Operational planning of a freight train locomotive fleet taking into account certain factors

   For the successful organization of the transportation process, it is necessary to ensure the rational use of traction resources. The size of the required fleet of freight locomotives is determined during the development of technical standards for the planned month on an average daily basis. Due to the existing restructuring of logistics and uneven transportation, the use of planned technical standards is difficult. Because even a slight increase in freight traffic can lead to an excess or shortage of locomotive fleet on the sites. The use of an objective operational management methodology, as well as its competent implementation, is the beginning of high-quality freight and train work with minimal operating costs. Therefore, it is extremely important to identify possible options for operational planning of traction resources, the implementation of which leads to efficient operation of locomotives, as well as timely installation of traction rolling stock for maintenance, repairs and equipment. The authors' analysis of statistical data over a long period has shown that the existing methodology for calculating operational fleet planning indicators does not take into account individual factors affecting the determination of the actual size of the required locomotive fleet.
   The article considers real examples of the organization of the corporate locomotive fleet within the West Siberian Railway. The location of the loading station in Kuzbass, and therefore the distance travelled by empty and then loaded trains, is not taken into account when planning transportation, as train flows do not always follow the shortest route (depending on the operational situation).
   Attention should also be paid to so - called delayed trains. The most common reasons why trains are delayed at stations of the West Siberian Railway are downtime of trains at intermediate stations for more than 6 hours, non-acceptance of trains by the consignees, as well as the absence of a locomotive carrier. A large accumulation of such trains at stations can lead to difficulties in passing trains and additional work of the locomotive fleet.
   The purpose of the study is to determine the dependence of the volume of the required locomotive fleet on changes in the organization of its use in freight traffic, taking into account additional factors.
   It was found that during the operational planning of train operations in freight traffic using automated programs of the PROGRESS system, based on calculations of locomotive turnover using the analytical method used everywhere, additional time components were not taken into account, taking into account the current operational situation at the landfill. It is proposed to supplement the methodology for determining the turnover of locomotives with elements that take into account the real situation and take into account the additional work of the locomotive fleet.
