Rail clips are critical components of the railway fastening system. Their main function is to firmly secure the rail onto sleepers or rail slabs through elastic pressure, while also providing flexibility to absorb shocks and vibrations generated by passing trains. To achieve the best performance, rail clips must be used and installed correctly.
In practical applications, rail clips are installed in combination with embedded shoulders or base plates on sleepers, ensuring that the bent section of the clip precisely presses against the rail foot. During installation, specialized tools must be used to apply the correct force. The clamping force should be strong enough to prevent both lateral and longitudinal rail movement, but not excessive, as over-tightening may cause permanent deformation of the clip or reduce its fatigue life.

Rail clips are typically manufactured from high-strength spring steel, offering excellent fatigue resistance. However, improper installation or uneven loading can compromise their elasticity and reduce the clamping force, negatively affecting rail stability.

| 0.56-0.64 | 1.4-1.8 | 0.4-0.7 | ≤0.035 | ≤0.035 | 0.35 | 0.35 | 0.25 |
Regular inspection and maintenance are also essential. Rail clips should be checked for wear, corrosion, or loosening, and damaged parts must be replaced promptly. This is particularly important for high-speed and heavy-haul railways, where rails are subjected to greater stress. A failed clip may lead to gauge deviation or even track damage. Correct use of rail clips not only ensures stable railway operations but also extends the service life of sleepers and rails.
