Thomas & Friends series 13

Thomas & Friends is a children's television series about the engines and other characters working on the railways of the Island of Sodor, and is based on The Railway Series books written by the Reverend W. Awdry.

This article lists and details episodes from the thirteenth series of the show, which was first broadcast in 2010. This series was narrated by Michael Angelis for the United Kingdom audiences, while Michael Brandon narrated the episodes for the United States audiences. Mark Moraghan later re-narrated "Snow Tracks" for the Santa's Little Engine DVD.

This was Marion Edwards' first series as executive producer.

This series was released following the release of the feature-length special DVD Hero of the Rails in September 2009 and the theatrical and video releases of select episodes. This series introduced computer-generated imagery as a replacement for the show's long-standing model animation, as well as a voice cast rather than an individual actor's narration.

Production
Beginning with this series, Nitrogen Studios began providing the animation.

Director Steve Asquith had left the show after the previous series, after working on twelve series and directing five series, while Simon Spencer also stepped down as producer. Christopher Skala was joined by Marion Edwards as executive producer. Ed Welch left after The Great Discovery, while Robert Hartshorne remained. Greg Tiernan and Nicole Stinn replaced Asquith and Spencer as the director and producer.

Note: The series was filmed in 2009, but would not be aired until January 2010.
