What is railroad pad made of

Aug 25, 2025 Leave a message

A rail pad is inserted in between the rail and baseplate or sleeper. Rail pad is introduced to the railway fastening system because of its resilience or viscoelasticity which can be implemented in the intervention of fatigue cracking of sleepers. The dynamic stress from the wheel or rail impact from both regular and irregular movements is attenuated. There is the added advantage of reducing track maintenance and associated costs.
