Gordon the Big Engine is the No. 4 engine on the Island of Sodor. He is a blue engine who pulls the Express. As the senior member of the engine family, he is the fastest and most powerful of the Steam Team, and he knows it. Although he can be boastful sometimes, he is hard working and performs his duties to the best of his ability. He is also goodhearted and forgiving, and often uses his superior strength to help smaller engines out of trouble.
Gordon is based on a Gresley Liner A3 4-6-2 engine.
