Stanley

Stanley is a tank engine who appears in The Great Discovery. Stanley is a big and strong tank engine that is brought to the Fat Controller's railway. Thomas is afraid that the new engine will steal his spotlight, so he tries to make Stanley look silly by playing a trick on him. The plan goes wrong, however, and when Thomas goes missing, The Fat Controller launches a search party all over Sodor. Thomas is found by Stanley, and the two become great friends. Stanley is described as "like Thomas, only larger".
