TSW GWR brakes not working on return trip of christmas closures

[Anthologee]

TSW GWR brakes not working on return trip of christmas closures, starting right before you reach the station on the return trip.
Also, when you are at the station before changing direction the aspect shows a red signal, not sure if a bug or if i am meant to use tab and ask to pass.
Asking to pass did work.
First time doing the scenario, will try again later to see if the issue repeats.
