My suggestion is the Lake Constance Belt Railway for the Train Sim World where super cool this is my idea from me
That is also a beautiful route, I actually went on it once, it was really with the Train that moves for Baden-Württemberg, that was beautiful, that is a very beautiful route.
Heres my opinion for this Route: Lindau Insel/Lindau Reutin - Uberlingen in 2024 35 Miles C.20 Stations Included Trains: DB BR 622 DB BR 425/426 Layers (For AI) DB BR 612 OBB 4024 (To substitute for the OBB 4748) DB BR 146 & DOSTO Service wise, its mostly trundling stopping services, though semi fasts do run through to Lindau from Fredrikshafen Stadt. DB BR 425/426 only do Lindau - Fredrikshafen on this route, which would take up to around 35-37 mins to do DB BR 622 do Fredrikshafen Stadt - Radolfzell (Albeit for this route, only drivable to Uberlingen, which is approx 40 mins)
I dont wanna sound mean or something, but youve posted SO MUCH posts of different routes where your just saying "Route X would be could." And btw. its NOT Lake Constance! Its the Bodensee. Bodenseegürtelbahn, not Constance. Still, if this Route comes, it should come with the RS1. A cute Train which could be used in many other smaller Routes. Then the IRE3 with the Br218/245 + Dostos / Br612, 218 + n waggons (Freizeitexpress), RS1 as RBXX etc.
i mean, look at the original Vectron post! (i think it was vectron, im not too sure right now) Its so detailed, so many pictures and Texts! The ICE4 post is also really detailed..
