Rail Anchor
Function: A device installed on the base of the rail to prevent longitudinal movement (rail creep) caused by thermal expansion/contraction and train braking/acceleration forces.
| Feature Category | Specification & Description |
|---|---|
| General Function | To resist longitudinal rail movement ("rail creep") by gripping the base of the rail and bearing against the sleeper/ tie shoulder. |
| Key Principle | Works by "jamming" itself between the rail foot and the sleeper shoulder, creating friction and mechanical resistance to movement. |
| Primary Material | Forged or Cast Steel. Typically medium-carbon steel (e.g., AISI 1045, 1050) for strength and wear resistance. May be heat-treated. |
| Common Types | • Spring Type (e.g., Pandrol "Skid-Rail" Anchor): Most common modern type. Elastic "spring-steel" design. • Dog-Type/Clip-On Anchor: Hammered on, uses a mechanical grip. • Bolt-On Anchor: Used in specialized applications (e.g., guard rails). |
