The Billion Dollar Hobo (1977)

Clear the tracks! It's a 100 laffs-a-minute runaway as Tim goes tramping with a locomotive and a canine keeper!

Vernon Praiseworthy is a clumsy but lovable dope who stands to inherit his uncle's fortune. The condition is that he travel the rails as a penniless hobo just as his uncle did in the dark days of the depression. That seems simple enough until he gets involved in a dog-napping plot.
