ABSTRACT:
The subject spike has a rectangular shank having a front surface which faces the rail when the spike is driven into place, a back surface opposite the front surface and two side surfaces. There is a ledge on one side, perpendicular to the length of the spike. The ledge has a face facing the head of the spike and a distance from it such that when the spike is fully driven the ledge engages the underside of the plate which supports the rail. The other side of the shank is contoured to provide clearance for the ledge to pass through a standard sized hole in the plate and then to cam the spike sidewise to engage the ledge under the plate. This engagement attaches the rail flange to the plate and the spike helps attach both the rail and plate to the tie.
