Abstract:
A railway crossing structure assembly useful in a road-level railway crossing in which a pair of rails secured to a rail bed, which includes rail ties and an underlying tie bed, each of said rails having a gauge side and a field side,wherein said rails are secured to said rail ties and each of said rails comprises a rail head having a top surface, a rail base having an upper surface, and an intermediate web, each of said rails being adapted for limited vertical movement upon intermittent loading and unloading of the rail upon passage of a rail load thereon, said assembly comprising, when installed in operative condition, in combination: longitudinally extending resiliently flexible gauge side rail insert members, each having a top surface generally lying in a plane of the top surface of said rails, a bottom surface registering with the upper surface of a rail base, a rail-engaging side surface contoured to sealingly and fixedly register with said web on the gauge side of said rail in order thereby to move vertically with limited movement of said rail, and an opposite side surface including a planar surface inclined downwardly and outwardly away from an adjacent rail at a minor angle to a vertical plane when installed in operative engagement with said rail, a longitudinally extending center gauge panel comprising a rigid slab having a top planar road surface generally lying in a plane of the top surfaces of said pair of rails, a bottom surface engaging with said tie bed, and side surfaces including an inclined planar surface adapted to closely register in tight compressive contact with an inclined planar surface of each of said gauge side insert members when said rails are in unloaded condition and to register in looser compressive contact with the inclined planar surface of each of said gauge side insert members when said rails are in loaded condition.
