CGI opening title sequence Season 13-18


CGI opening title sequence Season 19 onwards

The CGI Series refers to the television series as it was produced from the twelfth season onwards. In 2008, HiT Entertainment announced that Thomas and Friends would be undergoing a radical change in production. The company announced its intent to relocate production of the series from the United Kingdom to Canada. With this change, HIT announced that future Thomas productions would be animated with Computer-Generated Imagery.


HiT Entertainment's Senior Vice President of Production and Programming, Christopher Skala, stated that the change, aside from budgetary reasons, was intended to convey more emotion and flexibility through the stories. Skala claimed that, of his focus group, even those who felt that Thomas, as an institution, should not be changed in this way ultimately responded positively to the demonstration of the new animation techniques.

Twelfth season

As part of a transitional period, the twelfth season would see computer-animated faces and characters superimposed over the live-action environment of earlier seasons. Characters could now display a variety of new expressions and their mouths would move in sync with the storyteller's voice when they are talking, whilst their thinking is evident when their mouths aren't moving in sync! People, animals, and certain other characters became wholly CGI elements.

This change was made possible by motion-capture animation. When a character's face needed to move, the moulded faces of earlier seasons would be replaced by a target, to which the computer could attach a face in post-production. The animation for this and future seasons would be provided by Nitrogen Studios, based in Canada.

This season saw the return of old favourites such as Duck, Oliver, Toad and Stepney.

Characters Introduced:

  • Hank - a strong American engine.
  • Flora - a yellow steam tram.
  • Colin - a green wharf-side crane.


  • The first season to have only twenty episodes.
