Abstract: An apparatus for dynamically filling a gap between a side of a railway train car and an adjacent edge of a station or loading platform for preventing accident or injury to passengers while boarding or alighting from the train. A plurality of flexible, flat planar sheet-like members project outwardly from a vertical platform edge surface that is confrontingly opposed to the side of a railway train car located adjacent to the platform. The extension of the projecting members from the platform is such that as an approaching train traveling along a track moves into proximity with the platform, the train contacts at least the free ends of the projecting members whereby the members are thereby resiliently deflected to assume a generally bent contour in the direction of train movement and thereby substantially fill the gap between the platform edge and the side of the train.
