The Augusta Southern Railroad (reporting mark AUS) was established in 1893 through a reorganization of the Augusta, Gibson and Sandersville Railroad.
The railroad acquired the Sandersville and Tennille Railroad in 1894 and then in 1897 was leased by the South Carolina and Georgia Railroad. The lease ended in 1901 at which time the Southern Railway took control.
The Georgia and Florida Railway acquired control of the Augusta Southern in about 1918, and purchased the property directly on October 31, 1919. Part of the line was abandoned in 1934, but it is still operated by the Norfolk Southern Railway north of Hephzibah.
