On November 1, 1980, Seaboard Coast Line Industries and Chessie System merged under the holding company CSX Corporation.

Finally, on August 31, 1987, the Chesapeake & Ohio (still under the Chessie System entity for corporate reasons) was merged into CSX Transportation.

[3] (The Western Railway of Alabama would remain an operating subsidiary until December 2002, when it was finally merged into CSX.

Because the merger did not occur until December, locomotives after October 1982 were to receive the Seaboard System paint scheme with the existing railroad's reporting marks applied.

[1][3] When the merger officially took effect on January 1, 1983, all former reporting marks were to be either removed or patched with SBD initials.

In June 2023, GE ES44AH unit #1982 entered service, being repaired and repainted at CSX shops in Waycross, GA with a CSX blue and yellow color scheme on the front (nose) and cab of the locomotive and throughout the rest of the locomotive, the classic grey Seaboard System scheme.
