Two main functions of railway pads

Aug 28, 2025 Leave a message

A rail pad, also named rail rubber plate, is usually used between tie plates and sleepers or between rails and tie plate. The rail pad is made of elastic polyurethane mat and usually used on concrete sleepers. The rail pad can protect the concrete sleeper from abrasion and impaction, and it can also decrease the vibration from the passing train.

 

It is believed that rail pad functions in two ways: diminish shock and distribute load.
