I was using the BR 112 and got a random emergency brake activation and buzzer going of despite not passing a signal or PZB/LXB/Siffa magnet. Because this happened the brakes still released but there is no power so kept rolling back and would not drive. I looked at the route instructions but there is no mention of this. What am I supposed to do to get to move again or even stop random brakes from going off on the BR112? I have already found that this is not compatible with the trailer but can't even get far driven from the locomotive end.
