Rail Spikes

Rail spikes provide a mechanical interlock that offers over twice the holding power of traditional hammered railway spikes. They primarily include dog spikes and screw spikes.

Dog Spike / Cut Track Spike

The dog spike, also known as a cut track spike, is shaped like a dog’s head and is used to fasten T-shaped rails to wooden ties. Its head is sloped to match the rail flange, and the wedge-shaped tip is driven into the tie across the grain, which enhances its holding power significantly.

The square cross-section of a dog spike provides about 50% more holding strength compared to a circular spike of the same metal quantity. When driven across the grain, a dog spike can achieve approximately double the holding power compared to one driven with the grain. Early tests showed that pulling out a 9/16” × 9/16” spike driven 4¼ inches into dry cedar required an average force of 857 pounds, while in seasoned oak, it required 4281 pounds.

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.
