Monroe Railroad (1904) The Monroe was a 10-mile line from Monroe, the county seat of Walton County, to the Georgia Railroad at Social Circle. Built in 1880 as the Walton Railroad, it became the Monroe Railroad in 1904 after the breakup of the Gainesville, Jefferson & Southern Railroad. Although controlled by the Georgia Railroad, the line operated independently until it was absorbed into the parent organization in 1917. Today it operates as a branch of the Great Walton Railroad. 1907 map (66K) 1917 timetable (340K)   Georgia's Railroad History & Heritage. Copyright, Steve Storey.
