Rail Dog Spike - Technical Specification & Identification
| Parameter | Description & Details |
|---|---|
| Product Name | Dog Spike (or Rail Road Spike) |
| Common Names | Dog Spike, Cut Spike, Track Spike |
| Primary Function | To secure flat-bottomed rail to timber sleepers (ties) and to hold the tie plate in position. |
| Application | Exclusively for use with Timber Sleepers (Wooden Ties) and Flat-Bottom Rail. |
| Standard Material | Low-Carbon Steel (e.g., AISI 1020, 1022). Must be malleable to withstand driving impact without shattering. |
| Material Standard | AREMA (AREA): M92 (Chemical) & M103 (Physical). ASTM: A65 (Standard Specification for Railroad Spikes). |
| Heat Treatment | Generally not heat-treated. The as-rolled or as-forged condition provides the necessary ductility. |
Rail Dog Spike - Application, Handling & Comparison
| Aspect | Details |
|---|---|
| Installation Method | Driven with a spike maul (sledgehammer) manually or by a power spike driver (automated machine). |
| Installation Process | The spike is driven through the hole in the rail base and into the pre-drilled hole in the timber sleeper. The protruding point is often clinched (bent over) for extra holding power. |
| Holding Mechanism | Primarily friction and shear strength of the compressed wood fibers. The rectangular head prevents rotation. |
| Key Advantages | - Simplicity: Simple, robust, and inexpensive design. - Proven Reliability: Centuries of proven use on timber sleepers. - Ductility: Can be clinched and re-clinched during maintenance. |
