The movement of a freight train along the unevenness of the railway was investigated with the presence of various retreats by deviations and standardized degrees in stationary modes. An expression is proposed for calculating the component of the main resistance to movement, which depends on the spatial vibrations of the cars. In the MATLAB Simulink system the movement of a freight train was simulated, consisting of 56 gondola cars of 12–132 model in a fully loaded state on bogies of 18–100 model in a new and worn condition. The resistance dependences to oscillatory motion of such cars on the speed of the train are obtained. It is noted that the main contribution to the resistance to the oscillatory movement of the cars in the train is due to the creep forces. The most intense “surge” of the main resistance to the movement of the train is observed for wagons with worn-out bogies on the way with the presence of deviations of III-IV degrees at a speed of 70 km/h. The obtained dependencies will allow to study the movement of a freight train with a locomotive at the head over uneven railways tracks under the action of tangential forces of traction motors of a locomotive of limited power in dynamic modes for various types of locomotives and modes of train driving.
