How inspirational and trams a good subject as well. You are 8 years older than me so guess I ought to put my thinking cap on.

I also went to The Tram Museum you mention in Crich , although many years ago.

Whereas there as many books about trains prior to the war not many about trams or even the good old trolley buses.
I recall my mother taking me to see a relative , in I think Wallington , from Sydenham. Part of the journey at least was by trolley bus.

Good Luck with your venture.
