The axles (6) or half-axles (8) of the car body (1) are steered by linear actuators (7) according to the known radius of the track, stored in a computer memory as a function of the longwise coordinate of the track. The two wheels (3) of an axle can rotate independently, solution preferred for all the wheels, except those of the leading axle, or can rotate in agreement. In this last alternative, preferred for the leading axle, a given difference in rotational speed is imparted to the two wheels according to the curvature of the track. The patent describes a closed differential that is suitable to impose that precise difference in rotational speed to the two wheels of an axle. The invention includes the case in which the wheels are steered by the movement of an Ackermann articulation (9) .The device allows higher train speeds with equal dynamic stability. A high-speed service can thus be operated on conventional tracks, without the radii of curvature and the corresponding dimensional tolerances.
