Efficiency justification of the double-tread profile wheelset passage along specific track section

Abstract

Rolling stock operated in the urban railways environment is a significant, efficient and environmentally friendly mass transit system that forms an indispensable part of modern cities. In this system, the problem of tramcars passing small radius arches appears to be topical. In many European cities, on tracks with a gauge of 1000 mm, where curves with a radius of 50 m are common, under arduous conditions, arches of the track with a radius of 18 m and more are built, with a requirement for the vehicle design to be able to pass a track with a curve of 17 m.
