Abstract: On one ground rail only, a vehicle containing upper and lower bogies is rolling. The vehicle is guided from above at a ceiling rail. Each lower bogie contains a bogie wheel which is provided with lateral flanges. The ground rail includes a head profile, the upper side of which is interrupted at branch points of the rail by slots to guide the flanges of the bogie wheel. The depth of the slots is substantially less than the height of the head profile. Guide rollers, which can be lifted individually under control to determine the travel direction at the branch points, laterally engage the head profile.
