Railroads

Gadsden County has at least four existing railroad lines, three of which are owned by CSX. The first two CSX lines being P&A Subdivision, a line formerly owned by the Louisville and Nashville Railroad, and the other is the Tallahassee Subdivision, a former Seaboard Air Line Railroad line. These two lines meet in Chatahoochee and served Amtrak's Sunset Limited until it was truncated to New Orleans in 2005 by Hurricane Katrina. A third line is the Apalachicola Northern Railroad, a line that spans as far south as Port St. Joe. The line enters from Liberty County, then crosses SR 12 in Greensboro, runs under I-10, follows CR 268 in Hardaway, and then turns west into Chatahoochee. The fourth line is the third CSX Line, the Bainbridge Subdivision, which runs along the west side of US 27 from Leon County by way of a bridge over the Ochlockonee River to the Georgia State Line. While some spurs still exist, other lines within the county were abandoned.
