Abstract: This invention relates to a method on a truck for railway vehicles to measure the curvature of a track and a method for configuring the steering orientation of an axle of a rail truck as a function of the curvature of the track, which axle is rotationally fastened to a truck frame. The curvature of the track is determined by dividing a yaw rate by a translation rate, and the wheels are oriented on the basis of a setpoint steering angle (&ggr;setpoint) which is calculated by multiplying the track curvature (&khgr;) by one-half the distance between the two axles of the truck.

Abstract: A rail vehicle with at least one driving unit and at least one adjacent wagon body that is capable of tilting during operation, where the tilting is provided by an assembly mounted on a travelling gear. The driving unit and the adjacent wagon body have their facing ends supported on a common travelling gear having at least two sets of wheels.
