The twelfth series of Thomas & Friends aired in September 2008. 


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.

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.

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.
