Rail Clamps vs. Other Railway Systems
| Feature | Rail Clamps | Fish Plates (Joint Bars) |
|---|---|---|
| Primary Function | To provide strong longitudinal restraint/anchorage and prevent rail creep. | To splice and connect the ends of two adjacent rail sections. |
| Mechanical Principle | Clamping force applied directly to the rail head (like a vice). | Bolted connection constraining the web of two rail ends. |
| Forces They Resist | Primarily Longitudinal (extremely high resistance to rail movement). | Vertical and Lateral at the joint itself. |
| Typical Location | Specific points: bridge ends, expansion joints, steep grades, sharp curves. | At the ends of rail sections (joints). |
| Key Advantage | Provides massive longitudinal force without damaging the rail. Can be retrofitted. | Allows for thermal expansion and is essential for repairs and insulated joints. |
| Key Disadvantage | Not a standalone system; works in conjunction with standard fasteners. | Creates a weak impact point in the track, leading to higher maintenance. |
