This research paper presents an investigation into the modeling of interaction between railway and train. Using the linear-elastic approximation, the ballast path along which the train passes is considered. The methods of solving the normal and tangential problems, estimating the contact spot for describing the wheel-rail system are given. The numerical simulation of the motion of the rolling stock for different computational meshes is performed by the grid-characteristic method and the fields of the stress tensor components are obtained. When conducting the comparative analysis of the simulation results, it is found that in order to correctly describe the movement of rolling stock the problem commensurate with the length of several wagons, it is necessary to correctly calculate the load in the wheel-rail system, at the same time, the assessment of the contact spot may be less accurate.
