SBD=Seaboard System. In 1980 (or maybe 82) I believe CSX Corp. officially merged the companies that comprised the Family Lines (Seaboard Coast Line, Louisville & Nashville, Clinchfield, etc.) into a new corporate structure called Seaboard System. At the time, CSX Corp. owned both Chessie System and Seaboard System, and intended to operate them seperately. However, by 1986 this policy was dropped and they were merged into one railroad company, known as CSX Transportation.
Wondering if I'll see the Western Route double-tracking finished before I retire...
