A rail pad, also called rail rubber plate, is designed between the rail tie plate and foot of the rail, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting. Its defined stiffness is used to increase the elasticity of the superstructure of the ballast and reduce shock and vibration in the rail system.
It's always fastened within a fastening system by screw spikes or rail bolts into the sleeper ties.
Rail Rubber Pads for E-type Rail Fastening Systems
Rail rubber pads used for E-type rail fastening systems have similar functions of the rail insulators to insulate the rail above it from the tie sleepers lied below it, for effective protection against vibration and structure-borne noise as well. The rail pad works together with e-clips, rail insulators/insulated gauge blocks and rail shoulders/embedded parts to form a whole set of E-type rail fastening system.
