A rail pad, also called rail rubber plate, is designed between the rail tie plate and foot of the rail, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting.
The three most commonly used materials for railway pads are: EVA/HDPE/Rubber. Below is a comparison of these three materials.

Why use railway pads
- The load distribution covering a larger surface area
- Reducing load concentration and usage fatigue stress
- Even contact area between the rail and supporting components
- Reducing noise and structural vibrations
- Sealing function between the top support and rail bottom
- Reducing rail wearing and relevant supporting components
2 Typesw of Railway Pad
Studded rail pad
The studded design together with its natural or synthetic elastomer material leads to high resilience and abrasion resistance. They can also provide excellent impact attenuation, noise suppression, extended track, and ballast life.
Grooved rail pad
There are grooves on the upper surface of the rubber pad, which can ensure that the bottom of the rail is always in close contact with the rubber pad, reducing the wear of the rubber pad.
