Given the prospects for the future development of interstate transportation in the Northwest region and the positive experience of operating the St. Petersburg — Helsinki line, the article conducts an analysis of the state automation and remote control systems on the main cross-border railway routes of the Oktyabrskaya Railway. The conducted analysis revealed that there are two most promising cross-border railway sections with direct access to the main railway line and the ports of the Barents and White Seas. From the Finnish side: the section from Alakurtti station to Ruchii Karelskiye station, which can potentially be extended to the nearest Finnish station, Salla (approximately 70–75 km). From the Norwegian side: the section from Nickel-Murmansk station to Kola station, with plans to extend it to the Norwegian station, Kirkenes (approximately 50–60 km). On these sections, there is a need for the modernization automation and remote control systems. Additionally, the article proposes a technical solution for the modernization of these systems, with simultaneous reduction in operational costs for their maintenance. The essence of the solution lies in the utilization of a microprocessor interlocking system with a distributed control architecture, the principles of coordinate train traffic management, and the application of minimally-manned maintenance technologies for automation and remote control systems devices.
