Hello I am getting the hang of the PZB system and wanted to try the S5 Friedrichsdorf - Frankfurt Süd scenario. However, there are two spots on the track, where I am unsure why the PZB system applies the emergency stop. I recorded the whole playthrough on youtube, here are the two spots i can't figure out what I did wrong. If I havent missed any rules for PZB acknowledgement, it seems to me, that the 1000mHz starts and instantly applies the breaks. Could this be a bug where the 1000mHz is detected, but not displayed? Only if I didnt acknowledge it (because i can't see it) after ~2 seconds? @ ingame-timer 7:17:38 As far as i know, I dont have to acknowledge a fully green signal? Or is there a special case when it is a signal with upcoming speed limit? Also note, how PZB goes into "expect stop" mode after resuming the emergency stop. @ ingame-timer 7:36:34 I notice that the train went above the speed limit, but I seem to be able to reduce the speed right before another mysterious emergency break is initiated. Again, I notice a sign for an upcoming speed limit which I didnt acknowledge, this time without any signals. What mistakes did I do? Or is this a bug? Any insight would be appreciated.
