Shocked & Disappointed (Harry Potter Hogwarts Express)

What is a Sodor Castle?

Further to MrKirby48's response, it appears that Sodor Castle is a fictional locomotive created by a Thomas fan who calls himself Rhydyronen and is named after the castle on the island of Sodor in the same way that the GWR 'Castle' class locomotives on which he is based were named after castles in the GWR area of operations. The Hogwarts Express locomotive is a GWR 'Hall' class; there were also GWR 'Manor' and 'Grange' classes. All of them were 4-6-0 and superficially similar in appearance.

An additional bit of trivia: Rhydyronen is the name of a station on the Talyllyn Railway, it is of course Welsh, and translates to 'Ford of the Ash Tree', or more simply 'Ashford' in English.

I may be wrong, but I think that in the UK at least the Harry Potter fan-base is predominantly female; which is not to say that there aren't female or indeed 'other' Plarail enthusiasts because I know there are. I dare say it may all be different in Japan though.
