ABSTRACT:
A rail vehicle with spring support of its car body on an underframe with flanged wheels for guidance and support on a track. Permanent magnets are provided on the underframe, which exert an attraction counter to the wheel load on armature bars extending along the track. The magnetic force of the magnets is controllable as a function of the load (weight) of the car body by an increase or decrease of the magnetic resistance of a ferromagnetic magnet core by mechanical means as the load decreases or increases.
