Madison Depots Madison's Georgia Railroad depot is one of the oldest in the state. Built in the 1840s (or perhaps in 1857-58, suggests Wilber Caldwell), it has stood here for at least a century and a half. Parts of the building were set afire by Union troops in 1864, but the damage was repaired the following year. Across the tracks is the town's former Central of Georgia depot, built in the early 1900s (below). A city of some 3,700 population, Madison is the county seat of Morgan County. It is about 50 miles east of Atlanta.   Georgia's Railroad History & Heritage. Copyright, Steve Storey.
