Application of ballastless construction of the railroad track in the Arctic zone
Abstract: the article provides a calculation justification of the proposed railway structure on a reinforced concrete sleeper-free base, for which an analysis of the existing methodology for calculating the railway track for strength is carried out, according to which for a railway track on a sleepe...
