Duck

Montague, affectionately known as "Duck" because of his supposed waddle, is a green pannier tank engine. Duck runs his own branch line with Oliver. He holds great pride in being Great Western and this results in him having a strong work ethic. This can, however, be a cause for friction with the other engines, when he insists that his way is the only right way to do things.

Bio
Duck knows how to hold his own and tends to stand for no nonsense from any engines that might get ideas above their station and try to order him or others about; as a result of this and his strength, most tank engines look up to him. However, although he and Thomas are friends, they occasionally have not always got on well due to the latter’s cheeky antics but the two later shared a mutual respect since the two ended up working together to help Harold and have always had a great friendship with each other.

Basis
Duck is based on a Great Western Railway (GWR) 57xx Class 0-6-0 pannier tank engine with added sand boxes. Duck's Great Western number, 5741, was that of a real 57xx, one of the first fifty 57xx Class (Nos. 5700-5749) built by the North British Locomotive Company on 31 March, 1929, and scrapped at Swindon on 31st May, 1958. However, according to Sodor: Reading Between the Lines, "...through this might not, in fact, be the number with which he was allocated when built...". 863 of these engines were built by various manufacturers over a twenty-one year period, making it the most produced class of British tank engine. Sixteen of these engines survive in preservation. However in Percy the Small Engine and The Eight Famous Engines, Duck was incorrectly illustrated as a Great Western Railway 64xx Class 0-6-0 pannier tank engine. On top of that, none of the 57xx's were autofitted to work with autocoaches.
