I was driving the 10:40 RB81 from Hamburg to Bad Oldesloe on the BR 146.2, when I came across a red signal at Kupfermühle. After passenger boarding was complete, the signal remained red, even though there were no other trains nearby, up to the point where it got past the time of arrival at the next station. Tried saving, quitting and rebooting the game, but it kept showing a red aspect.
