Old Seaboard Line

Lake Worth near LW High

This is a photo taken in 1959 of the old Seaboard Air Line (now CSX) where Tri-Rail runs. The Seaboard line existed from 1900 to 1967 when it merged with its rival, the Atlantic Coast Line RR.

The line was originally single track with passing sidings, which caused delays and reduced flexibility in scheduling. This line contributed greatly to the expansion of Florida and development of the southeastern part of the U.S.
