Seaboard Air Line Railroad

The Seaboard Air Line Railroad was one of the major freight and passenger railroads in the southeast U.S. until 1967, and is now part of CSX. Lines formerly operated by it or a subsidiary should be tagged old_railway_operator=SAL in addition to railway=rail (if still in use) or railway=abandoned.

See Wikipedia:WikiProject Trains/ICC valuations/Seaboard Air Line Railway for a chronology (which may have some errors) of lines constructed by the SAL and predecessors, compiled by the Interstate Commerce Commission in 1918.

The Seaboard Air Line's main line ran from Richmond, Virginia to Tampa, Florida with numerous branch lines and spurs. With some exceptions, mileposts on the branch lines usually continued from the previous line so they nearly always indicated the distance to Richmond, Virginia. Early on, the Seaboard Air Line adopoted the method of naming their lines as "Subdivisions", a practice that is still in use by successor CSX. A letter prefix was assigned to the branch lines to indicate the line.

In 1967, the Seaboard Air Line merged with its rival, the Atlantic Coast Line Railroad. The combined company became the Seaboard Coast Line Railroad. After the merger, the former Seaboard Air Line main line became known as the "S Line" and "S" was added as a prefix to its mileposts. Branch lines also had "S" added to the beginning of its existing letter prefix (example: "A" became "SA"). The post-merger milepost numbers and prefixes are still used today.

Below is a list (roughly complete) of ex-SAL lines, with mapping status.
