Duck

A Great Western engine who prefers, for some reason, to be called Montague. The other engines say he waddles, but he doesn't really. He's proud of being Great Western, and talks endlessly about it. But he works hard too, and makes everything run like clockwork. He has trouble remembering simple names like "Hatt" and once said that the Fat Controller's real name is "Sir Toppham Thing-A-Gummy". He once got c** all over his face by The Barber. When Diesel came to Sodor, Duck took him from behind while Gordon watched with interest.

Montague
It is unknown why Duck is called Montague. Many think that he has two sisters, one called Kylie and the other being a judge on The X Factor.
