Hell Bound Train "depicts the devil as the train's engineer both driving his locomotive toward hell and tempting the sinner-passengers that occupy various cars on the train. The film is divided into episodes each one representing a different kind of sin or sinner and set in a corresponding car of the train" Tepperman, 233-234.
Available on DVD box set released in 2015 'Pioneers of African-American Cinema'.
