Dec 29, 2025
What is E rail clip?
An E-railway clip (or E-clip) is a high-strength, spring-steel fastener used in railway systems to securely clamp the steel rail to sleepers (ties), providing essential elasticity, gauge maintenance, and resistance to vibration, ensuring track integrity and safety. It's a key component of a complete elastic fastening system, known for its durability and performance in various environments.

Advantages of the Pandrol e-Clip
- Safe and reliable:Despite continuous innovation across the industry, rail systems around the world still request the e-Clip fastening for their projects thanks to its ongoing reputation for safety and reliability. Since the original e-Clip design, we have maintained its iconic shape and function, with updates for the modern rail system that mean Pandrol's original rail clip is as sought-after as ever.
- Self-tensioning:Fit and forget about this high-performing rail clip. The e-Clip is designed to be self-tensioning, meaning you can rely on optimised results without the need for regular manual checks and adjustments of the torque. This unlocks more efficient rail system operations by reducing the need for maintenance checks.
- Versatile:Since its creation in the 1950s, the original e-Clip design has been adapted and added to, offering rail operators a choice of Pandrol clips to suit every application, environment and market segment. From the DRS system to the e-Clip SRS, Pandrol e-Clip can be combined with several baseplates and other elements to suit the parameters of every project.
The rail elastic clip is used for fastening the rails and the tie plate on concrete sleeper. Using the material of forged spring steel, our rail clips are produced by hot forging process. GNEE RAIL can develop and produce various kinds of rail clips such as E-type(E1609, E1809, E1817, E2007, E2009, E2055, etc), SKL tension clips (SKL1, SKL3, SKL12, SKL14, SKL75, etc), PR series, Nabla clips, D type rail clip, Fast clip, gauge lock clip, Deenik clip as well as other standard and non-standard clips can be customized by drawings or samples.
