摘要:
In a railroad system a track includes ties positioned at predetermined intervals and supporting a pair of rails. Shoulders are disposed in pairs adjacent to the sides of each rail and are partially imbedded in the ties to limit the lateral movement of the rails and define the track gauge. Over time, friction between the insulators and the shoulders may cause excessive wear and a gap therebetween. This wear is compensated by a shim attached to the shoulders.
