A rail track insert assembly for use in road-level railway crossings having a pair of rails secured to a rail bed, each of the rails having a gauge side and a field side, a rail base and an intermediate web and being adapted for limited vertical movement upon intermittent loading of the rail upon passage of a load on the rail, the assembly comprising a longitudinally extending flexible gauge side rail insert member having a top surface in the plane of the rail head and a bottom surface registering with the base of the rail, a rail-engaging side surface sealingly and fixedly registering with the web on the gauge side in order to move with the limited movement of the rail, and an opposite side surface including a planar surface inclined downwardly and outwardly away from the adjacent rail at a minor angle, a longitudinally extending center gauge panel comprising a rigid slab having a top planar road surface lying in the general plane of the top surfaces of the rails, a bottom surface engaging with the tie bed, and side surfaces including an inclined planar surface registering in tight compressive contact with the inclined planar surfaces of each of the first rail insert members when the rails are in unloaded condition and to register in looser compressive contact with each of the inclined planar surfaces of the insert member when the rail is in loaded condition.
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,
A combination of a fixed rail, a resiliently flexible rail insert member and a panel member, wherein
