Anticreeper
anticreeper
[′an·tē‚krēp·ər]Anticreeper
a clamp that is attached to the flange of a railroad rail and rests on a tie; it is part of the track superstructure when spikes are used for fastening the rail and tie. Anti-creepers inhibit the lateral displacement of the rails caused by the action of the wheels of the rolling stock. They are not used with reinforced-concrete ties.
