Rail Dog Spike Fastening System
Railway Dog Spikes are traditional cut-spike fasteners forged from medium carbon steel, featuring a rectangular shank with a chisel point and an offset L-shaped head. These spikes are driven through tie plates into wooden sleepers, where the offset head engages the rail base while the tapered point minimizes timber splitting. Their simple design enables rapid installation using spike mauls or mechanized drivers.

Installation & Maintenance Perspective:
- Driven vertically using manual spike mauls
- Pneumatic drivers enable high-speed installation
- Pre-drilled pilot holes reduce timber stress
- Consistent spacing ensures uniform load distribution
- No threading or torque requirements simplify process
Maintenance & Operational Perspective
- Square shank resists rotation in wood fibers
- Tapered point guides straight entry into sleeper
- Head offset designed for standard tie plate profiles
- Works with hardwood and softwood sleepers
- Pull-out resistance increases with wood density
