rail spike

Rail spikes provide a mechanical interlock that delivers more than twice the holding power of conventional hammered railway spikes. Rail spikes mainly includes dog spike and screw spike.

Dog Spike / Cut Track Spike

Dog spike , also called cut track spike, and as the name implies, dog spike looks like a dog's head, which is mainly used on T-shaped rails to fasten T-shaped railroad track to wooden ties that have an L-shaped head and a square shank. The bottom of the head is sloped to match the slope of the flange of a rail and the tip is wedge-shaped, not pointed. The wedge is driven into the tie across the grain, which means the wedge is parallel to the track. The square cross section gives a railroad dog spike much higher holding strength than a fastener having the same amount of metal but a circular cross section has; roughly speaking, about 50% more.

dog spike

Dog spike with the wedge driven across the grain will have about twice as much holding power as one driven with the grain. Early experiments showed that pulling out a 9/16” × 9/16” spike driven 4¼ inches into dry cedar required on average a force of 857 pounds. In seasoned oak, another experimenter needed 4281 pounds. Below is the technical data of dog spike.

Screw Spike

Screw spikes are commonly used to fasten timber railway ties/sleepers; however, they can also be used in conjunction with plastic ferrules that have been cast into concrete ties/sleepers.
