The most important component of the Russian transport and logistics complex is rail transport, which is essential for the normal functioning and development of the Russian economy. In the context of Western sanctions, the need to develop railway infrastructure and train traffic management systems is particularly important, as the sovereignty of the state depends on the stability of railway networks. The study identifies the challenges and prospects for the development of the transport and logistics complex in the Russian Federation in the coming years, and highlights the importance of increasing the carrying capacity of the Eastern railway network in the new geopolitical and economic conditions through organizational measures (improving traffic management). The objective of this research is to develop a method for automating dispatching control, which will improve the technology for passing trains on heavily loaded sections. The research methodology is based on statistical data analysis, approaches to mathematical and simulation modeling in railway transport, and the theory of automatic control as a tool for implementing the proposed method and its implementation of the research results on the network of Russian Railways. The results of the study include the consideration of key problems and factors that hinder the implementation of measures to increase the carrying capacity and throughput of railway sections; experiments that resulted in the proposed method of train dispatching during heavy freight traffic. Based on the results of the simulation, the application of the proposed method is demonstrated, and conclusions are drawn about the feasibility of its implementation on the Russian Railways network, which confirm the scientific value of the research results and their relevance for practical application.
