ABSTRACT:
A rail fastener for fastening rails to a support structure, particularly adapted for use in switches, crossovers, frogs and the like where a track plate must support a pair of closely spaced or nonparallel rails. The rail fastening includes a rigid track plate to which the rail is adjacent and two fastener pads laterally spaced on the track plate and disposed between the track plate and the support structure. Each fastener pad has a rigid member and a resilient member bonded together and two pins to join the elastomeric member to the track plate.
