The pad (10) is a composite pad and comprises an elastomeric pad (30) and bonding means (40) bonded together to resist releasable movement between them. The bonding member (40) galvanised, powder-coated, steel plate or a rigid polymeric film or sheet, an acrylic layer. An adhesive layer (18), such as a methacrylate ester, is used for bonding the elastomeric pad (30) and the bonding member (40) to the railroad tie (14). The bond means may be formed as a particular layer (40') bonded to the elastomeric pad (30). <IMAGE>
