resource management process to ensure the stable operation of train traffic from its origin to the point of its destination. At technical stations with locomotive turnover points, they are changed, as well as maintenance (TO-2) and equipment. The article discusses in more detail one of the elements of the daily budget for the use of locomotives — finding locomotives in one of the types of downtime — at the locomotive maintenance point. As an example of the queuing of traction resources, the point of maintenance of locomotives of the Karymskaya station is given, where the stalls for performing TO-2 are one of the types of devices of the locomotive economy, according to which the available capacity of the locomotive circulation section is determined. Based on the analysis of the results of the operation of the locomotive maintenance point of the Karymskaya station for 2017, a method has been developed that allows, using in the calculations the minimum interval for the supply of trains to the station, to determine the rational number of stalls m ст , necessary for the development of promising volumes of freight transportation and increasing the capacity of railway lines.
