The Nahunta Subdivision is a railroad line owned by CSX Transportation in Florida and Georgia. The line runs along CSX's A Line from Ogeechee, Georgia, to Dinsmore, Florida, for a total of 129.2 miles (207.9 km). At its north end it continues south from the Savannah Subdivision and at its south end it continues south as the Jacksonville Terminal Subdivision A-Line.^[1][2] The line is double-tracked from Folkston, Georgia south. All of Amtrak's Florida service also traverses the line.

The segment of the line from Folkston to Callahan, Florida, is sometimes informally known as the Folkston Funnel by rail enthusiasts since nearly all of CSX's traffic from the midwest and the northeast to Florida converge on that segment, which carries roughly 40–45 trains a day. The Folkston Railfan Platform was built in 2001 by the city for viewing trains.^[3]
