Constructive decisions for upgrading the crew of high-speed electric trains that exert a high level of force on the track in curved sections are described. The decisions provide for the replacement of cassette bearings with radial spherical double-row roller bearings, the installation of new axle boxes with a lock on a spherical hinge, and the replacement of the standard silent block with a combined one with clearances, which ensures the radial installation of wheelsets in curves. The simulation results confirming the effectiveness of the proposed solutions are presented. It is found out that the latter option is the most rational and can be implemented in repair depots. It reduces lateral forces in curves and wheel wear. To dampen vibrations, it is advisable to use friction dampers, which, in combination with hydraulic dampers, ensure smooth running even at high speeds.
