Last patch notes reads: I have just tried and the service still gets blocked in Feldkirch by Eurosprinter leaded passenger train. As the DB182 doesn't work with the IC coaches, the AI is unabled to open/close the doors and just get stuck there. (no mods installed). Workaround: For those people reading this in the comming years (given DTG history of fixing stuff), you can run up to the stuck train (black locos, with IC coaches), open any door by hand, wait 60seconds, and then close the doors once again. This will complete the passenger loading instruction for the AI, and train will be on its way.
Confirmed. You could also just click it on the map and remove it, to keep your timings. It's already sitting there 20 minutes before you reach Feldkirch.
