JACKSONVILLE, Fla. — Nearly 1,000 CSX Transportation Engineering employees completed the annual coal route maintenance project this week. Track maintenance teams worked their way across the Appalachian coal route which includes Kentucky, West Virginia, Tennessee, New York, North Carolina, and South Carolina. Demand for coal remains strong, and on a typical day as many as 50 trains make their way across this important corridor. During this intense maintenance operation, workers installed new rail, and more than 133,000 ties. Ties cover nearly 113 miles of main line track, plus several auxiliary tracks. Crews also re-surfaced an additional 150 miles of track,
