Dog Spike Models & Specifications
Dog spike models are primarily differentiated by their size, weight, and the standard they conform to. The "model" is often defined by its dimensions.
| Model / Standard Reference | Size (Length x Shank Dimension) | Theoretical Weight (approx. per 1000 pcs) | Material & Finish | Primary Application |
|---|---|---|---|---|
| Standard Size | 130 mm x 16 mm x 16 mm (Square Shank) | 165 kg | Low/Medium Carbon Steel, Galvanized | Most common type for general track on wooden sleepers. |
| Large Size | 150 mm x 19 mm x 19 mm (Square Shank) | 225 kg | Low/Medium Carbon Steel, Galvanized | For heavier duty applications, curves, or softer wood. |
| Small Size | 115 mm x 14 mm x 14 mm (Square Shank) | 120 kg | Low/Medium Carbon Steel, Galvanized | For light-duty tracks or temporary lines. |
| AREMA (US) 4-3/4" | 121 mm (4.75 in) long | 135 lbs (61 kg) | Steel, typically galvanized. | Follows American Railway Engineering and Maintenance-of-Way Association standards. |
| Indian Railway Spec | 125 mm - 140 mm long | Varies | Steel, galvanized. | Designed to meet specifications of Indian Railways. |
Dog Spike vs. Other Railway Fastening Systems)
| Feature | Dog Spike (Cut Spike) | Screw Spike | Elastic Rail Clip (e.g., Pandrol, Nabla) |
|---|---|---|---|
| Primary Function | To anchor the rail baseplate to wooden sleepers by friction and grip. | To screw into the sleeper and clamp the baseplate/rail with higher force. | To provide a spring-loaded, elastic grip on the rail foot. |
| Mechanical Principle | Friction and Wood Fiber Compression (like a nail). | Threaded Engagement (like a screw). | Continuous Elastic Tension and clamping force. |
| Holding Power | Moderate; can work loose over time due to vibration and wood decay. | High pull-out and lateral resistance. | Excellent and Consistent; self-adjusting under load. |
