"The FFV", also known as "Engine One-Forty-Three", is a ballad in the tradition of early American train wreck songs, based on the true story of the wreck of the Chesapeake and Ohio Railway's Fast Flying Virginian (FFV) near Hinton, West Virginia on 23 October 1890. The train was on its way to Clifton Forge, Virginia, when it hit a rock slide. Early accounts record that the engineer, George Alley, remained on the train to try to slow it and save the lives of its passengers.
It was included in the Anthology of American Folk Music and was recorded by the Carter Family. It was also recorded by Doc Watson, Joan Baez, Flatt & Scruggs and others.
An account of both the incident and the song is included in Katie Letcher Lyle's book Scalded to Death by the Steam.
