The article is devoted to the analysis of the most used additives for lubricants. The principle of their operation and the result of their work are considered. The effect of additives on the structure of surface layers on the surface of friction pairs is est imated. The analysis showed the use of only a limited number of principles of the action of antifriction additives. Theoretically promising antifriction additives for base oils, relevant for use in railway transport, have been proposed.

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.
