The LOCK SPIKES shown on this page are the most effective fasteners for maintaining true line and gauge at low cost.
TIE PLATE LOCK SPIKES employ spring compression to hold tie plates firmly in place on cross ties and bridge timbers. They can be driven with standard track tools. Spikes are placed on the diagonally opposite hold-down holes of the tie plate and driven in prebored holes in the tie. Holes of 9/16 in. diameter are drilled to a depth of 7 in. below the top of the tie plate. Spikes are available in 6 in. or 7 in. lengths.
Two lock spikes normally are used in conjunction with two standard cut spikes in each tie plate.
SPTING ACTION REDUCES WEAR. When driven to refusal, approximately 1 in. above the tie plate, the spread shank of the tie plate lock spike is compressed approximately 1/16 in. by the walls of the hole, and the diverging sides of the head are wedged into the tie plate hole. Play between the spike and the hole is eliminated, and the plate is restricted from horizontal or vertical movement under spring pressure. This spring action provides tight adherence between the tie plate and the tie, virtually eliminating tie wear under plates.
