The Seaboard System Railroad, Inc. (reporting mark SBD) was a short-lived former US Class I railroad that was created after the consolidation of the Family Lines System railroads (notably the Louisville & Nashville and Seaboard Coast Line) on December 29, 1982. Under the Family Lines era, the railroads shared common ownership but used different names when conducting business. On July 1, 1986, the Seaboard System renamed itself as the CSX Transportation and absorbed the Chesapeake & Ohio Railroad on August 31, 1987 which ended the CSX Corporation's shared ownership of the Seaboard System and Chessie System railroads.
The Seaboard System's roots trace back to the Seaboard Coast Line Industries, a holding company created in 1972 that combined the SCL's subsidiary railroads into one entity. Known as the Family Lines System, this entity adopted its own logo and colors, but each railroad under the Family Lines maintained their own identities. Over time, this caused confusion among customers and in comparison to the neighboring Chessie System Railroads which had three railroads, the Family Lines had five railroads.
On November 1, 1980, the holding company CSX Corporation was created after the merger of the Seaboard Coast Line Industries and Chessie System, Inc. holding companies. This now simplified ownership of both the Chessie and Seaboard's railroads under one holding company while still keeping their identities separate. On December 29, 1982, the Seaboard Coast Line and Louisville & Nashville (under the Family Lines entity) were merged to form the Seaboard System Railroad, Inc. This was the first step under the CSX Corporation holding company to combine all railroads into one railroad.
Considered as a 'temporary railroad', the Seaboard System quickly began to merge away the smaller railroads that were owned under the Family Lines System entity as well as simplify equipment/management alongside the Chesapeake & Ohio/Baltimore & Ohio (Chessie System) railroads. This included the Georgia Railroad (1983), South Carolina Pacific Railway (April 30, 1984), Louisville, Henderson & St. Louis Railway (July 1984), Gainesville Midland (1985), Atlanta & West Point Railroad (June 1986) and the Columbia, Newberry & Laurens (June 1986).
After the Seaboard System simplified itself as one railroad, it was renamed CSX Transportation on July 1, 1986. On April 30, 1987, the Baltimore & Ohio railroad was merged away into the Chesapeake & Ohio. Finally, on August 31, 1987, the Chesapeake & Ohio (still under the Chessie System entity for corporate reasons) was merged into the CSX Transportation. All the major railroads under CSX Corporation were now one company. (The Western Railway of Alabama would remain an operating subsidiary until December 2002, when it was finally merged into CSX.)
 Equipment colors and painting
Even before the creation of the Seaboard System, locomotives began to receive a simplified paint scheme of the Family Lines. However, only the Imron grey, red and yellow were actually recycled while using a completely redesigned logo with a coupled variation font of ITC Eras Demi. The first locomotive to be applied with the new Seaboard System paint scheme was UCETA GP16 #4802 in October 1982. 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.
When the merger officially took effect on January 1, 1983, all former reporting marks were to either be removed or patched with SBD initials. Shortly before taking delivery of the L&N specified EMD SD50's, Seaboard adopted a Swis721 type font for reporting marks and numbers instead of the customized Seaboard Coast Line lettering seen on pre-1983 repaints. To simplify it's locomotive roster and meet Chessie System specifications, Seaboard introduced a numbering system that partially became meshed within the Chessie System locomotive fleet as well as removed any existing Mars Lights or Gyralights on locomotives. Any new locomotives purchased by Seaboard would be built to meet Chessie specifications; which only three: EMD SD50, EMD MP15T and GE B36-7 were actually placed.
