Development of a flow diagram for the calculation of rolling stock anchoring rates algorithm taking into account the station track profile

Abstract

One of the factors to ensure the trouble-free operation of JSC Russian Railways in compliance with applicable standards, rules and instructions is the introduction of unmanned technologies and the development of measures aimed at minimizing human labor. The complex structure of the railway system does not allow an employee to be completely removed from organizational and technological activities, since it requires the continuous making of the most important management decisions at all stages of the transportation process. Based on the above, the successful functioning of the Russian Railways company is impossible without qualified personnel, one of the ways to improve its productivity being continuous production training. Transport accidents and events resulting from the violation of traffic safety rules and the operation of railway transport emphasize the relevance of studying the issues of securing rolling stock on the station tracks in order to prevent its spontaneous movement. The task set within the framework of the article was not relevant when the fleet of wagons was equipped with axle boxes with plain bearings, which had significant resistance to starting. The transition from plain  to roller bearings has raised the urgency of the issue of ensuring safety when securing rolling stock. The list of initial data necessary for calculating the norms for manual fixing of wagons implies the supplementation of existing formulas with correction factors. Each formula has a broad justification for the possibilities of its use. Currently, various technical means are being developed, whose main purpose is to minimize human labor and eliminate errors in calculating the number and location of brake shoes. However, alternative methods of mechanized fastening require precise setting of the train in front of the stop. It is obvious that the use of a specific method of securing is due to the throughput and processing capacity of the station in question, and the rationale for changing one to another will be determined by a feasibility study, including an assessment of the reduction in the amount of the rolling stock forced downtime on the station tracks. The presented block diagram of the algorithm for calculating the norms of fixing can be used in the educational process.
