I have not yet ran passenger services yet, but I did see this problem on Matt's last stream no due times and no green check marks to show a successful arrival.
I experienced the same problem in passenger service mode, but also when driving the DB BR 146.2. There are no times listed in the schedule and no green ticks when arriving at the station.
Was there ever any official word on this? I was late to Main Spessart Bahn, and I still see this is an issue. I'm otherwise enjoying the route, but I do miss knowing if my passenger services are on-time or not. Kind of breaks the immersion.
Havent heard any offical statement about that. I reported it as a bug after launch, others probably aswell, but no idea if it is intented for some reason or a bug.
