Advantages of Railway Fast Clips
The following table outlines the key advantages of the Fast Clip system.
| Advantage | Description |
|---|---|
| Simple and Robust Design | The clip has a simple, one-piece design with no small parts. This robustness makes it highly reliable and resistant to damage during handling and installation. |
| Excellent Vibration and Shock Absorption | The clip's elasticity effectively dampens vibrations and absorbs dynamic impacts from trains, protecting the track foundation and reducing noise levels. |
| Ease of Installation and Removal | Fast Clips can be installed and removed quickly using a simple hydraulic or pneumatic tool that stretches the clip and places it over the shoulder of the baseplate. This allows for high productivity in track laying and maintenance. |
| Proven Performance in Heavy-Haul & High-Speed | This system is a global standard suitable for a wide range of applications, from heavy-haul mining railways to high-speed passenger lines, demonstrating its versatility and reliability under extreme loads. |
| Good Electrical Insulation | When used with insulated baseplates and shoulder inserts, the Fast Clip itself does not create an electrical bridge, making it well-suited for tracks with signaling systems that use track circuits. |
| Long Service Life | Made from high-carbon spring steel and properly heat-treated, Fast Clips offer high fatigue resistance, leading to a long operational lifespan with minimal maintenance. |
| High Longitudinal Restraint | The generated friction provides significant resistance against rail creep caused by thermal expansion and train braking forces. |
Comparison with SKL Clips
| Feature | Fast Clip (Nabla Clip) | SKL Clip |
|---|---|---|
| Visual Shape | Inverted "V" or Nabla (∇) shape. | A more complex "Z" or "S" shape. |
| Installation Method | Stretched and placed over a shoulder on the baseplate. | Pushed and twisted (rolled) into a housing on the shoulder. |
| Typical Application | Often used with baseplates on concrete sleepers. | Often used in a shoulder/housing system integrated into the sleeper. |
| Key Characteristic | Known for high initial toe load and simple, robust design. | Known for consistent holding force and excellent fatig |
