STUDY OF CONDITIONS FOR DRIVING CONNECTED TRAINS ON THE FIRST RANGE

At present, Russian Railways is operating under conditions of intensive growth in freight traffic to ports, border crossings, and large industrial enterprises in the Far East. This is due to a number of external economic factors and market specifics. The raw-material nature of the Russian economy and the consequences of the global crisis forced industrialists to start looking for new sales markets, the way to which runs along the East-West international transport corridor and is provided by the railway and Pacific ports. Over the past five years, the industry has not seen the large-scale investments that it so much needs to develop the Russian railway network. Of the global events, only the renewal of the freight car fleet and the construction of infrastructure for non-public tracks took place. The lack of investment has led to an increase in the network’s capacity and capacity deficit and, as a result, to an unmet demand for transportation. The dynamic growth of traffic volumes has always been matched by the development of the railway network. Increasing the weight norms of freight trains is one of the priority directions, allowing to increase the reserve carrying capacity and carrying capacity, as well as to improve the efficiency of railways in market conditions. Purpose. At the DVZhd landfill, there is a lack of capacity in all directions to the ports. In order to accelerate the movement of train traffic to them, it becomes necessary to consider all possible options. The article discusses issues related to the possibility of passing connected trains on double-track sections of the Far Eastern Railway, both with their constant driving and under conditions of summer track work. Methodology. To solve the problem of the movement of connected trains, graphic and analytical methods of mathematical modeling, scientific methods of collecting and processing statistical data, modern achievements in terms of general principles and methods of risk management are used. Results. The necessary conditions for ensuring the movement of connected trains have been identified. Practical implications consists in comparing the number of connected trains of its formation for the section and transit ones that come from the Transbaikal railway and the Arkhara - Khabarovsk II section, identifying the preferred directions of such trains, as well as positive and negative impacts on such indicators as the average train weight and section speed.
