ABSTRACT:
A pad, suitable for spacing the bottom of a railway rail from a rail foundation on which the rail stands, comprises a plate-like rail-supporting portion (1), made of cushioning material, having an upper main face supporting the rail and softer, resiliently-deformable, sealing portion (3) located at a peripheral region of the lower main face of the rail-supporting portion (1). When the pad is placed on a rail foundation and a rail is placed on the upper main face of the rail-supporting portion (1), the sealing portion (3) deforms under the weight of the rail so as to form a substantially watertight seal, between the rail foundation and the pad, around the periphery of the pad.
