Thomas is a cheeky, but friendly blue Billington E2 who lives on the North Western Railway from Thomas & Friends. He was originally voiced by Ben Small, but after Ben Small's departure from Thomas & Friends, Thomas is voiced by John Hasler. He showed Peppa around Sodor in the episode Peppa and the Tank Engine. He is also Peppa's new friend. His whistle sound goes: "Peep-peep!". His best friend is Percy. Thomas is in love with a LEGO train named Traina Chug.
