This road movie/historical reenactment of the history of the American railroad made in 1974 confirms what anyone who paid any attention to Johnny Cash’s music at all already knows – Johnny loved him some trains. In countless songs Johnny talked about how trains were the backbone of the country, how they brought love and loss with them when they pulled into the station, how they were able to take you away from it all to a new place. The locomotive played an important part in Johnny Cash’s music and Johnny Cash in turn played an equally important part in American music.
