What is the function of elastic rail clip?

Rail clip is a component of railway fastening systems. It is used to fix the railroad track to the underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper. One extensively used type of rail clip is an elastic rail clip made of hot-pressed spring steel. Its energy produced at elastic deformation can alleviate the vibration and shock when trains move.

What is the function of elastic rail clip?

The main function of an elastic rail clip (ERC) is to securely fasten railway rails to sleepers, preventing vertical/lateral movement and maintaining consistent track gauge for safety, while its elasticity absorbs vibrations and accommodates thermal expansion, ensuring a reliable, long-lasting connection against dynamic forces and fatigue.

Key Functions:

• Fastening: Creates a strong connection between the steel rail and the sleeper (or tie).

• Secure Positioning: Prevents the rail from moving, bending, or twisting, ensuring it stays in its proper place.

• Gauge Maintenance: Keeps the distance (gauge) between the rails consistent for safe train passage.

• Vibration Damping: The clip's inherent elasticity absorbs shock and vibration from passing trains, reducing wear and tear.

• Thermal Allowance: Allows for controlled expansion and contraction of the rails due to temperature changes.

• Resists Forces: Withstands high static, dynamic, cyclic, lateral, and torsional forces from trains.

• Fatigue Resistance: Designed to endure repeated stress cycles over its service life, with properties like bending, torsion, and corrosion resistance.

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.

How Do Rail Clips Enhance Railway Efficiency?

Rail clips play a role in enhancing the effectiveness of railway operations through supporting track stability and durability.

• Contribution to Track Longevity

Through the attachment of rails with rail clips; it aids in minimizing unnecessary movement that could result in wear and tear over an extended period. This proves beneficial in prolonging the lifespan of both the rails and the supporting structures; thereby decreasing maintenance expenses and operational downtime.

• Improvement in Train Performance

Maintained rail clips that keep the tracks stable leading to smoother rides with less vibration and noise improving passenger comfort and reducing energy consumption by enhancing train dynamics.

GNEE RAIL offer an extensive range of rail clips with optimum quality, these rail clips are designed with high precision and made up of premium grade spring steel. GNEE has been the largest and most competitive production base of rail clip in China after more than 18 years' rail clip producing experience, and have qualification to tender nationally large and medium scaled rail projects. What's more, our rail clip can be customized according to clients' requirements.
