Rail Jointing and Fastening Systems
| Feature | Fish Plate (Joint Bar / Splice Bar) |
|---|---|
| Primary Function | To splice and connect the ends of two adjacent rail sections. |
| Component Type | A joining component. |
| Location on Track | At the ends of rails (joints). |
| Key Advantage | Allows for thermal expansion/contraction. Essential for repairs, insulated joints, and expansion points. |
| Key Disadvantage | Creates a weak point in the track. Causes impact loads, noise, vibration, and higher maintenance. |
| Maintenance Requirement | High. Bolts can loosen, and the joint and underlying sleepers degrade faster due to impact forces. |
| Typical Application | Older networks, sidings, specific joints (insulated, expansion), and temporary repairs. |
