Abstract. In order to determine the method of contact surface treatment and to define the rational surface roughness in the wheel/rail contact for the minimal growth rate of contact fatigue defects the program of experiments in operational conditions was developed. On the basis of the results and calculations the coefficients of regression equations, which describe dependencies of the wear rate on the parameters of the contact surface treatment in real operational conditions were obtained. Besides, the diagrams of dependencies of the friction coefficient on the roughness of railhead contact surface of the high rails with and without lubrication, when laid in curves of underground systems, were built. The experiments conducted in operational conditions of Kharkiv Metro revealed the influence of roughness of the railhead side surface of the high rails in curves on the contact fatigue defect development after preventive grinding and lubrication. According to the results of the experiments it was established that the rail preventive grinding with simultaneous lubrication led to slower contact fatigue defect development in rails of underground systems. The rational roughness of the railhead side surface of the high rails in curves after preventive grinding, which led to the minimal rate of defect development, was defined.

“…Basically, among the possible ways to achieve this, the change of the contact parameters was considered. In particular, it was noted that, despite the high cost of replacing worn-out wheels and rails, and the labor content of repair work, the solution of these problems is a priority [2][3][4]. For now, the problem of reducing the wear rate for the contact «wheel-rail» taking into account all features of contacting wasn't resolved.…”

“…A number of test approaches exist for assessing wheel and rail material performance as shown in Table 1 and Figure 7. The most commonly used approaches are small-scale pin-on-disc tribometers [34][35][36][37] and twin-disc machines [12,[38][39][40][41], largely due to their availability and because tests are relatively quick and cheap to carry out. Scaled test-rigs exist [42] and full-scale experiments are possible [25,[43][44][45][46].…”

The wheel-rail contact is an open system contact, which is subjected to various environmental conditions, such as temperature, humidity, water, and even leaves. All these environmental factors influence wheel-rail wear. Classical wheel-rail wear has been extensively studied under dry and clean conditions previously. However, with changes in environmental conditions, the wear rate and wear mechanism can change. This paper reviews recent contributions to wheel-rail wear with a special focus on the influence of environmental conditions. The main part includes the basics of wheel-rail wear, experimental methodology, wear and rolling contact fatigue (RCF), and some measures to counter these degradation mechanisms.
