On the service R1417 there is a red signal blocking the path at Untersax Line 1. I’m on Xbox series x. I did the Chur runaround at 7:03am and then started the Chur To Arosa service straight after. I arrived at the go-via objective at Untersax Line 1 at 7:25am in game and there was a red signal blocking access to the line to continue towards Luen Castiele. There was no AI train coming down on any single line section as I checked with both the free camera as I have a keyboard and on the map as well.
