Can Rail Elastic Clips replace Rail Pads?
No, rail elastic clips cannot replace rail pads because they perform different functions in a rail fastening system. Rail clips provide clamping force to secure the rail to the sleeper, while rail pads are designed to reduce and distribute the loads from the rail onto the sleeper, providing cushioning and electrical insulation.
Rail clips: Also known as elastic fasteners, they are typically made of spring steel and are responsible for the clamping force that holds the rail in place against the tie plate. They prevent the rail from moving horizontally or vertically.
For different applications and national standards, elastic rail clips can be classified into various types, including rail e- clip, SKL rail clips, Nabla rail clip, Deenik clip, crane rail clip, Russia rail clip as well as other standard rail clips.

Rail pads: These are placed between the steel rail and the concrete sleeper and are designed to absorb shocks, reduce wear, and distribute the load from the rail to the sleeper. They can also provide electrical insulation.
As a professional manufacture of rail fasteners, GNEE RAIL can produce various types of rail pads for different rail standards, such as UIC54, UIC60, BS80lbs, BS100lbs, etc. Moreover, we can arrange customized production of rail pads according to drawings or samples.

System components: Both are essential components of a complete fastening system and are often used together to ensure track integrity and longevity. The pad goes between the rail and the sleeper, while the clip provides the force that holds the entire assembly together.
GNEE RAIL offers different kinds of railway fasteners to meet client's requirements, such as Elastic Rail Clip and Clamp, Rail Screw Spike, Plastic Dowel, High Tensile Track Bolt with Nut, Rail Base(Tie) Plate, Rail Fish Plate, Railway Shoulder(Insert), Fish Bolt, Railroad Rubber and EVA Pad, etc. Samples and drawings provided by customer, we will manufacture qualified products accordingly.
