Commonly known as a Pandrol Clip, the ERC is a spring-steel fastening that exerts a specific “toe load” to hold the rail to the sleeper. This constant clamping force is essential for resisting rail creep and maintaining gauge. Their elastic property allows them to absorb high-frequency vibrations, and they are color-coded to identify specific diameters and load capacities. Drawing Number:-T- 5919 MK-V
