Starting this service in journey mode, the path is blocked by a red signal, caused by another train which blocks the turnaround, as the loco stands in front of the signal. This is service R1477 Chur-Arosa, starting 21:55. What is kind of strange, it only happens in journey mode, if you spawn on foot at 19:00, this train stands behind the signal (isn't blocking the path). So, you'll have an almost 3 hour waiting time in journey mode, with a service that's scheduled for 3 minutes...
Just for kicks, I waited this out for 2h56m and confirmed that the journey mode check mark is at least obtainable. Not the ideal workaround, but better than an incompletable service!
