Despite the merger in 1980, CSX Transportation was a paper railroad (meaning no CSX painted locomotives or rolling stock) until 1986. In that year, Seaboard System changed its name to CSX Transportation. On April 30, 1987, the B&O merged into the C&O. With the Western Maryland having already merged into the C&O, this left the C&O as the sole operating railroad under the Chessie System banner. Finally, on August 31, 1987, C&O/Chessie System merged into CSX Transportation, bringing all of the major CSX railroads under one banner.
