In my opinion, these are beautiful routes in a beautiful country. I would really like a high speed and modern Swiss route in the world of train simulation. The train I want to fit on one of these routes is either the CFF CFF FSS ICN or the CFF CFF FFS EC 250 Giruno. They are modern and beautiful trains with good performance on the track and with great sound great. Additionally, the ICN tilt technology is something we haven't seen in Train sim World yet. You don't have to be exactly like Zurich for st. Gallen or Lucerne if it's too long for this to happen in the simulation: in Lucerne for example it's only 55/60 km, so it's relatively doable in my opinion. With beautiful scenery in a beautiful country with a modern high speed train, I think this will be a route that many people are willing to take.
