The New Series is a term used to refer to the seasons of Thomas and Friends produced by HiT Entertainment between 2004 and 2008. Season 8 introduced many new changes to the series: the new title sequence featured a new theme tune based on the song Engine Rollcall; the series featured newer models with different paintwork, new facial expressions and more dynamic camera work; the episodes became longer, being seven and a half minutes long; and the series, when aired on television, was often split into thirty-minute blocks with three episodes, educational puzzles and songs and the "Engine Rollcall" played at the end.
The new series was a big change from the classic series and often included recycled plots, such as Henry again requiring "special coal", and the engines appearing to possess the ability to move without a crew. The series also introduced more female characters, which the classic series was criticised for the lack thereof.

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 are not 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.
