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) and softer, resiliently-deformable, sealing means (3), which sealing means (3) are bonded to the rail-supporting portion (1) at a peripheral region thereof and are such that, when the pad is placed on a rail foundation and a rail is placed on the rail-supporting portion (1) of the pad, those means (3) deform under the weight of the rail so as to form a substantially watertight seal around the said peripheral region of the rail-supporting portion (1).
