TerryC:
The "Field Guide" is correct, as the Seaboard System did not become an operating entity until December 29, 1982, and was created through the merger of the SCL and L&N.
The use of "Seaboard" relative to the Seaboard Air Line, Seaboard Coast Line and the Seaboard System has caused a lot of confusion and misunderstanding, especially since their creations occurred within a rather short period of time. They were a sequence of individual organizations that were separate corporate entities. The sequence continued with the merger of the Seaboard System and the Chessie System into the CSX Transportation Company, which continues as of the present time.
To add to the confusion was the use of the marketing gimmick of "The Family Lines" in terms of logo, paint scheme and marketing. However, "The Family Lines" did not exist as a separate organizational and legal entity for the purpose of acquiring and operating the assets of the SCL or the L&N. Instead, it could be described as a marketing concept to underscore the close working relationships between the various individual railroads that were included within "The Family Lines" umbrella, and how these close operating relationships could offer significant economic benefits to customers.
