Thomas the Tank Engine Wikia

The twelfth series of Thomas & Friends aired in September 2008 in the UK and from October to December 2008 in the US. It was narrated by Michael Angelis in the UK and Michael Brandon in the US. It was also the first animated in CGI, using a mixture of both CGI and live-action models.


Series 12 marked the beginning of the show's transition into CGI. HiT Entertainment was originally keen on producing more model/CGI series but the plans fell through because of low finances and budget cuts in the UK.

The characters' faces were animated through CGI with the aid of motion-capture animation. The physical models' moulded faces were replaced by white targets with triangles to fix a computer-animated face in post-production. The character's resin faces were only used in background shots or scenes where it was difficult to animate.

It was the first series to utilise CGI elements, with the vehicles' faces being animated in CGI and other characters being fully CGI animated. There are twenty episodes in this series and all were narrated by Michael Angelis in the UK and Michael Brandon in the US. Pierce Brosnan was originally meant to narrate this series in both English dubs, but ultimately Angelis and Brandon returned.

During production of this series, Toby received two new brass models due to his original plastic model being twenty-four years old at this point. Emily also had new model built as a backup model. For unknown reasons, this model did not have brake-pipe outlets. It would be used in the Knapford scene in the episode, Rosie's Funfair Special and in the episode, Excellent Emily.
