The results of studies on the possibility of application of ozonized air to reduce the wear and tear in the tribocontact "wheel-rail" are presented. The technique of influence estimation of ozonized air, as activator surface, on the friction interaction in wheel-rail contact, is proposed, the results of experimental research results are presented.

This paper describes a wheel - rail contact for a case when one contact point is located on the wheel tread while the other is on the wheel flange. The locations of these points are determined for both wheels for given lateral displacement and yaw angle of a wheelset. Numerical simulation results are presented for new and worn rail-wheel profiles in order to demonstrate a developed algorithm.
