Workaround is to wait for the service to arrive in free roam. It doesn't let you drive from this station otherwise.
I had no luck when trying to do them from timetable mode. This definitely wasn't an issue in TSW2020.
Can also confirm that I have this issue. I really don't understand how DTG can let this thing slip through QA. One of the basic functions of a train is the ability to move. This can't even achieve that.
Rapid Transit and Main Spessart Bahn have got updates today on my system. Hopefully this issue is fixed.
Yeah, I can now depart Dessau Hbf from timetable mode. The pantograph is raised and not stuck anymore.
