The Georgia Southern and Florida Railway (reporting mark GSF), also known as the Suwanee River Route from its crossing of the Suwanee River, was founded in 1885 as the Georgia Southern and Florida Railroad and began operations between Macon, GA and Valdosta, GA in 1889, extending to Palatka, FL in 1890. The railroad went bankrupt by 1891, was reorganized as the Georgia Southern and Florida Railway in 1895, and was controlled by the Southern Railway.
