The rail track is in continuous contact with a locomotive pair of wheels. It is elastic coupling to its traction drive and as such affects the dynamic processes occurring in it. This impact is estimated using the parameters, characterizing the stress-related properties of a rail track longitudinally and called its longitudinal stiffness. The subject of the study is small oscillations of the system” rail track – locomotive traction drive”. In this case, the traction drive can be considered autonomous in relation to the locomotive and be selected from the general system. In this study, we carried out a study of small free and forced oscillations of traction drive with the influence of the rail track. This impact is significant. It was found out that the free oscillation frequency of the system “tractive drive – railway line” depends on technical condition of a railway line and on some of its sections the resonance is possible which consequence is slipping of the locomotive wheels on rails sometimes changing into the wheel spinning.
