Summerville Depot Summerville's former Central of Georgia depot is now the home of the Chattoooga County Historical Society as well as the terminus of a popular excursion train operated by the Tennessee Valley Railroad. Across the street from the depot, a turntable allows locomotives to easily reverse their direction. In 2006, Georgia DOT provided $100,000 in Transportation Enhancement funds to rehabilitate the building. (Photos below by Carmine Fischetti).   Georgia's Railroad History & Heritage.
