The twelfth series of Thomas & Friends began airing in September 2008. 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 he was eventually replaced by Angelis and Brandon, respectively.
Unexceptionally, 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 its low finances and budget.
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.

- Despite using CGI for the engines' faces, there are scenes that show some characters with their face castings.
- One year later in 2009, the twelfth series along with the eighth to eleventh series aired at 5.35 or 5.40 am on Sundays and Mondays until the rights from live action model animation expired in 2012.
