The Louisiana Southern Railway Company (LS) was a railroad in southern Louisiana, chartered in 1897 as successor to several short lines which had operated along the Mississippi River, including Mississippi, Terre aux Boeuf, and Lake; New Orleans and Gulf; and New Orleans and Southern, that eventually became part of the Southern Railway system. The LS Railway served the truck farms, or large-scale market gardens, of the Mississippi Delta throughout the Great Depression. In 1952, Southern bought the 15-mile line, running along the Mississippi River from New Orleans to Braithwaite.
