I just wanted to add a really great Swiss route to the list: The Gotthardbahn Alpine Classic.
It is made by the new 3rd party developer Rivet Games who now have a variety of Swiss content. Most of it is narrow gauge (Rhb) but they are getting into the normal gauge routes too, as this route suggests.

The quality is excellent and the Swiss countryside is breathtakingly beautiful. Do any of you own this route? What do you think of it?
