A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.

A railroad rail track pad composition including a particular ethylene.Math.-olefin.Math.non-conjugated polyene random copolymer (A), clay (B), and a sulfur atom-containing silane coupling agent (C) is used in order to lower the viscosity of a rubber composition that is a raw material for molding while suppressing lowering of the rubber elasticity of a crosslinked and molded product to be obtained. In addition, a molded product obtained by crosslinking the composition, particularly a molded product obtained by crosslinking and foam-molding the composition, is provided with rubber elasticity that is suitable as a railroad rail track pad.

An interface pad for a concrete tie includes a resilient contact pad to cushion the tie from any overlying parts in a railway application, such as panels in a grade crossing or rails in a turnout. The pad may be flat or a cupped shape and may be of varying size to accommodate varying tie widths. The invention further comprises means and methods to correctly secure such an interface pad to a concrete railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the tie.

This disclosure relates to a rail pad including a pad matrix having a first material and at least one damping element at least partially encapsulated or embedded in the pad matrix. The damping element includes a second material. The second material includes at least one damping element having a damping factor tan delta greater than or equal to 0.5 in the audible frequency of 1000 Hz. Methods for producing the rail pad are also disclosed.

An under sleeper pad (1) for fastening to an underside, situated opposite rails (2), of a sleeper (3), with the under sleeper pad (1) having at least one first, preferably porous material component (4) and at least one second porous material component (5) different than the first material component (4), the first material component (4) being more elastic than the second material component (5) and the second material component (5) being more plastic than the first material component (4), the first material component (4) being arranged exclusively in a first layer (6) of the under sleeper pad (1) and the second material component (5) being arranged exclusively in a second layer (7) of the under sleeper pad (1).

A rubber pad is configured to be arranged between a sleeper of a track and a rail of the track. The pad has a flat portion with a width substantially the same as a width of the sleeper; the flat portion comprises a plurality of holes.
