Thomas & Friends: All Engines Go! is an upcoming reboot of the Thomas & Friends series, but in 2020, an unaired test pilot was made. No footage of it was available until February 2021 when a Cartoonito Reel accidentally showed footage of it. In the same reel, footage of a fake Wind in the Willows trailer was also shown.
Update April 2021: the storyboard has been found! https://www.youtube.com/watch?v=916Bouf7_rY
- Thomas' design looks even more different to his original design than in the final show. He also has side-rods.
- A green crane which looks a bit like Cranky can be seen loading hay into Thomas in one of the clips.
- Gordon also has his 4 bogie wheels from the original Thomas & Friends in the pilot, he also has a red running board to match Thomas' redesign.
