Linke Rheinstrecke Ruhr Not a completable service as there is a train in platform 3. Play your game. Or at least have an AI go through the route, even that would pick up the the bug. Every single route has at least 1 uncompleteable service, so it's not like you're unaware of the issue. Beyond a joke how untested your releases are.
I believe the problem here is that the cargo trains leaving from this platform at Koblenz use the wrong side track for some distance (for no obvious reason). Hence, you end up in a deadlock in front of Koblenz. When I played this service, it didn’t help that I was about 6mins ahead of time. I would assume that if you arrive late, there may be enough time for the other train to have left already. On this DLC there seem to be a very high number of very odd and buggy pathings. Behind Bingen I had to wait for 5 mins the other day, as a 628 was hauling towards me on the wrong side track. There are other examples as well. I hope that all of this gets corrected with the patch.
