Determination of the Simulation Method of Technical Equipment and Technological Support for Non-public Tracks

Abstract

AbstractThis article considers the issues of determining the technical equipment and technological support of non-public tracks, using the example of the station “M”. The analysis of the technical and operational characteristics of the station and the planned freight traffic was made. The characteristic of technical means and devices providing the basic technological operations of the station “M” is presented. Substantiation of development of railway infrastructure of stations with the use of simulation modeling method has been proposed enabling to take into account rather detailed technology of station operation and to investigate the functioning process of station transport service system by varying the main characteristic of devices - number of tracks, loading facilities of the station and shunting locomotives. As a result of processing empirical data using the application program package Statistics (Statistica), theoretical probability distribution curves for the occupancy duration of the station shunting area track, its sample mean, standard deviation and coefficient of variation were obtained. The irregularity coefficient of freight operation at station “M” was determined to use it in the model, the loading of all major devices of the station in question was calculated and delays in waiting for service were determined. In the course of various experiments with the model of transport system functioning, the necessary for mastering the prospective work volumes were determined: track development and the number of shunting locomotives. Determination of the necessary development of the railway infrastructure of other non-public tracks can be carried out in the proposed order.KeywordsRailway trackTrack developmentRailway stationSimulation modelingReconstruction
