Description
Technical Parameters
Railway fishplates are used as fasteners to connect rails to rails
Key Features
| Aspect | Description |
|---|---|
| Design | Symmetric or asymmetric plate structure with 4–6 bolt holes, contoured to fit the rail web. |
| Installation | Paired on both sides of the rail joint, secured with high-strength bolts. |
| Primary Functions | 1. Mechanically joins rail ends; 2. Distributes wheel load stresses; 3. Controls rail gap expansion; 4. Provides electrical insulation (if insulated type). |
| Failure Modes | Bolt loosening, cracks, wear, or insulation degradation (for insulated fishplates). |
