Rail E Clip Fastening System
The Railway E-Clip is a forged elastic rail fastening made from high-grade spring steel. Its unique E-shape geometry provides constant toe load to hold rails against sleepers under dynamic train forces. Without bolts or threads, it relies on elastic deflection to absorb vibrations, resist rail creep, and maintain gauge stability. It is widely used in heavy-haul, passenger, and transit tracks worldwide.
Technical Specifications:
| Parameter | Description | Typical Value |
|---|---|---|
| Material | Spring steel per EN 10089 or equivalent | 60Si2Mn / 51CrV4 |
| Wire diameter | Standard round bar diameter | 16 mm – 20 mm |
| Toe load | Clamping force per installed clip | 10 – 14 kN |
| Fatigue life | Cycles before fracture risk | ≥ 5 million |
| Application rail types | UIC / BS / AREMA profiles | UIC54, 115RE, BS113A |
| Surface finish | Corrosion protection type | Oil dip / Zinc plated |
| Operating temperature | Ambient track range | -40°C to +60°C |
Installation & Maintenance Perspective:
- Maintains clamping force even after millions of wheel load cycles.
- Prevents rail overturning and gauge widening on sharp curves.
- No gradual loosening like bolted systems – elastic design is self-locking.
- Withstands sudden impact loads without brittle fracture.
- Fail-safe design: visible loss of clip indicates need for replacement.
Maintenance & Operational Perspective
- One-piece construction eliminates loose small parts on site.
- Installed using a hydraulic or manual tensioner tool only.
- No torque wrench or tightening calibration required during application.
- Can be removed and reused if deflection remains within limits.
- Prevents incorrect assembly due to simple geometry orientation.
