The track (8, 11, 12) has lateral rails (9, 10) to guide the vehicle. One segment of the track (1) has an outer contour which forms a loop and the lateral external rail (3) extends along this contour. This rail has an entry segment (4) joined to the rail (9) of the track. An exit segment (5) is at an obtuse angle (A), of about 120 deg., to the entry segment and is joined to the other rail (10) of the track. The segment has an inner curved rail (6) which is mainly parallel to the outer curved rail.
