I’m doing Frankfurt - Fulda Mind the gap scenario. In the 411 After the message comes up “Hello driver we have had a call from another ice train stranded on the tracks”. This alarm won’t switch off PZB acknowledge and release buttons won’t do anything. I’ve also checked the cupboard. Sifa, PSB, LZB, are all Isolated. GNT is normal How do I turn this alarm off? Train is still moving and the brakes are not automatically applying either.
