Purpose: To determine the most promising materials for creating the HSR car bodies. To select the optimal welding methods for their assembly. Methods: An analysis of the properties of current and prospective metals used in the manufacture of high-speed railway car bodies by leading rolling stock manufacturers in Europe, Japan and China. Results: In the fabrication of HST car bodies, the most prevalent structures are composed of stainless steel and aluminum alloys, which are joined by various welding methods. At present, laser welding has been found the most technologically advanced method, due to its high degree of automation and the high quality of the resulting welded joints. Practical significance: The recommendations stated in the paper are intended for designers and railway car body builders to create and build the first Russian high-speed train, the “White Gyrfalcon”.
