Increasing train speeds on existing railways and the future development of high-speed rail links with speeds of up to 400 km/h place increased demands on all components of rail transport. The aerodynamic impact of high-speed trains on infrastructure deserves special attention. In connection with the fact that the maximum speed of rolling stock circulation on the network of operating railways reaches 250 km/h in a very small section of the St. Petersburg-Moscow line. The goal of experimental simulation of aerodynamic impact of a moving train on infrastructure objects in wind tunnels can be classified as unrealizable, then, to calculate this impact the use of software packages is required. This paper presents the development and verification of a computational aerodynamic model of high-speed train impact on infrastructure objects. The model is verified by the results of domestic and foreign studies and the conclusion is made about the possibility of its further application.
