Manassas Depot The simple wooden depot at Manassas hangs on to existence long after its abandonment. The rail line through the tiny town, constructed in the 1880s by the Savannah & Western Railroad, is now used by the Georgia Central. Manassas is a town of 101 people in Tattnall County, about 50 miles west of Savannah.   Georgia's Railroad History & Heritage. Copyright, Steve Storey.
