Functional Comparison
| Feature | Dog Spike | Standard Spike |
|---|---|---|
| Head Design | Flat with hook (anti-loosening) | Round or square (no hook) |
| Fastening | Hooks under rail base | Relies on friction only |
| Lateral Resistance | High (due to hook) | Moderate |
| Installation | Requires pre-drilling in wooden sleepers | Can be driven directly (in soft wood) |
| Typical Use | Traditional railways, heritage lines | Temporary tracks, light-duty lines |
Installation & Maintenance
| Step | Requirement | Tool/Method |
|---|---|---|
| Pre-Drilling | Hole diameter: 80% of spike shank | Electric drill with wood bit |
| Driving Angle | 10°-15° inward tilt toward rail center | Spike maul + angle guide |
| Torque | 30-50 N·m (for re-tightening) | Torque wrench (if applicable) |
| Inspection | Check for loosening every 6 months | Visual + hammer test (sound check) |
