Series 13

The thirteenth season of the television series aired in January and February 2010 in the UK and began airing in the US in September of 2010. From this season onwards, all footage was CGI-animated.

Michael Angelis and Michael Brandon narrated all twenty episodes, but, like Hero of the Rails, voice actors provided the voices for the characters. Mark Moraghan later re-narrated one episode specially for the Santa's Little Engine DVD in 2013.
