Rail dog spike Fastening System
Railway Dog Spikes are L-shaped steel fasteners driven through tie plates into wooden sleepers to secure rail position, featuring a sharp rectangular point and an offset head that grips the rail base. These carbon steel components provide both vertical hold-down and lateral restraint through friction and embedment, with the distinctive dog-eared head profile allowing for visual inspection of spike condition and withdrawal indication.
Technical Specifications:
| Spike Type | Shank Section | Head Style | Typical Pull-out Resistance |
|---|---|---|---|
| Standard Dog | 14-16mm square | Offset rectangular | 8-12 kN in hardwood |
| Screw Spike | Threaded round | Square drive | 25-35 kN |
| Spring Spike | Oval/rectangular | Notched | 10-15 kN |
| Drive Spike | Round fluted | Domed | 15-20 kN |
| Material | Q235/45# steel | 370-550 MPa tensile | Plain or coated |
| Inspection | Visual head check | Hammer test | Gauge measurement |
Installation & Maintenance Perspective:
- Used continuously since early railway development
- Standardized dimensions established in 19th century
- Original fastening system for wooden sleeper tracks
- Preserved in heritage railways worldwide
- Manufacturing methods refined over 150+ years
Maintenance & Operational Perspective
- Offset head applies downward force on rail base
- Shank friction provides primary withdrawal resistance
- Multiple spikes per sleeper distribute loads
- Tie plate holes ensure consistent positioning
- Lateral forces resisted by shank bending strength
