The twenty-fourth and final series of Thomas & Friends started airing in the UK on 2nd May 2020 and was released via Netflix in the US on 1st May 2020.


Mattel greenlit a new series and several specials for Thomas & Friends that premiered in 2020 to celebrate the 75th anniversary of the franchise. Production consisted of 20 11-minute episodes as well as three 22-minute specials following the then-recent revamp of the series [1].

David Stoten was announced as the new head writer for the series, succeeding Andrew Brenner following Steam Team to the Rescue. This was the final series animated by Jam Filled Toronto, with the animation company seemingly wrapping up production on the show for the final time by 21st December 2019 [2]. Almost every episode has a copyright of 2019; however, Thomas and the Royal Engine has a copyright of 2020 for unknown reasons.

Unlike the previous two series, the twenty-fourth series does not have an even split between Sodor episodes and international episodes. Instead, there are six international episodes - one per country - while the remaining seventeen episodes are based on the Island of Sodor. Additionally, several episodes from this series lack the fantasy sequences which were present in every episode of the previous two series.

In 2020, it was revealed by Sodor Island Fansite/Forums that the series had officially concluded due to the failure of the Big World! Big Adventures! rebrand and would not be returning for a twenty-fifth series, although the franchise itself would continue on.

Later that same year, Mattel revealed that the show would be rebooted from scratch with Thomas & Friends: All Engines Go!, which uses 2D animation instead of CGI and would be animated by Nelvana from then on. All previous media is no longer considered canon to the reboot, as it was revealed that the new series is a completely separate show and franchise rather than a twenty-fifth series due to the 1984-2021 series ending.
