Has anyone had any issues with this scenario. I get all the way to Coswig, change ends to drive back and cannot get the train to move. Brake key sorted Doors sorted Speed selector sorted Force meter sorted Brakes set to release It is at this point as soon as I get to 5bar and let go it drops back to 3bar. Traction brake is stuck on. I then went back to the other end and released the brakes in the cab car, nada... still stuck. 40 mins wasted.
