Don't feel bad about that: I spent some time researching the question in the first place.Well, I've consulted Mr W Pedia about some of these stations, and I think that I know the answer.
I'll leave it to others to have a few more guesses before I offer my theory, though, given that I've done some research.
Does your theory still work if I add Betws-y-Coed to the list?
