Hi Alan
I've been following (lurking) your progress avidly and I must congratulate you on your efforts.
Like you my interest is also in the mountainous region of southern Europe but my own layout is specifically Swiss and metre gauge. Without any criticism intended I have a couple of observations.
1 I think I am correct in saying on dual tracks the Swiss use "left hand side" and the Austrians, Germans and Italians "right hand side" ...... no doubt someone more knowledgeable will correct if I'm wrong. And, relevant to that ..........
2 Having watched many "Cab rides" on You-tube I am always amazed at the number of cross overs, almost always in pairs (trailing and facing), often medium to high speed geometry as well, and perhaps more surprisingly how frequently they seem to be used. I couldn't see any on your track plan, even at stations.
Keep up the good work and do please keep posting ........ it's addictive, and I love it!
