After uncoupling carriages end up stuck at red signal at Garston Junction until having to crash out of scenario
I'm stuck at the same location on the PC. There is a freight that was backing up to the left of my direction of travel shortly after stopping at the signal at Garston Junction. After it backed up it stopped halfway under a signal. Possibly it is causing the issue because it did not clear the block.
I have this issue as well. Since the track ends dead the message wait for signal to change is weird. I could not complete the scenario.
