The article deals with the problem of wear of the train wheel crest and the conditions that affect the process of deformation of the material of the wheelset parts. Factors affecting wear are considered. It is shown that the resource of ridges depends on the nature and speed of chemical and physical processes. It was noted that in the center of destruction of the ridge, an increased content of carbon, oxygen and silicon was detected. It is established that the main way to reduce wear is to lubricate the comb in order to reduce the coefficient of friction.
