I would like Dovetails to extend the line from Finnentrop to Siegen and this would complete the full Ruhr-Sieg Railway. Also add moving cars, station annoucments as a game update. Add the ICE Train passenger Train set as a Locomotive add on DLC for this route and the Main Spessart Bahn line DLC
I agree with you apart from one thing: on the whole Hagen-Siegen route there never drives any ICE train. It is only Regional Bahn (RB), Regional Express (RE) and freight that drives there. (notice the speed limits in some curves) But regarding the expansion, it would be very nice to have. also working train displays on the side and microphones on stations would make it better.
Why would you want an ICE3 on RSN out of all places? That's about the least fitting route possible for that train. Not only don't ICEs go there, but with top speeds barely over100 km/h most of the time, it's really not the right route to put an ICE on... at all. MSB would be the better choice (maybe with a Würzburg extension), even on RT the ICE would be more at home if we had the above-ground Leipzig Hbf. But not RSN. Really. Not at all. On the new RRO, you could realisticly put an ICE2, the older generation, but well... 20 minutes from Hagen to Wuppertal is about all you'll get.
