Abstract:
A platform door system (1) comprising a barrier (10), which includes screen or barrier elements (12) able to be aligned along a track (3) and/or a platform (4), the barrier elements (12) being able to be shifted on two mutually spaced rails (16 and 16â€²) in relation to one another in such a manner that they can at least partially overlap with each other so that freely definable, predetermined openings (5) may be created along the track (3) and/or platform (4), the barrier elements (12) being able to be shifted along the rails (16 and 16â€²) in both directions such that should the train fail to stop in the intended position, the barrier can be shifted a distance equal to the amount by which the train has missed its intended position, characterized in that the barrier elements (12) each have locking devices (14) and sealing devices (15), the locking devices (14) serving to releasably lock the barrier elements (12) in the rails (16 and 16â€²) and the sealing devices (15) serving to produce a seal between adjacent barrier elements (12).
