This paper presents an insight into mathematical analysis of dynamic models of the vehicle–track system. After identification of its advantages and disadvantages, an improved three-dimensional "vehicle–track" system of a mathematical model is presented. It not only assesses the influence of realistic track irregularities but also on all elements of the railway structure: rail, rail pads, sleepers, ballasts, and subballast parameters on the wagon’s movement smoothness. Based on the expanded mathematical model of the “vehicle–track” dynamic system, the dynamic process of the wagon was theoretically studied, and the effect of track with irregularities on the vibrations of the wagon elements was studied. The final conclusions and recommendations are presented.
