Georgia Midland Railroad was established in March 2004 to operate four former Ogeechee Railway lines: (1) the 15-mile line between Roberta and Fort Valley in middle Georgia (once Southern Railway); (2) the 13-mile line between Fort Valley and Perry (once Central of Georgia); (3) the 29-mile line between Dover and Metter near Savannah (once Central of Georgia); and (4) the 21-mile line between Ardmore and Sylvania near Savannah (once Savannah & Atlanta).
Ogeechee Railway had leased these four lines from Georgia DOT, along with the 42-mile line between Midville and Vidalia. The Midville-Vidalia line was transferred to Heart of Georgia Railroad.
In 2008 Georgia Midland sold the Ardmore-Sylvania line back to the Ogeechee Railway.
Georgia Midland Railroad was owned by Atlantic Western Transportation of Americus until early 2010 when AWT sold it to Georgia Southern Railway.
