PS5 Br185, Shunting Scenario And Red Light, Scenary Errors

In the train prep scenario, your using a BR185 to assembly various coaches and engine together. After final assembly you leave the assembled coaches in a yard. It then says uncouple which I did, it then says return the BR185 to the yard but first it sends you to the station where there I think 5 ICE trains waiting in the station. When I get there it then tells me where to go. At this point I can't go anywhere, the signals are on red, contact dispatch/signaller and it says wait for signals to change. I waited an hour, no lights changed. When you look at the map, it's red lights everywhere, zoom out and look at the whole area and there are no trains moving so no conflict at the time.
Anybody else that has done this scenario, how long did you have to wait for the signal to turn green.
Also I had done it all upto this point with no wipers and it's rainingg heavily, the wiper control is not in the manual, I found it whilst waiting for the green signal, it's on the right hand side of the driving position and low down, I couldn't access it whilst sat down.

 

Forgot to add this bit, there are overhead line support towers which are on the track and go through the train, Dovetail please fix this.

 

Nobody else having this red signal problem?
