“…In connection with displacement of the cut stop point, it can be assumed that the track occupancy level will be below the permissible value. The track occupancy level can be presented with the following formula [30]: Table 1 shows results of the experiment. The following conclusions can be made on the basis of Table 1 and Figure 3: …”

“…This means that the standard profile accumulates on an average 36 cars more before the first backing-out.  [30] indicates that the track occupancy level must be within 0.8 to 1 according to the regulatory documents. This condition is satisfied in most cases for the standard profile, both during humping at the free track and in the course of accumulation of cars on the track, on which cars are already located.…”

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.

“…In this context, the European Union would be interested in the experience of the Russian Federation, which has long been one of the leaders in the development of rail transport. The concept of reducing shunting time has been implemented in our country since the 2000s and a large number of articles have been devoted to it [12][13][14][15][16][17][18][19][20][21][22].…”

Developing rail transport is one of the world's greatest challenges. Rail transport reduces emissions and is the most energy efficient means of transport. An important element of the railways is a hump yard, where rolling stock is formed. The purpose of this article is to describe the mathematical apparatus for calculating the speed of a multiple unit train at a marshalling yard. As a calculation method, the articulated-axis model is used. In this model, the trailer is not seen as a material point, but as several physical bodies. Due to this model, it is possible to simulate multi-carriages moving along heterogeneous profile. It was found that for multi-car trailers the spread of the main co-protection will be lower than for single-car trailers. In addition, as a result of accounting for multi-car trains, the profile requirements are reduced when calculating marshalling yards. The results obtained can be used to design hump yards and automate existing hump yards.
