Trivia

  • This episode marks the first for a couple things:
    • The first appearance of Irving.
    • One of the first episodes, along with Wilson and the Elephant to air on Playhouse Disney in the United States.
    • The first non-speaking role of Harrison.
    • The first speaking appearance of Chatsworth, barring the US and Croatian dubs.

Goofs

  • The Vee pole Koko interacts with loses her screen after the first shot of the episode.
  • When Calley backs up to the magnet car, her coupling rods do not move.
  • In this episode, Wilson, Brewster and Koko did not know how to switch points to a track. But in the previous episodes, they were capable of switching points to tracks with no problem.
  • Since Koko is electric, when she came off the rails, her wheels would not be able to move. If Koko had jumped, she should have gone straight forward.
  • In the UK and international dubs, Chatsworth's mouth does not move when he greets Wilson and Koko.
  • The captions for the BBC iPlayer release of the episode misnames Calley as "Kelly".
  • In the first scene of the episode, Irving clips through a bumper.
