Duck the Great Western Engine is a fictional steam engine from The Railway Series by the Rev. W. Awdry and the spin-off television series Thomas & Friends. He is a green 0-6-0 pannier tank locomotive and lives and works on the Island of Sodor. Duck had originally worked at Paddington station as a Station pilot. Duck is not actually his real name. When he first arrived, he explained that his real name is Montague, but he was usually called Duck because everyone said that he waddled. Although he claims this was not true, he prefers Duck to Montague and now that is what everyone calls him.
