Is this the route you mean? This is another thing I have found on Google but I am not sure if it is correct. Some more detail in your suggestion would be very much appreciated.
A cool thing on this route is we would be able to drive along the beautiful Bodensee for a longer distance (maybe even would be able to see the ferries on it). I really like S-Bahn Vorarlberg and alpine panorama, but I hate that the Bodensee part is just so short.
Yes I mean Lake Constance belt railway from Lindau to Radolfzell, the route I Mean for the Train Sim World 4
