Thomas & Friends (previously known as Thomas the Tank Engine & 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 Rev. W. Awdry. This was Jocelyn Stevenson's last series as executive producer. Sharon Miller remained as script editor. Most episodes in this series have two titles: the original titles from the UK broadcasts are shown on top, while the American-adapted titles are shown underneath.
