The article presents model studies of the dynamics of the transport system for the structure of the rail vehicle of the underground railway. In this case, the subject of the research is the system of rail vehicle – track – tunnel – subsoil. Dynamic interactions were investigated be-tween the tunnel and the subsoil modeled with elastic half-space. Tunnel transmittances have been determined for the conditions of the first Warsaw subway line. The usefulness of the proposed modeling method in the study of the influence of modern means of transport on urban infrastructure has been demonstrated.
