The paper presents the method of calculating the wear intensity and durability of rail wheels based on the wear model constructed with the help of dimensional analysis. In this work research of wear intensity of tyre and rail steels has been made. Results of these experiments have been used to calculate service wear intensity of rail wheels. The calculations proved that the material property sufficient to determine the wear intensity of rail wheels is the hardness of wheels and rails. The working conditions of the tribological wheel/rail system is characterised by maximum Hertzian pressure and creep. The dependence of the wear intensity on the longitudinal creep in the tread of the wheel, the track curvature, the wheel and rail hardness have been calculated.
