This F-25 Class bulkhead flat car with Barber Roller Bearing trucks was built in the mid-1960s for Baltimore & Ohio, and later repainted into the post-merger Chessie System scheme. Chessie System was formed through the 1972 mergers of Chesapeake & Ohio, Baltimore & Ohio, and Western Maryland. It was one of the largest Class 1 railroads until 1986 when Seaboard System merged with Chessie to form CSX Transportation
