"I was going to pass you...until then, but you've failed."
— Mr. Simpkins talking with Wilson, Koko Pulls it Off

Mr. Simpkins is the minister of chuggers, who examines the Trainees during their passenger carriage tests. His only appearance was in Koko Pulls It Off.


Mr. Simpkins isn't the easiest man to work with as he takes things much too seriously and doesn't take a joke either (as opposed to Irving). It only takes a wise old chugger like Irving to make sure Mr. Simpkins does his job properly and behave nicely to the Trainees.



  • Mr. Simpkins once was tested to test Irving for his recycling badge.
  • His only appearance was in Koko Pulls It Off, and he never appeared in the show again.
  • His UK voice actor, Jimmy Hibbert has also wrote for a number of episodes for Season 1.
