Study of the method of placing technical stations

Abstract

At present, the organization of transportation by rail is associated with the processing of trains and wagons along the route. Accommodation and equipping of technical stations play a major role in the organization of the transportation process. The uninterrupted operation of the technical stations ensures the stability of the railway transport as a whole. The distance between the technical stations determines the duration of operation of the locomotive crew, the efficient use of the locomotive, the required number of locomotive crews and locomotives for carrying out the transportation plan, and also improves the main indicators of the railway. However, often train locomotives do not fulfill their assigned tasks due to the lack of time for the locomotive crew in order to deliver the train to the nearest technical station, as well as the irrational use of the standard time of the locomotive crew. In connection with the expectation of delivery, the locomotive brigade replacing the locomotive, the idle time of the wagons at the intermediate stations increases. All this makes it difficult to control the movement of trains and reduces the speed of moving cars on the railway transport. The purpose of the study is to develop a method for placing technical stations on a railway test site in the course of an electric traction. To achieve this goal, it will be necessary to solve the following tasks: generalization of the main parameters of the location of technical stations; determination of half-races between technical stations in the operation of one locomotive brigade; search for the required number of change of the locomotive brigade; determination of the distance between technical stations. The methods of research are based on the generalization and analysis of existing results in finding the rational location of technical stations. Results: It is revealed that the first step for the rational placement of technical stations is to determine the traction arm of the locomotive. When determining the length of the traction arm, the ways of using the locomotive for the duration of working time by one locomotive crew are considered. Practical significance: The rational placement of technical stations according to the proposed methodology will ensure the advancement of trains with the least number of parking lots for the replacement of locomotives, locomotive crews and inspection of rolling stock.
