I would love this Route, just like the TS1 Route, because it has a mix of everything. It has got High Speed, with the ICE 1, 2 and 4. Regional Trains with the Metronom Services, and S-Bahn Services with the BR 424 and BR 425, (although they will be taken over at the End of 2021 by Flirt 3 Sets). Also it would be a good Route to exist next to Hamburg-Lübeck.
Absolutely! This route would be too massive to develop to TSW2 right now, but DTG is trying to make tools, that would make route developing faster, so in future, this would be possible. Because this route exists in TS20xx, this route's development would be essentially a "copy and paste" from TS20xx to TSW2. Although station buildings need to be modelled again. But would be a perfect addon for TSW2.
This route has been suggested multiple times therefore I'll refer to another thread, where I've also contributed some details and thoughts about the line: https://forums.dovetailgames.com/threads/route-suggestion-hamburg-hannover.36796/#post-266186
