The processing ability of the sorting hill depends on the sorting park, where the accumulation of wagons takes place. Changing the longitudinal profile of the sorting fleet path leads to an deposition and uncoupling of wagons due to commercial malfunctions, which increases the hill interval. One of the methods for calculating the impact of changes in the longitudinal profile of the track on the quality of the sorting system is simulation. Despite the high accuracy of this method, its implementation is quite complicated. The possibility of using the concavity coefficient of the longitudinal profile of the sorting park path to analyze the quality of its filling is considered. The developed simulation model of filling the paths of the sorting park “SortPark 2” was applied, taking into account the moving of the trailer from the place after the stop; the error in the operation of control devices and setting the release speed of the couplers from the park brake position to the path; the movement of cars in the collision with them of the next release. Studies have shown that the concavity coefficient can be used as a numerical criterion in assessing the deviation of the profile from standard values. There is a relationship between the concavity coefficient and the path fill quality index. The results can be used to assess the effectiveness of straightening the profile of the path.
