Purpose: To increase economic efficiency of the process of finding and moving loaded and empty cars on the basis of improving the dynamic model of loading the infrastructure of JSC “Russian Railways” during the implementation of the process of approving applications for cargo transportation and notification requests for the transportation of empty wagons. Methods: Systematic approach and the theory of algorithms have been used to find out the reasons for the accumulation of cars on railways, an analysis has been made of the current distribution of car traffic in the North-Western Polygon to identify systemic patterns that encourage an increase in economic costs. Results: A method of stage-by-stage progress of car traffic has been developed, which allows to synchronize the capabilities and needs of participants of the transport services market in order to obtain a positive economic effect; the conditions for the uniform loading of infrastructure elements are determined, which make it possible to exclude overloading of critically important sections. Practical significance: The method allows us to balance the capacity of the infrastructure and the processing capacity of the consignee, which increases the economic efficiency of the transportation process. Consignees will have access to a tool that allows them to influence the progress of goods to their address, and the carrier will reduce operating costs by eliminating the occupation of infrastructure at the approaches to destination stations.
