When doing a timetable service and entering Redditch station where the train terminates, the AWS system will force the train to stop when going over the grids even if at a speed of 15 mph just before being able to reach the stop marker.
Has happened to me before at Redditch. I then tried going less than 10 mph over the grids and then everything was ok
Yep this worked for me as well. Maybe it is intended, although if that's the case it should be mentioned in the tutorials.
