Abstract: A device for the essentially complete bridging of the gap between the car floor of a rail vehicle in the door area and the platform with a gap bridging plate for bridging the gap. The gap bridging plate is mounted to be movable in a linear, horizontal direction at least between a retracted position in which the gap is not bridged and the gap bridging plate essentially does not or only barely projects beyond the front edge of the platform or of the rail vehicle, and an extended position in which the gap is essentially completely bridged. The device is characterized in that the gap bridging plate is mounted movably on two guide rails, and the guide rails are designed as ball bearing linear guides or as roller linear guides.

Abstract: The invention relates to a particularly reliable sliding door construction for platforms, by means of which a passenger area of platforms may be separated from a track area when closed, preventing entry to an arriving train and permitting access to the arriving train in an open state, comprising stationary regions and sliding doors, both the stationary regions and the sliding doors having a height of 1-2 m above the floor level of the passenger region above which no separation of passenger region and track region is arranged. The construction is characterized in that the sliding doors have a self-supporting embodiment and are guided to move in or on the stationary regions with provision of an upper and lower guide and one guide is embodied as a roller guide or ball bearing linear guide and one guide is embodied as a slide guide or roller guide.
