Abstract
A railway crossing installation for a pair of spaced-apart elongated rails each having a transverse section, a bottom horizontal flange, a vertically extending bight and a top ball. A plurality of relatively elongated concrete gauge panels are provided, with each gauge panel having a top surface generally aligned with the ball upper surface, each gauge panel having elongated sides disposed adjacent the rails and ends disposed in confronting relation to any adjacent gauge panels. The gauge panel side adjacent a rail has an integral elongated projection spaced below the panel top surface, with the projection extending towards the bight. A resilient, elongated extrusion extends along each gauge panel side between the projection side and the rail bight, the extrusion being selectively removably secured to the projection so that the outer ends of the extrusion is closely adjacent the associated rail. The installation also includes concrete field panels positioned outwardly of each of the rails. The inner sides of the field panels have a resilient seal secured thereto which extends towards the associated rail.
