This map was awesome. I finished it with three stars on my first try, but it's a challenging one that I couldn't just autopilot through. Plus, it was a lot of fun! Thanks for the map! Great work :)

Ich liebe diese Karte sehr! Vor allem das Abstellen der Züge ist sehr gut umgesetzt und erfordert gute Planung. Ich hoffe, dass noch mehr "kleine" Karte mit einem hohen Zugaufkommen von dir kommen. :)

Thanks for your feedback.
Originally I had the trains pass the border stations one minute earlier, but that lead to them parking in the next station for an additional minute. Which is not something a subway train would normally do. I guess in this case better gameplay should take precedence over realism.

I'd suggest making some stop times more lenient. Some were visually overlapping in the station timetable (well, at least one, which was 1x06 on its stop on track 2 of Kolumbusplatz), and some were sent in at the same time they needed to arrive at their next station.
I know you can send in those trains a minute early, but it's not good practice to have the game say "passing at 0:30" and "arriving at 0:30". It's messy, and I often found that if I'd missed a train entering the map by about 30 seconds, I was running the risk of it being penalized on its next stop. I would've turned on auto-accept, but then I would forget about the train entirely since I didn't set the signal ahead of it to a perpetual route because of the trains that reverse on the stub-end track that sometimes needed to use the route.

I really like that you have to park the trains yourself and have to remember to put them back in line in time.
