thanks for all the advice so far.
As to being a train enthusiast, well put it this way, I spent most of my holidays on Plymouth station with my uncle, who was a shunter in the late 60's.
I used to love the steam trains and have some great Cuneo prints. I used to drag my son when he was younger to the steam museums and train companies.
So not a nut, but very interested and always have had an interest.
