ABSTRACT:
A plurality of stairs are interconnected and propelled in a racetrack pattern between two floors of a building. The stairs are guided on rails and provide moving staircase sections for passengers to stand on for transport between the floors. The stairs move flatly in line with each other beneath the floor level in going from one of these staircase sections to the other. The stairs are interconnected and mounted on the rails in such a way that they can rotate relative to each other so that they can turn in going from one staircase section to the other.
