"End of the Line" is the last track from the Traveling Wilburys' first album, "Volume 1", released in 1989.
 Its riding-on-the-rails rhythm suggests its theme and the on-the-move nature of the group.
 It features all the Wilburys (except Bob Dylan who was on tour at the time) as lead singers; George Harrison, Jeff Lynne, and Roy Orbison sing the choruses in turn, while Tom Petty sings the verses.
 The song then expands into a "freight train" rhythm to underscore its theme.
