The Dukes

The Dukedogs were 30 Great Western locomotives of the 4-4-0 wheel arrangment "rebuilt" between 1936 and 1939, consisting of parts from two old classes of the GWR: Boilers from the "Duke" class, and frames from the "Bulldog" class, hence their nicknames - "Dukedogs". Only one survived into preservation, No. 9017 "Earl of Berkeley" at the Bluebell Railway.

The Dukedogs were the type of Great Western Engines that Duck described to Peter Sam as "Dukes" in "Very Old Engines", saying that "they were fine and stately, but they've all being scrapped". Peter Sam misunderstood that statement and thought the Duke of Sodor had being scrapped. Weather or not that Peter Sam thought that his old mentor and friend, Duke, had been scrapped is unclear, but it seems like the most obvious reason why he would get this upset over the matter.
