It would be nice to have the ICE T on Riesa-Dresden it would be the first tilting train in the game and the right ICE for the route View attachment 54608
The ICE-T would be great. I've also included it in my Riesa - Leipzig suggestion, and it's diesel brother, the ICE-TD in my Nürnberg - Bayreuth suggestion.
I think the 411 also runs on Hamburg-Lübeck, so it could add a layer there. Also which one would you prefer, the 411 or the 415?
I believe the one that used to be on Hamburg-Lübeck is the BR 605 (ICE-TD), the diesel version. Not entirely sure the 411 didn't run on Hamburg-Lübeck though.
I just went by this page: https://www.vagonweb.cz/razeni/vlak.php?zeme=DB&kategorie=ICE&cislo=1581&nazev=&rok=2021 The 605 was definitely in use, but only for the services to Copenhagen IIRC. There are a few services that terminate in Lübeck, and they use electric ICEs (and a few of them should be ICE Ts).
One of those became a DB Netze infrastructure test lab therefore be added onto Riesa-Dresden SKA as a playable engineering test train if you want the route to be more realistic. Owners of Riesa-Dresden DB BR411 ICE-T can also have those on Main Spessart Bahn Aschaffenburg-Gemünden for ICE 91 service HRR Dortmund Bochum Essen Duisburg to Wien Hbf via Linz & Passau. Also HMA
