The present invention contemplates a resilient pad mounted on the outside adjacent portion of a rail having sealing engagement with the rail along its base, the head and the interconnecting web of the rail with compression chambers located within the pad to permit the resiliency of the pad to cooperate with the movement of the rail in its vertical displacement as well as other movements imparted thereto by the passage of trains, thereover while maintaining a sealing contact with the rail to prevent water collecting along the rail and other foreign matter to minimize maintenance.

A rail crossing structure comprising a supporting means for supporting the rail crossing structure; at least a pair of spaced rails mounted on said supporting means; each of said rails having a head, a base and an intermediate web interconnecting said base and said head; a longitudinally extending resilient pad mounted on one side of each of said rails; each of said pads having a plurality of bores extending longitudinally therethrough; each of said pads having an upper surface, a lower surface and two contoured side surfaces; said lower surfaces sealingly abuttingly contacting said base of said rails; said upper surfaces lying in the same general plane of the top of said rails; one of said sides of each of said pads having a major portion thereof in sealing and abutting contact with said intermediate web of said rail; the upper portion of said one side of each of said pads being generally planar and in abutting contact with said head of said rails; and the juncture of each said upper planar portions of said pads and said major portion of said one side of said pads in contact with said intermediate web being recessed to define a longitudinally extending channel with an upwardly disposed lip and a compression chamber in cooperation with said rail.
