Dependence of the service speed on the provision of transit trains with locomotives on the Koshta — Babayevo railway section
Introduction. Today, ensuring stable train traffic remains relevant, particularly on the heavy traffic lines of the Russian Railways network. Solutions to this problem largely involve the development of polygon technologies based on harmonised use of the infrastructure, locomotive and car fleets. Th...
