    I have tried this multiple times, I tried using acknowledge but the brakes are applied, I pressed acknowledge multiple times passing but the brakes are applied, I tried override but again the brakes are applied all leads to brakes being applied. How am I supposed to acknowledge this as it is not reacting the same as TSW?

    Signal is 26A north of Koebler Wald, unit is 420530.

    Which keyboard buttons are you pressing?

    You don't acknowledge the clear but the warning. (Some would say, acknowledge everything.)
    Override lets you pass the danger (red, 2000Hz) magnets (up to 25kph), not the warning (yellow, 1000Hz) ones.
    There is also a breaking curve after acknowledging, you shall not accelerate above 85 while the warning is on.
    You might also come across an active 500Hz magnet. If you cleared the warning, it will trigger emergency, because you are clearly dangerous. Except, of course, faulty signals, but anyway. You also have to be at 65kph or less while doing so, and slow to 45.

    I highly doubt it's simulated but sometimes in real life Pzb just doesn't recognize the acknowledge.
    In some videos I heard some smashing, more smashing, and then a long beep and some cursing.

    I'm sure you know that you acknowledge after passing the signal. I suppose in TSC it's the front of the loco, but when your reader passes the box you see ahead.

    Sometimes signals and magnets are misplaced in the game. Errors happen.
    It might be a little ahead, so that you pass the physical signal but it turns on the magnet. No idea how that's programmed.

    I did acknowledge the signal with the acknowledge button and I was far under 85km/h so it shouldn't have stopped, that is why I tried it on another run as if it was a 2k but the brakes were still applied

    And what is the acknowledge button? ;) Normally it's PgDn.
    I suppose it works every other time?
    I don't have the 420 installed but it has a manual which you can check. But if it usually works it's just a route building error. You can expect it and approach very slow, eat the brakes and move on after released.

    I used PgDn, it triggered the button to the right of the other two buttons so I assume this is the PZB acknowledge

    The Manual says
    When passing a distant signal set at warning, the signal must be acknowledged with the Acknowledge key (‘Page Down’or 'NumpadEnter') within 2.5 seconds of passing or the emergency brakes will be applied.

    Not really sure, your screenshot shows brakes applied before reaching the signal. That would mean it just switched from Red To Green and you were stopped by the 500 Hz magnet at the end of the bridge.

    As we do not know which scenario you are playing, I can only tell you the PZB works correctly on that route.

    One other silly thing, you acknowledge the signal after passing it.
    So to clarify, you're showing the signal to show off its state, correct?
    Otherwise it's as Spikee says, you may have passed something before. Speed limits also tend to have 1000Hz magnets (or others, but in TSC it's usually just the limit itself).

    Some locos buzz when they detect a 1000Hz magnet, try to run one of those and it should clear things up.
    (Some locos buzz only on certain magnets, didn't deduce yet. The Dispolok 189 being one.)

    There is a 500 Hz magnet protecting the main signal you are seeing, which is why the brakes are applied in his screenshot, as it must have been active at the moment of passing it and just switched to green + Vr0 - he's following traffic. You cannot acknowledge a 500 Hz magnet. You're too fast or you've previously released yourself illegally, this happens.

    No bug -> user error. (TSW is not a good safety systems teacher)

    Just to be pedantic: Vorsignals are protected by 1000hz magnets. 500hz magnets are placed 250m before a main signal.

    Only thing i can think of is being done wrong is that you are acknowledging too early. You must not do it before the signal has passed the drivers position. And then you have a couple of seconds to do it.

    Or have you already passed a previous vorsignal with double yellow and are not following the brakecurve?

    I have stopped for the purpose to show the signal, as soon as I pass with either acknowledge being pressed repeatedly the brakes will apply, this is not a scenario but this happens every time passing this signal. The 500 was not on as the signal was just showing what the signal is showing in the screenshot.

    "this is not a scenario but this happens every time passing this signal"
    The only way to pass the Signal is in a Scenario - even if you are just in Free Roam to test something.

    So it is not possible to pass this junction in free roam? I did not SPAD but every time I pass this it acts like I have SPAD.

    Either you run with PZB On and works to Its Rules or you Turn the PZB off

    Sorry to but in and correct you, but what you are saying is not correct.

    500 hz magnets are an extra protective device placed BETWEEN distant signals and main signals. They do NOT need to be acknowledged at all. In fact often there wont even be a 500hz magnet.

    You do NOT acknowledge magnets (they wont even be visible at night or below snow). You acknowledge SIGNALS!

    And when to acknowledge is easy. When you pass ANY distant warning of a limitation below (but not including) 100km/h (including stop which is essentially 0 km/h) you must acknowledge. That goes for distant signals, trackside signs, distant signal repeaters etc. Often (but not always) these warnings will be protected by a 1000hz magnet (not 500hz!) and that is what triggers the pzb system and initiates the restricted mode and the brake curve. But you MUST acknowledge the signal, magnet or no magnet.

    The correct time to acknowledge is within 4 seconds AFTER the signal passes the driver position.

    Sigh, i do wish people would stop guessing about the pzb system. I partly blame all kinds of halfbaked youtube videos made by TS players.

    I acknowledged the signal as normal with the PZB acknowledge as I passed (usually pressed multiple times) but the brakes were applied as if it was a 2000Hz despite being a green over double yellow signal. I tried again but treated it as a red/white with authority to pass (DOPSAD) with the override held but the brakes were applied again. I can't figure why the PZB is acting this way at this signal, it works fine for all others.

    Only two possibles. You acknowledge too early. You have to wait untill you’ve passed. Do not press while passing. PZB needs the following sequence. Activation from the trackside magnet - acknowledgement. The other way around should not work.
    OR it’s simply a route building error. Happens, and it’s very annoying.

    I acknowledged as I do with other signals and on one occasion tried pressing multiple times so the system should have not tripped.

    I get what you mean and I am not claiming to be trained on any German signalling systems and I get the videos I have seen on PZB contain false information. But how do I get accurate information on this as I don't have access to private training documentation? I explained what I did and how I thought the system should have reacted but other than that being wrong, I have never been trained what I am supposed to do. I can't record what I am doing wrong as all the decent capture software I used to use now use a different installation method that is more OS universal but I can't start script to get git depository files to install so I can't use any of the non-dodgy ones that don't install then demand money to unlock the ability to save and camera on screen seems to upset Youtube in the processing stage of upload.

    As DB and Siemens probably aren't going to permit discussion of more detailed information on PZB, I have to go off what we have got publicly which does seem rather generous in comparison to the limits of the allowed discussion on EMD diesel technology. But with the uncontrolled data I do have access to I am still stuck with this happening every time I drive the route, I just keep getting stopped at that one signal and unable to complete the journey.

    This goes for all routes except DTG.older than Dresden Riesa:

    If a magnet behaves faulty, i simply go into the route editor and delete it. Better a missing magnet than being cutoff by false emergency braking.

    I can recommend reading through my reply to Peter a couple of times (the one where i explain when to acknowledge). The info in that post is solid. People tend to think it’s some kind of complex voodoo, when it’s actually quite simple.

    You don't need private training documentation - the system is fairly standard across most German and Austrain routes
    The problem is DTG not correctly implementing it in all locations.

    What about Tygerways, are his videos accurate? He definitely puts a lot of work into them.

    I must admit i don’t know his videos.

    But if you have a particular question, you are welcome to ask.

    I can confirm that the videos produced by Tygerways are definitely accurate. However, he himself acknowledges that his information is not all-inclusive, since some aspects of Pzb operation are not modeled in the sim.

    Well some route/loco combos have absolutely accurate pzb implenentation. So Tygerways is incorrect in that respect.

    Kim, you misunderstood my post. I did not say that Tygerways said that pzb implementation is incorrect, simply that there are aspects of pzb operations that are not in the sim, also that DTG documentation is somewhat lightweight - those aspects that are there are accurate, except for occasional errors in a route and Tygerways is probably the best video source for those needing guidance (his videos do include references to source material). If you have links to better sources I, for one, would love to have them.

    There are routes/locos that have the full pzb implementation. As in 100%

    Konstanz - Hausach is one of them.
    Karlsruhe Offenburg and Dresden Leipzig (both dtg routes are also 100 everything pzb can throw at you)
    Berlin- Leipzig.
    All RSSLO routes as well, despite them being somewhat critisized, pzb is 100 implemented on them.
