A system for bridging a gap between a platform having an elevated surface, and a transport vehicle that has an internal floor and a side door. The system includes a device mounted beneath the doorway of the side door such that an upper edge of the device that is adjacent the first elongate side is approximately level with the internal floor. The device has a longitudinal support body that is resiliently compressible and includes a plurality of overlapping leaf members. When the support body is in an uncompressed state, the device projects outwardly from the side of the vehicle whereby, when the transport vehicle is suitably positioned beside the platform, the device engages the platform such that the support body is compressed and the overlapping leaf members provide a bridging surface between the elevated surface and the internal floor.
