    Greetings. Please tell me, this may be the reason that the PZB indicators do not work. this is not a failure, but a bug. I tried resetting the simulation, errors, loading on different routes - it doesn't help. The security system still works on the magnets, but the indicators are not lit.

    the ZS aus light is on, could be that? try holding the MCB closed for a bit, might be lack of power

    I made this screenshot at a training ground with a single locomotive. On routes with a full train power supply, the train operates normally and the ZD indicator is turned off.

    From this picture its impossible to say whats wrong. If I spawn a single loco and set up PZB correctly it looks like this for me:

    I agree. Previously, I could just enter ZD 9 18 2 22 in the panel, and this was enough to make PZB work fine, in Obere Zugart (85) mode. But I missed the moment when something happened and now I'm trying to figure it out.

    Can you actually drive like this? It looks to me like you have not selected a direction...

    EDIT: just noticed that you are actually moving in the picture, so just forget this question...

    My screenshot shows the moment when PZB Zwangsbremsung was triggered, but as you can see, there is nothing on the indicators..

    Does this happen every time you spawn an expert 101 and try to set it up?

    After restarting the simulator, the indicators started working. I don't have any idea what it depends on yet, but if I see any pattern, I will definitely write here.

    If I go to the FTF route, in Free Play mode, and take control of a train, for example IC1279 (Expert), Fulda to Frankfurt, then PZB is not activated properly, it looks as if reverse reverse is enabled - the 1000 Hz magnet is flashing. But if I initially download this service and appear in the cab, everything works normally, and when entering ZD data, LZB (in Fulda)is immediately activated

    This is because if you spawn on foot the train is AI controlled and on the BR101 Expert the AI controlled trains run in what is essentially non-Expert mode. I just spawned on foot at Fulda 11:45 and then waited for the IC 1279 service to start at 11:46 and then took control over it. The train was in non-Expert mode so I had to go back into the machine room and enable LZB/PZB and Sifa and then everything was working correctly.

    It sounds from what you are describing that you didn't perform these steps correctly. To enable LZB and PZB you first close the LZB/PZB MCB, then open the LZB/PZB Cut-Off valve. For Sifa you move the toggle switch for the Sifa isolation switch to "Normal" and open the Sifa Cut-Off valve. It is important that you do these two steps for either system you want to enable. The circuit breakers only turn on the electrics of the system, but without opening the Cut-Off valves the safety system will not be able to enforce a penalty brake application (since the valve is closed) so it will run in an inhibited mode and for PZB/LZB this is indicated by the flashing 1000 Hz. This is all prototypical and expected.

    Lastly, if you do it this way you will need to set the train data on the ZDE panel since the memory of it will have been wiped and it then starts in "Grunddaten" when you close the LZB/PZB MCB.

    In hindsight this is not ideal (that spawning on foot forces trains to non-Expert mode) but during development it was the solution I found to prevent some nasty issues with faults occuring on AI trains or Safety systems triggering for AI drivers (mostly a sound issue since AI trains do not use Simugraph). I have found better solutions to this now and hopefully this should be more convenient in future Expert DLCs, and I may be able to patch the 101 Expert as well, but I can't promise that.

    This is a bug that was fixed a while ago but unfortunately just a few days after the previous patch was finalized. So it’s the oldest fix in the upcoming patch and as such have been in waiting for some time.

    You can see it described under bug number 80 on page 2.

    I can only get ZDS to work in free room when I spawn a formation with 2 101 coupled together not when I spawn them individually then couple them
