Chartered in 1846, the 311 miles (501 km) 5 ft (1,524 mm) gauge railroad ran from Memphis, Tennessee to Stevenson, Alabama through the towns of Corinth, Mississippi and Huntsville, Alabama. The portion between Memphis and LaGrange, Tennessee was originally to be part of the LaGrange and Memphis Railroad, chartered in 1838. From Stevenson, the road was connected to Chattanooga, Tennessee via the Nashville and Chattanooga Railroad. In Alabama, the railroad followed the route of the Tuscumbia, Courtland and Decatur Railroad between Tuscumbia and Decatur, the first railroad to be built west of the Appalachian Mountains.
