The invention relates to a dual track system for rail vehicles and magnetic vehicles. To enable this track system to be used in common by conventional wheel-and-track vehicles and magnetic vehicles, switches are needed by which both types of vehicle can be switched from a track on which only the one type of vehicle can run to a track which can be used by both types of vehicle. Furthermore, the switch must be suited for providing branches in a track on which both types of vehicles can operate. For the solution of this problem the invention provides a switch system which is essentially characterized by a flexible beam (6a) on which a likewise flexible track section (21) is mounted, which is intended for common use by rail vehicles and magnetic vehicles, and by an apparatus (31) for opening or closing a gap (30) between the beam and each such track (1a) to be traversed by the rail vehicles which permits the flexing of the beam.
