Stability issues of the continuous welded rail track on the concrete sleepers on the curves with radius R≤300 m

摘要

This paper describes the economic and technological benefits of installing continuous welded rail (CWR) track on sharp (radius≤300 m) railway curves. A new form of prestressed concrete sleepers developed by the V. Lazaryan Dniprope-trovsk National University of Railway Transport is shown to improve the lateral shift resistance of CWR track in sharp curves and the use of anchor sleepers on tangents is shown to make it possible to lower the fastening temperature of the CWR track in order to increase the rail lifespan.
