I remember that Cadbury had chocolate machines at most stations, though
they seem to have removed them about 10 years ago. Why was that?

Removed longer ago than that, I think.

Even when they worked, I suspect they probably vended more chocolate
bars to people with the necessary size of washers, rather than UK
coinage.
