Theo/Behind the Scenes

Television Series
Theo is a fictional railway traction engine created by Ian McCue and Andrew Brenner.

In 2017, Theo made his debut in the movie, "Journey Beyond Sodor".

Theo is voiced by Darren Boyd (UK/US) in the CGI version of the series on both sides of the Atlantic, respectively.

Theo appears to be based mainly on an Aveling & Porter TJ class locomotive, like Fergus, albeit with heavy modifications. Unlike a standard TJ class, Theo has a cab which may have been inspired by Aveling & Porter's Sir Vincent. He also has an experimental gear drive system on his right side, with a similar setup to that of the Coalbrookdale Locomotive. His fly wheel may also have been inspired by Aveling & Porter's No. 807.

CGI Model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. In 2016, Theo was created from scratch in CGI by Arc Productions for the 2017 movie, Journey Beyond Sodor. The model was "hand-sculpted" in Maya, a 3D animation and modelling software.
