<p>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 includes a bridging plate (58) and a mounting arrangement for mounting the bridging plate between the railway rail and the ground surface. In use, the mounting arrangement permits displacement of the bridging plate between two positions - a first rest position in which said bridging plate extends between respective upper surfaces of the railway rail and the ground surface; and a second displaced position in which said bridging plate is displaced below the first position in which the plate does not interfere with the passage along said railway rail of a wheel of a railway vehicle. The mounting arrangement is operable to permit displacement of said bridging plate from the first position to the second position under a railway vehicle load imposed on the bridging plate by engagement of the bridging plate by the wheel (1) of a railway vehicle, and to substantially maintain the first position when the bridging plate is engaged by a load substantially less than that of the railway vehicle load.</p> |
