The Fast Mail was a Southern Railway mail and express train that operated between Washington, D.C. and New Orleans, Louisiana. The southbound Fast Mail carried the train number of 97, and was later known by the nickname of "Old 97". One such trip made by the train, on September 27, 1903, derailed at Stillhouse Trestle in Danville, Virginia, and was later known as the "Wreck of the Old 97", which the service was most well known for.
