Gulf, Mobile and Northern Railroad

The Gulf Mobile and Northern Railroad was a predecessor to the Gulf Mobile and Ohio Railroad. It comprised primarily of a line from Jackson, Tennessee to Mobile, Alabama, with a branching main line from Union, Mississippi to New Orleans. It also connected from Union to Meridian, Mississippi. The GM&N ran a streamlined train, the Rebel from Jackson to Mobile with a section to New Orleans.

The GM&N Rebel was not only the first true streamliner in the South, it was one of the first lightweight streamliners anywhere along with Baltimore & Ohio's Royal Blue and Abraham Lincoln, both train sets of which would eventually be inherited by GM&N successor, the GM&O through it's acquisition of the Alton in 1946. The Rebel's were built with conventional (non-articulated) construction, allowing extra cars to be switched in and out as needed. According to Johnston and Welsh in The Art of the Streamliner, the American Car & Foundry-built train sets, styled by Otto Kuhler of B&O fame, featured coach seating and a sleeper-observation car, with six sections and a drawing-room, staffed by a train hostess.

In 1940, the GM&N merged with the Mobile and Ohio to become the Gulf Mobile and Ohio Railroad.
