Hi Dario,
Good to see you posting again. Sorry I did not see your post asking for help on narrow gauge railways. I don't know a lot about British Narrow Gauge, but I have had to pleasure of driving on the Ravenglass and Eskdale Railway in the English Lake District. The line is about 7 miles long and has a long history. You can read about the railway and see photos at

How is your model railway club going? Are you still using the same building to house the layout? We could do with some new photos of your club model and some more Italian Railway photos. ( Old Steam with a bit of information would be good)
