Based on the Railway Series of children's books, "Thomas & Friends" features Thomas the Tank Engine going on adventures with his fellow locomotives on the island of Sodor. Thomas is apt to get into trouble by trying too hard to be, in his words, a "really useful engine," attempting to do things that are best left to bigger engines. Other members of the North Western Railway include Percy, James, Gordon, Henry, Toby, Edward, Duck, and all their friends on the Island of Sodor.
