What are the 3 materials used to make rail pads

Sep 26, 2025

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. Its defined stiffness is used to increase the elasticity of the superstructure of the ballast and reduce shock and vibration in the rail system. With such upgraded load distribution, it will lead to greater passenger comfort and less wearing onto the superstructure.
