Rail pads are elastic polyurethane mats which are interposed between steel rails and railway sleepers to protect the sleeper top from wearing and impacting.
The starting stiffness of a rail pad is designed to not be high so that their relative deformation under the spring clip toe loads is greatly substantial. In this way, it can guarantees the rail pad maintaining in close contact with the rail despite of any vertical movements of the latter. In addition, the reason why rail pads made up of rubber or plastic is to dampen the shocks of vibration of a passing train.
Railway rubber pads are typically made of high-quality rubber that is capable of withstanding harsh weather conditions and heavy loads. The most commonly used rubber for railway rubber pads is natural rubber, which is derived from the sap of rubber trees.
Synthetic rubbers such as SBR (Styrene Butadiene Rubber) and EPDM (Ethylene Propylene Diene Monomer) can also be used in the production of railway rubber pads. These synthetic rubbers provide enhanced resistance to oil, heat, and weathering, making them an excellent choice for use in railway tracks.

GNEE RAIL has developed a series of high-performance elastic rail pads. Commonly used materials include HDPE, EVA, and rubber, which effectively meet stiffness requirements for various application fields - from tram tracks to standard gauge railways and heavy-haul railways. These pads are particularly suitable for use in E-type rail fastening systems and SKL-type rail fastening systems.Contact us to get product prices.
Rail pads for SKL rail fastening systems
A rail pad in a SKL rail fastening system is a small but crucial fastener part, working together with SKL clips, screw spikes, plastic dowels, guide plates and so on.
