Farmington The former Central of Georgia depot at Farmington is now a store (actually Frog's Pest Control, Bait Shop & Grocery). The rails have been unused for several years and their future is uncertain. Farmington is a tiny community on U.S. 129 in southern Oconee County.   Georgia's Railroad History & Heritage.
