In the calculation of structures located near railway tracks (noise protection screens along the tracks, overpasses over high-speed railway lines (HSM) of deck elements with downhill driving, etc.), the aerodynamic effects of high-speed trains shall be considered. Objective: study of the aerodynamic impact of a moving high-speed train on structures and structures, Located in the immediate vicinity of the highspeed railway line with subsequent adjustment of the current regulatory framework for the design of TSM infrastructure facilities. Methods: mathematical modeling in a specialized software complex of computational hydrogas dynamics with experimental verification of the developed calculation models and subsequent analysis and generalization of the obtained results. Results: distribution patterns and aerodynamic intensities from a moving high-speed train for the two most characteristic design cases: impact on a vertical surface parallel to the track axis and on a horizontal surface, located above the axis of train movement. For the calculation cases under consideration, the intensity of the impact was related to parameters such as the distance to the structure from the path axis (for the vertical surface) and the height above the rail head (for the horizontal surface). Practical importance: the need Development of proposals for adjustment and addition of the current regulatory framework for the design of structures and structures included in the infrastructure of high-speed railway lines.
