The classification of rolling surface defects of wheelsets of high-speed electric trains was given. It was revealed that in practice there were more than 60 types of defects of solid-rolled wheelsets that arise under the influence of various factors that directly or indirectly affect traffic safety. The reasons affecting the wear of the rolling surface of wheelsets of high-speed electric trains were considered. Positions of authors dealing with issues of studying the processes of friction and wear expressing different opinions about the nature of the wear of the wheel-rail set friction were presented. We developed a research methodology allowing to identify the degree of impact of proposed methods on the durability of the rolling surface of wheelsets based on a model of multidimensional analysis of the choice of the most effective methods, as well as to identify the needs of a specific locomotive depot when applying each of the methods. We proposed a method to increase the resource of wheelsets by changing the design of the rail joint. Since the disadvantage of the existing butt device was the dynamic effect of the wheel on the upper edge of the rail head. the article presented a variant of using rails with a bevel of joints at an angle of 45 degrees on railways. Their use would increase the durability of the rail track and, as a result, the durability of the wheel-rail set friction.
