Influence of the organization of the movementof the united freight trains on the increasingof the capacity of the plots electrified on a dc

The analysis of the influence of the organization of the formation of United freight trains on the throughput capacity of railway sections has been carried out. The results of electrical calculations of the 3.0 kV dc power supply system of 3 sections of the Sverdlovsk and South Ural railways are presented when controlling the speed of trains from 50 km / h to 100 km / h with various locomotives while passing two single and one connected cargo trains using the system of contactless automatic voltage regulation in the contact network, allowing to assess the throughput capacity of the three sections. In the course of the calculations, the developed refinement method was applied using the correction current factors KIxx and KIst. Proved the need for their use in electrical calculations.
