Rail Dog Spike Fastening System
The Railway Dog Spike is a traditional forged steel fastener used extensively in timber sleeper track systems. Its distinctive hooked head provides secure leverage for driving and extraction while preventing rail creep. Manufactured from carbon steel with controlled hardness, this spike establishes retention through displacement of wood fibers during installation. Its century-proven design remains essential for heritage railways and secondary track applications worldwide.

Installation & Maintenance Perspective:
- Serves as primary fastener for North American and colonial railway construction since 1800s.
- Remains specified for heritage railways requiring authentic period-correct materials.
- Represents foundational track technology still taught in railway engineering programs.
- Continues use in secondary lines where modernization investment remains limited.
- Preserves traditional tracklaying skills passed through generations of railway workers.
Maintenance & Operational Perspective
- Driven perpendicular to sleeper surface ensuring vertical alignment through rail base.
- Creates permanent wood fiber displacement that forms tight interference fit.
- Achieves maximum holding power when driven one-eighth inch below rail base.
- Maintains retention through seasonal wood expansion and contraction cycles.
- Provides visual confirmation of proper installation through consistent head orientation.
