The paper focuses on topical issues relating to the maintenance of buffer spans and temporarily repaired sections of continuous welded rail (CWR) tracks. The paper is aimed at developing and studying the feasibility of a technology for replacing temperature-stressed continuous welded rails. For the purposes of this research, the analytical modeling method is used. A design model for moving the end of the stressed rail to the side is presented. Equations of deflections and bending moments arising when the rail is bent to the rated value were derived. Stresses on the rail bending length were determined and compared with the maximum allowable ones. A resource-saving technology has been developed for replacing temperature-stressed buffer rails of a CWR track using intermediate rail fastening Vossloh W-30.
