So how did the conversation go then?
"Let's build a National Tramways Museum."
"Good idea. Where shall we build it?"
"Well, it's a National Museum, so it needs to be easy to get to, and it's about trams, which are essentially urban."
"How about a disused quarry in a tiny village halfway up the side of a remote Derbyshire Dale?"
"Sounds ideal. Go for it!"
Seriously, although the good folks at the Tramway Museum have gone to tremendous lengths: building a cobbled street, and importing the original facades of various historic buildings, the illusion is shattered every time you look outside the site.
The line is a little on the short side, but the trams seem to be enjoying themselves pottering around their retirement home in countryside. And they are lovely.
Check the Crich Tramway Village's website for opening times etc.
