A recreation featuring 4-4-0 #17 - the York and visiting locomotive 4-4-0 #63 - the Leviathan (Chasing backwards but not in view). The event was put together by the folks at Steam Into History about a true event also known as Andrews' Raid. "The event takes place after a military raid that occurred April 12, 1862, in northern Georgia during the American Civil War. Volunteers from the Union Army, led by civilian scout James J. Andrews, commandeered a train and took it northward toward Chattanooga, Tennessee, doing as much damage as possible to the vital Western and Atlantic Railroad (W&A) line from Atlanta to Chattanooga as they went. They were pursued by Confederate forces at first on foot, and later on a succession of locomotives." - via Wiki.
