The twenty-second season (going under the name Big World! Big Adventures!) of Thomas & Friends started airing on 3 September 2018 in the UK and on 17 September 2018 in the US. It is expected to be released on Netflix, Hulu, and Amazon.


Season 22 marks the first major "reboot" of the franchise since the show switched to full CGI in the thirteenth season. The episodes keep their eleven minute-long runtime, but are now broken into seven minute-long stories, with an additional four minutes reserved for a variety of segments like sing-along karaoke songs, music videos or Thomas talking directly with the audience about lessons learned during a particular episode. Among many other changes, Edward and Henry were removed from the Steam Team to make room for Nia and Rebecca, and the narrator has been replaced with Thomas in a first person perspective, while introducing the episode plots at the beginning (however, Mark Moraghan has said that he will still work on the series).

Season 22 is set after Big World! Big Adventures!. The season is split into two halves; one half sees Thomas travelling around the world and visiting China, India and Australia, while the second half takes place back on the Island of Sodor. The season will also be released on Netflix, Amazon and Hulu in the fall of 2018.[1]

    • The first season to feature the newly updated Engine Roll Call.

    • Cyril the Fogman's first appearance in full CGI.
    • The first series to feature Learn with Thomas segments at the end of every episode.
  • This is the final season of a couple of things:
  • Although they did not appear in the main episodes and only appeared in the end segments, Donald, Douglas, Oliver, Connor, Caitlin, Timothy, Ryan, Iron 'Arry, Iron Bert, Den, Hugo, Millie, Bert, Rex, Toad, Oliver the Excavator, Max and Monty all appear in stock footage of several episodes:

  • This season introduced a new sequence used at least once in almost every episode, featuring an engine backing up to the selected rolling stock, and a closeup of their couplings being hooked followed by a closeup of their whistle being blown (horns for diesels and a bell if they have one) before the start of the main plot.
  • The mist surrounding the frame in the fantasy sequences is very similar to classic cartoon thought bubbles. Depending on who is having the fantasy, it is white for steam engines (and rolling stock) and black for diesels.
