Technical Parameters
Railway Dog Spikes
| Feature | Description |
|---|---|
| Primary Function | To fasten flat-bottomed rails to wooden sleepers. |
| Key Characteristic | A chisel or duck-bill point that leverages the wood's grain for a secure hold, resisting upward (pull-out) and lateral forces. |
| Common Standards | AREMA (American Railway Engineering and Maintenance-of-Way Association), BS (British Standards), various international railway standards. |
| Typical Materials | Medium Carbon Steel (most common), High Carbon Steel, sometimes Corrosion-Resistant Steels. |
| Common Coatings | Galvanization (zinc coating), Black (uncoated). |
Detailed Specifications Table
This table provides more detailed technical information on common spike types and dimensions.
| Spike Type / Common Name | Typical Size (Shank Dia. x Length) | Head Dimensions (Approx.) | Typical Application / Notes |
|---|---|---|---|
| Standard Dog Spike | 5/8" x 5 1/2" | 1 1/2" x 1 1/8" | The most common size for general mainline and branch line track. |
| Heavy Dog Spike | 3/4" x 5 1/2" | 1 5/8" x 1 1/4" | Used in areas requiring higher holding power, such as curves, heavy-haul lines, or bridge timbers. |
| Light Dog Spike | 1/2" x 5" | 1 3/8" x 1" | Used for lighter-duty applications, such as industrial sidings or yard tracks with less traffic. |
Comparison with Alternative Fastenings
| Fastening Type | Description | Key Difference from Dog Spike |
|---|---|---|
| Dog Spike | A simple nail-like fastener for wood sleepers. | The baseline technology. Relies on crushing wood fibers for grip. |
| Screw Spike | A large, heavy-duty screw threaded into the sleeper. | Provides significantly higher pull-out resistance. Used where track stability is critical (e.g., bridges, curves). More expensive and slower to install. |
| Elastic Fastener (e.g., Pandrol® clip, e-clip) | A spring-steel clip that applies a consistent clamping force. | Used with concrete sleepers or baseplates on wood sleepers. Provides superior elasticity, allowing the rail to expand/contract while remaining secure. This is the modern standard for mainline railways. |
