The East Siberian railway runs through the territory of 4 subjects of the country in which there are difficult climatic conditions. This railway carries the TRANS-Siberian and Baikal-Amur mainlines. The length of the operational road of Federal significance exceeds 3,800 km, which is 4.5 % of the entire railway network. At the same time, having a complex terrain of the track with various degrees of curves, the load increases every year on the entire network of the East Siberian railway. To increase cargo turnover, long-distance trains are made up, which, according to statistics, are most often subjected to a descent in conjunction with a violation of the speed limit.

Due to the high level of capacity on the East Siberian railway and the difficulty of ensuring uninterrupted passage of existing train flows with large volumes of work on track sanitization, it is advisable for freight trains to provide a longitudinal force. The longitudinal strength obtained by calculations and for one of the junctions on the track section of the East Siberian railway revealed an excess of the maximum permissible values. An analytical description of the experimental data is proposed by the proposed expression, which meets the requirements for the reliability of the result, which is important when considering the norms of longitudinal effort. The critical speed of an empty car is determined. The article presents the dependence of the speed of the rolling stock on the amount of longitudinal forces acting on nearby cars in the composition.
