Duck the Great Western Pannier Tank Engine is a green pannier tank engine from the Great Western Railway.
He wears the number 8, and he has the letters, "GWR," painted on him in gold. Like all of the engines on the Island of Sodor, he is really useful. His best friend is Toby. He used to work for the Great Western Railway, but now, he is part of the Steam Team on the Island of Sodor, and is ready to complete any task that he is given.
