Sep 30, 2025

A rail spike, also known as a cut spike or crampon, is a large nail which is used to fix rails fastening system to railroad in the track. The main function is to keep the rail in gauge.


A dog spike, also called cut track spike, is often used to fasten T-shaped railway track to wooden sleepers, to secure a rail and tie plate to the ties in track, which has a pointed penetrating head with square shank, and the underside of the spike head is sloped to compromise the top of the rail base.

In railway construction and maintenance, correct use of dog spikes is crucial for securing rails and ensuring track stability.

First, it is important to select spike specifications that match the thickness of the wooden sleeper and the rail type. Spikes that are too short or too thin may result in insufficient holding force, while spikes that are too long or too thick could damage the sleeper.

Second, proper installation procedures must be followed. Dog spikes should be driven vertically into the sleeper, with the spike head tightly pressing against the rail plate to ensure firm contact between the rail and the sleeper. Specialized hammers or spike-driving machines should be used during installation to avoid tilting or damaging the sleeper, which could affect the holding force and track level. In addition, the spacing between spikes should be even to ensure uniform force distribution along the rail.

Furthermore, regular inspection and maintenance are key to ensuring long-term effectiveness. Over time, spikes may loosen due to vibration, sleeper aging, or corrosion. Loose, bent, or rusted spikes should be replaced promptly to maintain the stability and reliability of the rail fastening system.
