The E-type rail clip is a key component in ensuring the anti-creep and anti-torsion performance of the track system. By closely cooperating with rail shoulders and tie plates, it forms a stable locking structure that effectively limits longitudinal creep and torsional displacement of the rail under train loads. This ensures long-term stability of track gauge accuracy, providing a fundamental guarantee for high-speed and safe train operations. It is a core fastener specifically designed for continuously welded rail systems.
The E 2055 rail clip is designed to withstand the dynamic forces and vibrations experienced by railway tracks during train operations. Its robust construction helps to reduce track maintenance requirements, minimize rail movement and noise, and enhance overall track stability and safety.
What clamping force must the e2055 rail clip achieve?
The E2055 rail clip, a variant of the Pandrol 'e' clip, is designed to achieve a significant rail seat clamping force, typically around 5,500 lbs (approx. 2,450 kgf) at a nominal deflection, though some Chinese standards list its pressure requirement at ≥9.5 kN (approx. 968 kgf) for specific material grades (60Si2MnA). The primary goal is to provide substantial vertical hold to secure the rail to the sleeper.
Key Specifications for E2055 Clips:
Nominal Rail Seat Force (Pandrol): ~5,500 lbs (2,450 kgf).
Nominal Toe Load (Pandrol): ~2,750 lbs.
Material Hardness: Typically 44-48 HRC (Rockwell Hardness) for the 60Si2MnA steel.
Deflection: Around 7/16" (approx. 11mm) at toe load.
Chinese Standard (e.g., for e2055-1): ≥9.5 kN (approx. 968 kgf).

The Important Role of Rail Clip in Railway Track
Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Through the track bending, the pressure acts on the track. To ensure the reliability and integrity of connection between steel rails and track. Rail clips provide an important guarantee for the safety of the vehicle, and in addition, the Rail elastic clips have to withstand various forces such as bending, torsion, impact, fatigue and corrosion, so GNEE RAIL is very strict on producing and performance processing of the elastic rail clips.
GNEE RAIL as the largest rail clip and clamp production base in China, which has been qualified to tender medium and large scaled railway projects. In addition, GNEE RAIL is approved elastic rail clip manufacturer by China's Railway Ministry and has been ISO9001-2008 certified. Our rail clip product is ideal for rail track assembly for advantages of easy fitment while track laying; economical maintenance; long durability and lifespan; fast replacement.
