Abstract: In magnetic levitation vehicles, supporting and driving forces are generated by a long stator on the track and permanent magnets on the vehicle. The underside of a rail provides the attachment of the long stator; the rail further has two oppositely disposed horizontal running surfaces for pairs of spacer rollers on the vehicle and a vertical running surface for lateral guide rollers on the vehicle. For a particularly simple and inexpensive production of the rail it is proposed to make the one end section of the railhead of the rail the horizontal running surfaces and a lateral guide profile fastened to the underside of the railhead the vertical running surface.
