Trivia[]

  • This is the first season for a few things
    • This is the first season to use the Redboard Pre-viz storyboard system.
    • This is the first season to not feature Morgan Overton and Charlie George in the UK dub due to them hitting puberty. Edward Sharpe and Toby Baddeley took over the roles of Wilson and Brewster, respectively while Imogen Bailey still retains her role as Koko.
    • This is the first season to have double length specials.
    • This is the first season in the UK dub where the episode titles are read aloud.
  • Starting from this season, episode titles are now read out and the episode title background is the same for every episode.
  • In this season some of the chuggers like Dunbar, Hodge, Emery, Zack, Tyne and Fletch now have roundhouses. Zack, Tyne and Fletch underneath Harrison, Chatsworth and Olwin. Dunbar with Jackman and Decka, Hodge next to Mtambo and Emery next to Skylar. Hanzo, Cormac, Asher, Payce and Calley have single sheds.
  • $10 million USD was invested into this season.
  • In the UK dub, Vee can be heard saying "Chatsworth and Dunbar to The Rolling Stock Yard, please!" in the background in various episodes of this season, despite the fact that the rolling stock yard was removed in this season to make way for the Working Wheels Yard.
  • There was going to be two other specials featured in this series: High Speed Action and Rescue and Repair: The New Chug Patroller.
    • High Speed Action was going to continue the Advance Training specials by having one about Koko and Speed Fleet.
      • It's unknown for now, but as these specials contained two episodes combined, the possible episodes that might have been included are Stop Koko Stop! and Runaway Koko.
    • For Rescue and Repair, there is no information on it either, though the new Chug Patorller was likely Asher.
