Thank you, Marco, that is a very full and interesting answer, well illustrated with excellent photos.
I remember your international ICE story and the camping railway. The swimming in the water tower I know is from a film, but I don't know which.
It's a small railway, but so what, look at the pleasure you and others get out of it.
And as for second-hand rolling stock, that's fine, all of mine is and for the same reason.
Thank you again.
And Ferrovie dello Balcomnia must mean the "iron way of the balcony" or The Balcony Railway.
