  • Bridging platform arrangement
    Patent number: 7073726
    Abstract: The invention relates to a bridging platform arrangement (20) for bridging a gap (16) between a railway rail (10) and an adjacent ground surface (14). The bridging platform arrangement (20) includes a bridging plate (58) and a mounting arrangement for mounting the bridging plate (58) between the railway rail (10) and the ground surface (14). In use, the mounting arrangement permits displacement of the bridging plate (58) between two positions—a first rest position in which the bridging plate (58) extends between respective upper surfaces of the railway rail (10) and the ground surface (14); and a second displaced position in which the bridging plate (58) is displaced below the first position so as to not interfere with the passage along the railway rail (10) of a wheel (1) of a railway vehicle.
