I’m new to this route having only bought it a couple of days ago. Does the BR 422 operate express services with limited or very limited stops and if so, is there an easy way to identify them? If anyone has a list that would be awesome!
There are lots of one-stop services between Wuppertal (Hbf) and Wuppertal-Steinbeck, and these two stations are only 727 m apart. These are services of the S-Bahn line S9. I recently found out that the westbound trains on this line give the player impossible objectives. See my thread here. If you exclude the S-Bahn line S8, which runs the full route and probably won't have any express services, there are only few other services left. I'd try those.
