Isobella/Behind the Scenes

Television Series
Isobella is a fictional sentinel steam lorry created by Phil Fehrle with writers Jonathan Trueman, Abi Grant and artist Robert Gauld-Galliers.

In 2002, she made her debut in the sixth series of Thomas the Tank Engine & Friends in the episode, Jack Jumps In. She later appeared in the spin-off series, Jack and the Sodor Construction Company.

Isobella has not appeared in the television series since 2006.

Live-action model
Isobella's model was custom built and painted in a matte finish with the numbers made from custom stickers.

Unlike the other pack characters, there were only two remotes built to control Isobella, one was used to control her movement, and one was used to move her eyes.

Present Day
After production of the model series wrapped in 2008, most of the models and sets would be put into storage, with some being put on display at Drayton Manor Theme Park. All other models would be logged and referenced in 2009 by HiT Entertainment, from this HiT would decide on which models were to enter storage once again, which would be given to crew members and which to be disposed off. Due to only having one model made, Isobella's model would stay under HiT and later Mattel's ownership.

Isobella's model is currently in Mattel's storage unit in Southampton England.
