Interesting take on travel there, Allan. The train station is indeed in a (romanticised) London. The train, however, then departs from its make-believe and oddly-numbered London platform and then travels out of London and up to somewhere in Scotland (apparently chosen because of the potential for the seclusion needed for in-story logistics).

I appreciate that Coltrane isn't speaking in his 'normal' accent. I was facetiously picking up the point about Hagrid being an 'English' part. That's very debatable when the said part isn't even human - a (half) giant - and speaks with an accent for a place that only exists in screen-based fiction. :)

My real point was more about being hung-up as to whether an actor/actress should have a modern Scots or English accent in a fantasy animation set in 9th Century Scotland.

Like all the 'celt vs English' guff that's thrown around folk music (and international forums in general), it's all pants and very often history gets in the way of romanticism.
