The results of a theoretical study of the vertical impact of multiaxial locomotives on the track based on the wave theory of elastic deformation propagation are presented. Theoretical and practical problems of dynamic characteristics research at the design stage of modernization of new and existing rail vehicles. Consideration of the impact of compliance with standards on the impact on railway tracks. These issues in the context of crews can be successfully solved using modern methods of analysis and synthesis of dynamic systems. Calculations and practical experiments using modern computer and recording equipment are widely used for dynamic systems. Keywords. Carriage-path, vertical impact of multi-axle locomotives on the track, speed increase, models for analyzing indicators of dynamic qualities of locomotives during vertical fluctuations.
