Lateral guidance apparatus for laterally guiding a wheel set of a rail vehicle with respect to a support rail. The apparatus includes electromagnets carried with the wheel sets and positioned and controlled so as to effect return of the wheel set to a central position along the rail whenever the wheel set deviates from such central position. In a first preferred embodiment, the electromagnets are positioned at respective opposite sides of the rail supporting the vehicle wheels, with means for controlling the current in the electromagnets so that the magnetic force set up between the poles of the magnets and the support rail effects an automatic return of the wheel set to a desired central operating position. Some preferred embodiments include active control systems which vary the supply of electric current to the electromagnets as a function of the detected deviation of the wheel set from the central position on the rail, while other systems use passive control with constant supply of current to the electromagnets. In a preferred embodiment, the electromagnets, including the poles, are disposed above the support surface of the rail so as not to interfere with rail switching systems and the like.
