Rail Anchor Identification & Terminology
A formed spring-steel device that grips the rail base, engaging the base edges and passing beneath the base to restrain longitudinal rail movement.
Anchors applied on opposite sides of a tie/rail location to restrain movement in both directions.
A common anchoring pattern in which box anchoring is applied at alternating ties, when allowed by the governing standard.
A denser pattern where the applicable rail is box anchored at every tie.
How to identify what you have
- Identify the rail section or at least the rail-base width the anchor fits.
- Look for manufacturer, model, size or rail-section markings.
- Compare how the anchor jaws engage both rail-base edges and how the body passes beneath the rail base; overall length alone is not enough.
- If the anchor is installed, photograph how both jaws seat against the rail base and how the anchor body wraps beneath it.
What to measure
- Rail-base width
- Anchor overall width/length if needed
- Jaw/profile opening when requested
What photos help MidStates
- Anchor alone from both sides
- Both jaws / clips
- Under-base body profile
- Markings
- Installed fit against both rail-base edges if safely available
- Rail section markings
Common identification mistakes
- Ordering only by general appearance
- Assuming one anchor fits all 115/132/136-lb rails
- Confusing anchor quantity pattern with anchor size/model
