Just drove above stated service with the dosto cab car. Couldn’t finish the service as I got stuck on an eternal red just outside of Hamburg Hbf. On the map I can see an AI train blocking my platform. He can’t leave the station as he is also stuck on a red signal.
This seems to be part of a bigger problem, known for months, apparently ignored: https://forums.dovetailgames.com/threads/a-whiter-shade-of-shame-sherman-hill.49175/#post-416743
