FIELD: railway transport. SUBSTANCE: two-axle vehicle bogies provide self-alignment of wheelsets when negotiating curvilinear section of rail track. Bogie has vertical wheelset turning axles with independently rotating wheels, and coupling members. When entering curved track section, front wheelset, in direction of running, gets turned under the action of force from outer rail, around vertical axle towards inner rail and turns synchronously rear wheelset around vertical axle towards inner rail. EFFECT: enhanced operation reliability of bogie owing to reduced efforts of engagement of wheels and rails. 1 dwg
