In this paper, the influence of high-frequency vibrations in the wheel-rail system is studied, the main causes of their occurrence are described, the study of the structure of M76 rail steel at operating stress levels of 700 MPa and more is given. Investigated the microstructures of samples cut from the actual rails, following the action of high-frequency loading by means of optical microscopy and micro hardness testers.
