Objective: The solutions to the problem of low-trafc railway lines functioning has been considered, and the approach to improving the efciency of the transport system with the interaction of heavy- and low-trafc lines has been characterized. The transport network management principles have been developed and the mathematical formulation of the problem of increasing the low-trafc lines efciency has been carried out. The authors have supplemented the classication of existing low-trafc lines in order to develop more accurate scenarios for increasing protability and promoting development of low-trafc lines. The article provides a graphic model of heavy- and low-trafc lines management, a control system comprising structural divisions of JSC Russian Railways and regional authorities, taking into account external factors, the demands of the population and enterprises in transportation and their satisfaction, and technical, technological and information resources. Methods: Methods of analysis and synthesis, systems theory, and mathematical modeling have been used. Results: The conceptual structure of the management model for heavy- and low-trafc lines is proposed. Practical importance: A set of indicators for assessing the low-trafc lines performance characteristics is provided, including quantitative technical, technological and economic parameters, as well as indicators for assessing the quality of transport services. The railway line life cycle stages have been determined and the development and operation scenarios for the low-trafc lines have been given.
