Diesel (AEG)/Behind the Scenes

Background Information
Diesel is a fictional standard gauge diesel locomotive created by the Rev. W. Awdry with inspiration by editor Eric Marriott.

He first appeared in the first series episode A Thomas Promise, which first aired in 2021.

Unlike the original television series, Diesel is a part of the main cast of engines in All Engines Go. Instead of being an antagonist, he is portrayed as one of Thomas' best friends and lives at Tidmouth Sheds with the other engines. He is also explicitly portrayed as a child character, and while still competitive and prone to teasing as his original counterpart, Diesel is much more sympathetic and always tries to make up for misdeeds in the reboot.

The character is voiced by Henry Harrison in the UK with a British accent, while he is voiced in the US by Shomoy James Mitchell with an American accent.

2D animated rigs
Diesel in All Engines Go uses a series of complicated 2D rigs created by Nelvana Studio. These rigs are made up of different assets, which can be stretched, squashed and posed to create the desired movements and poses. Diesel's movements are handled by an animation team, with a posing team to create specific poses as required for certain shots.

Diesel's 2D design has undergone many changes from the design used in the original series:
 * His forehead is now much larger.
 * His nose is more rounded.
 * He now has purple irises.
 * He is much smaller in size.
 * He has dark purple elements on his body, including:
 * A dark purple stripe along each side of his bonnet.
 * Dark purple wheels, valences and running board.
 * Dark purple toolboxes, which now also have grilles on the sides.
 * He lacks his outside frames and coupling rods.
 * His cab doors have been redesigned.
 * His cab windows have been removed.
 * He now has grilles on the rear of his cab where his windows used to be.
