Hi. I searched for this problem but did not find it on the forum. In the journey on HBK, section "Doppeltes Problem", the last episode is to drive the Dosto train with the cab car from Lübeck Hbf to the yard (Lübeck Bw). There is another train on the adjacent track, which leaves after a few moments. The exit Hp signal at Lübeck Hbf however stays red and I am stuck at the platform. As such, this drive cannot be completed. Edit: contacting the signaller does not solve the problem. The message is "Abgelehnt. Auf Signalwechsel warten". (denied, wait for signal change).
You need to wait a bit longer. There's an incoming passenger train which needs to clear your track first, and it's a fair distance away.
