Listen to a live scanner audio feed from Decatur, AL! See below for a map of Decatur and the surrounding areas so that you can follow the action as it unfolds! Normally rivals, the Norfolk Southern and CSX join forces in Decatur to cross the mighty Tennessee River. Although the bridge is owned by NS, it actually sees more CSX traffic per day than it does Thoroughbred traffic. Decatur is on the Memphis to Chattanooga NS route and the Nashville to Birmingham CSX route. Both CSX and NS have medium sized yards here for interchange traffic and local industry. Local industries served by rail in Decatur vary from chemical plants to pet food manufacturing, almost all of which are located along the river.
