Abstract: Wheels of rail vehicles are trued while the wheels are kept rotating about a wheel center of rotation that is continuously corrected to keep the center of rotation in a fixed position in response to eccentricities a wheel may have, especially in its outer circumference. For this purpose, a sensor for each wheel of two wheels forming a set senses a respective excursion of a center of rotation of each wheel being trued in a set to provide respective excursion signals which are supplied to a central processing unit that provides control signals to a power drive for wheel guide rollers which support the wheel set to be trued. The power drive applies wheel position adjusting force components, preferably directed radially relative to the respective wheel rotational axis in response to the control signals from the central processing unit whereby the excursions are compensated and the wheel rotation center is kept in a fixed position.
