“…Hump yards are one of the most important elements of the transport network, therefore, upgrading of the humps is viewed as one of the main goals of transport development in Russia [1] and in Western Europe [2][3][4][5]. This is due to the fact that most of the time required for delivery of goods falls on shunting operations performed at hump yards [6][7][8]. To reduce this time, it is necessary to increase the hump yard capacity.…”

To increase the hump yard capacity, it is necessary to ensure high quality of sorting track occupancy. The purpose of this paper is to study the effect of changing the track profile on the quality of its occupancy. The simulation model developed for occupancy of sorting tracks based on the calculation of the speed of the cut and taking the following into consideration was used for the study: the possibility of starting the cut movement after a stop, errors in operation of the devices in charge of the speed of releasing the cut to the track, the possibility of displacement of the cars when the next cut collides with them. A real profile of the sorting facility track was analyzed as an example of it. It was determined that the profile caused strong effect on the track occupancy quality. The sagging of the profile causes an increase in the probability of collision of the cuts with exceeding the permissible speed. An increase in the up-gradient reduces the range of the run-off distance, which in turn causes an increase in the number of car back-ins. Profile correction will allow increasing the track occupancy quality.
