Railway Fastclip System
| Feature | Description & Specifications | Notes / Purpose |
|---|---|---|
| Product Name | Fastclip, Vossloh Fastclip System | A proprietary and patented fastening system. Often used as a generic term for similar designs. |
| Primary Function | To elastically clamp the rail to a concrete sleeper (tie) or slab track base, providing vertical and lateral restraint, electrical insulation, and vibration damping. | The core of a modern, high-performance rail fastening system. |
| Application | Used in high-speed lines, heavy-haul corridors, metro systems, and mainline tracks worldwide. Designed for use with monoblock concrete sleepers. | Known for its reliability and performance in demanding applications. |
| System Components | 1. Fastclip (the spring clip itself) 2. Shoulder / Housing (cast into the sleeper) 3. Baseplate (or sole plate) 4. Insulators (plastic components for electrical isolation and padding) 5. Rail Pad (elastomeric pad under the rail) |
The clip works as part of an integrated system. Its performance depends on all components. |
Comparison: SKL Clip vs. Fastclip
Both are modern elastic rail clips but with key differences:
| Aspect | SKL Clip | Fastclip |
|---|---|---|
| Installation Method | Pushed vertically down into the shoulder. | Rotated 90 degrees into place. |
| Tooling | Applicator/Remover tools that work on the legs. | Tool that grips the clip body and twists it. |
| Geometric Shape | More traditional "U" or "V" shape with long legs. | Distinctive "W" or "Double-Z" shape. |
| System Origin | Common in German and European networks. | A proprietary Vossloh design, now a global standard. |
| Reusability | Good, if removed carefully. | Excellent, designed specifically for easy reuse. |
