Rail track insert assembly for use between rails and adjacent road surfaces in a road level rail bed comprising resiliently flexible elongate members engaging, respectively, with the rail and the adjacent road surface and defining a generally vertical slip plane at their interface, to accommodate vertical movement of the rail in response to the passage of rail car wheels, while sealing against intrusion of surface water and detritus. An elongated channel defined in the under surface of each of the insert members accommodates rail clips securing the rail to the underlying track bed.

A rail track surface structure insert assembly for use in the space defined between a track rail and an adjacent road surface, wherein said rail is secured to a rail bed by rail clips, and comprises a rail head, rail base and an intermediate web connecting said rail head and the rail base and having a gauge side and a field side, said insert assembly comprising, in combination: a longitudinally extending first rail insert member having a top surface, a bottom surface, a rail-engaging side surface and an opposite side surface, said top surface adapted to lie in the general plane of the top surface of said rail head; said bottom surface sealingly registering with the upper surface of the base of said rail; said rail engaging side surface contoured to sealingly register on a major portion thereof with said web of said rail and on a minor portion thereof to sealingly register with the side of the head of said rail; said opposite side surface including a generally vertical planar surface when the first rail insert member is installed in registering contact with said rail; a longitudinally extending second insert member having a top surface, a bottom surface, a road surface-engaging side surface and an opposite side surface, said top surface adapted to lie in said general plane of the top surface of said rail head when installed in registering contact with said first rail insert member; said bottom surface sealingly registering with the underlying rail bed; said road surface-engaging side surface adapted to fixedly and sealingly register with said adjacent road surface; and said opposite side surface including a vertical planar surface adapted to sealingly register with said vertical planar surface of said first rail insert member, thereby to provide a slip plane to accommodate relative movement of said first rail insert member with said second insert member consequent on the vertical flexing movement of said first rail insert member and said adjacent track rail in fixed registration therewith.
