What is ERC in railways

Oct 30, 2025 Leave a message

Elastic Rail Clip (ERC) is used for fastening the rails with PSC Sleepers. The Elastic Rail Clips used in Indian Railway are mostly Pandrol Type, and therefore many times they are referred as "Pandrol Clips" also.

 

rail fastening

 

Function: To fasten the railway track to the sleepers.


How it works: The clip exerts a continuous downward force, called the "toe load," on the rail.


Materials: It is typically made from forged spring steel, such as grade 55Si7.

Design: ERCs are designed to withstand dynamic forces and vibrations from trains, making them suitable for modern, high-speed tracks.


Components: An ERC assembly often includes the clip, a rubber pad, and a liner.

Maintenance: The toe load is a critical parameter that must be checked periodically to ensure the fastening is working correctly.
