  • the provided during operation wheels have transversely to the direction of a predetermined width, which utilizes at least half the width of the treads 42, 42 a.
  • the subdivision of the region of the rail joint into sections can here be arbitrarily refined, without resulting in sections with missing support area.
  • the mandrels 79 are arranged at the transversely to the rail direction outer ends of the treads 42, 42 a and directly below these treads 42, 42 a.
  • the rail system 1 has two further running surfaces 43, 43a, which are formed in the lower region of the rails 71 and are inclined against each other and against the running surfaces 42, 42a such that the middle planes of four each on a running surface 42, 42a, 43, 43a rolling wheels form an X-arrangement.
  • treads 42, 42a are intended for the wheels carrying the weight, support wheels engage the treads 43, 43a, which guide the vehicle and hold it on the rail 71.
  • three wheels are provided, whose center planes form a Y-arrangement or a reverse Y-arrangement, and the running surfaces are formed accordingly.
  • two counter-rotating wheels positioned above the rail carry the weight of the vehicle while the third wheel is located below the rail and hold the vehicle on the rail.
  • the reverse Y arrangement results from reversing the described Y arrangement in which the single, third wheel is disposed vertically above the rail and supports the weight of the vehicle. Further arrangements are realized in further embodiments.
  • the rail joints are bridged by a connecting element, wherein the rail ends are aligned with each other and are displaceable in the rail direction.
  • the rails and the connecting element are designed such that there is no interruption in running surfaces on the rail joint.
