Continuity mistake: When Mickey hides Pluto in his suitcase, the entire handle to the suitcase breaks off and Mickey tosses away the handle. This handle reappears unbroken when Mickey takes Pluto out of the suitcase and then quickly hides him again, though it's broken again in following shots. Then at the end, when Pete tosses both suitcases off the train Mickey's suitcase has the broken handle, but when it lands on Mickey and Pluto the handle reappears unscathed once again.
Continuity mistake: There's a hole in Conductor Pete's right shoe sole which repeatedly disappears and reappears.
