The Federal Railroad Administration is reviewing BNSF Railway Company’s request to change a signal system at the Fort Madison movable bridge in Illinois.
- Government buyer: U.S. Department of Transportation, Federal Railroad Administration, Signal, Train Control, and Crossings Division.
- Requesting company: BNSF Railway Company.
- Requested action: Approval to remove fixed derails from interlockings on main tracks 1 and 2, between mileposts 232.6 and 231.2, ahead of the Fort Madison movable bridge on the Chillicothe Subdivision.
- Key safety rationale: BNSF states that fully operational Positive Train Control (PTC) provides the safety function previously served by the derails, making them redundant and potential failure points.
- This is a regulatory review and request for public comment, not a purchase of products or services. No OEMs, products, quantities, or part numbers are identified.

### Description
