As a part of railway fastening system, rail clip is designed for resulting in the role of buckle pressure on the track by bending and twisting. Elastic rail clip is a reliable connection between steel rails. Main rail clip function is as possible as ensure integrity of railway track. In summary, elastic rail clips are used to prevent vertical and horizontal movement of steel rail relative to the railway sleeper. And then, rail clip ensure the normal gauge, so as to ensure the safety of rail vehicles.
According to different standards and applications, Rail clips can be divided into various types. The common elastic railway clip types include SKL clip, E-type rail clip, Deenik clip, Nabla clip and etc.

What is the primary purpose of elastic rail clips (ERC)?
The primary purpose of Elastic Rail Clips (ERCs) is to securely fasten steel rails to sleepers (ties) and maintain the correct track gauge, preventing unwanted vertical, lateral, and longitudinal movement, ensuring track stability, safety, and longevity by absorbing dynamic forces and vibrations from trains. They provide essential clamping force (toe load) and flexibility, essential for high-speed rail where rigid fastenings fail.
Key Functions:
- Secure Rail to Sleeper: They create a strong, reliable connection between the rail and the concrete or wooden sleeper.
- Maintain Gauge & Alignment: ERCs keep the rails at a consistent distance (gauge) and prevent them from shifting sideways (lateral movement) or lifting (vertical movement).
- Absorb Dynamic Forces: Made from spring steel, they flex and absorb impacts and vibrations from moving trains, reducing wear on rails and components.

- Resist Creep: They provide resistance to longitudinal forces (creep) that try to move the rail in the direction of the train's travel.
- Enhance Safety & Longevity: By controlling rail movement and absorbing shock, they contribute to overall track stability, safety, and extend the life of the track structure.
