ABSTRACT:
The lifting step of the entry stair for rail vehicles is guided on both sides by two parallel guide brackets and while staying parallel to an extendable and retractable vehicle floor, forms a shallow arc from one end position to the other. In its upper end position it is level with the vehicle floor. The vehicle door closes along its outer edge with an elastic door seal. The folding step turns around the turning axis. In the "up" position the folding step stands about vertically and, together with the covering plate attached to the lifting step, forms a flush covering apron completing the side wall of the vehicle. The angle of incline for the stairs, in general, might be about 40.degree.. This stair system does not form any niches when in the "under way" position wherein ice and snow could accumulate. Nor does this stairway require additional covering parts such as movable covering aprons, etc.
