The dog spike fastening system (also known as a cut track spike) is a simple, cost-effective method primarily used to secure T-shaped rails and tie plates to wooden sleepers. It is characterized by an offset "L-shaped" head with two side lugs that resemble a dog's head, which aid in spike removal using specialized pullers.
Signum Rail Fastening offers rail fasteners for dog spike systems, providing comprehensive one-stop services.
Design: Features a square shank and a wedge-shaped tip (rather than a point).
Installation: The spike is driven into the wooden sleeper with its flat edge perpendicular to the grain to maximize friction and resistance against loosening.
Primary Purpose: Its main function is to maintain track gauge by preventing the rail from shifting laterally, rather than providing high vertical clamping force.
Common Sizes: Standard specifications include 5/8" × 6" and 9/16" × 5-1/2".
While both secure rails to sleepers, they differ significantly in application and performance:
Usage Areas: Widely used in North America due to the extensive use of timber sleepers on freight lines. It is also common in industrial sidings, mining tracks, and light rail.
Maintenance: In high-traffic areas, dog spikes tend to "back out" or work loose over time, requiring periodic inspections and re-driving.
Timber Protection: To prevent the wood from splitting during installation, holes are often pre-bored, or steel bands are added to the sleeper ends.
