In construction of high-speed continuous welded railway lines the high-strength rails, welded by different methods, have a mass application. With the appearance of high-strength rails with a high carbon content, the necessity of implementation of heat treatment operation of butt welded joints in a cycle of rail section manufacture became urgent. The aim of the presented review is the analysis of problems and forecasting the prospects of nowadays technologies of heat treatment of high-strength rail butt welded joints. Different methods of heat treatment used in industry were considered. Different schemes of heating and cooling of rail weld and their effect on formation of microstructure and mechanical properties of joint metal were analyzed. A review of references showed that the technology of high-frequency current heating with further hardening of a head is the most requested during heat treatment of butt welded joints of high-strength rails. 31 Ref., 6 Figures.
