    Only two things that come to mind, either you didn't hit a speed threshold in time.. or you didn't acknowledge the speed 70 km/h "7" Speed sign.

    it definetly was the 70 km/h sign. always acknowledge everything below 100 km/h!

    Ong, those speed signs terrify me now, I just acknowledge every double digit speed sign now lol

    I just realized there was a 70 sign there. I was so preoccupied breaking that I didn't even notice it until you pointed it out. That is exactly what caused the emergency braking.

    There's nothing to be terrified of. Just acknowledge every speed limit that is below 90.

    Not really. You only must acknowledge speed restrictions if you slow down from a speed over 85km/h to a speed below 85km/h, such as from 100km/h to 70km/h.

    The rules are clear on this - any speed restriction below 100km/h must be acknowledged.

    Not trying to be clever as I'm new to this so forgive me if I got this wrong. I always look at the top right where it shows the route ahead with the speed and signals, that way I get prepared to slow down in time, I'm in 'Beginner' mode so may be it doesn't show once you get more advanced I don't know.

    Thank you for the confirmation. BTW, the sentence is not entirely clear, because you must only acknowledge speed limits below 100 if you are slowing down from a speed limit above 100. You do not need to acknowledge every speed limit below 100, only when you slow down from over 100.For example, from 120 to 80.

    I seem to recall that, for reductions to speeds over 70, you don't have to acknowledge IF your current speed is already within 15 km/h of the indicated speed.

    Of course, for beginners, "acknowledge anything yellow" is a perfectly workable approach; there's no penalty for hitting the button when you don't have to!

    With the way PZB works, reductions to speeds of 80 or 90km/h only need to be acknowledged if travelling at 15km/h or more above the limit (95 and 105km/h, respectively) to avoid penalty. However, the rulebook is stricter than this and requires acknowledgement in places even where PZB strictly would not penalise (e.g., acknowledgement of repeater signals). That is where some confusion lies in this thread.

    Cheers

    That’s incorrect. If you’re doing 80km/h, a restriction to 70km/h must be acknowledged. As I said, the rules are strict but clear on this.

    As solicitr said, some confusion might arise from the use of GPAs for restrictions to 90 and 80km/h and the fact that not all signals are protected by 1000Hz magnets but that has no impact on the rules. Any speed restriction under 100km/h must be acknowledged.

    I believe I have not yet encountered such braking situations. I simply acknowledge everything below 90 and never received a penalty.

    To be clear, I was talking about speed sign restrictions, not signal restrictions. In the case of signal restrictions, I acknowledge all restrictions below 100, and for speed signs, I have never received a penalty until I failed to acknowledge a speed restriction below 90.

    Be careful if you ever drive a PZB "U" train.

    Going over 105kph will give you a lovely brake curve warning, followed by the automatic brakes slamming on 2 seconds later

    The BR193 Vectron has a complete mental breakdown if you even get close to 105kph.... Happened to me on Hamburg-Lubeck before I could even react the other night. :D

    In both my post and the official Ril speed signs are signals just like ‘actual’ signals.

    I'm even more confused now. I was just playing Salzburg Rosenheim, and there is a 100km/h speed limit beginning in Rosenheim, and an 80km/h warning sign at distance post 1.4 that comes into effect at 2.4, but neither requires acknowledgement. Can you explain why?

    There are a few things in play here. First of all, if that 80 is the one I’m thinking about, it’s a bit off an odd thing with erroneous signage for a temporary speed restriction. Not sure what DTG did there exactly.

    Second of all, I think I get now where we’re talking past each other - it’s about ‘requires acknowledging’. When I say requires, I mean according to the rules and not whether there’s an active 1000Hz magnet there. As a driver you learn it like this: “You acknowledge signals, not magnets.” What that means is that an announcement signal (or board) for e.g. 80km/h must be acknowledged according to the rules - it doesn’t matter whether it actually has a magnet or not.

    In other words, there are speed announcements under 100km/h that you can theoretically and mechanically drive past without acknowledging as they don’t have an associated 1000Hz magnet. You are breaking the rules though if you do so. According to the rules as quoted above, such speed restrictions must always be acknowledged. Whether they have a magnet is inconsequential for this. The rules are the rules.

    Why though? What safety benefit comes from redundant acknowledgements?

    If nothing else, it keeps the driver more alert and aware of their situation. Same reason Japanese train drivers physically point and call out signals.

    Or why US drivers (not modeled in TSW) are expected to radio in signal numbers as they pass them. There's no actual need for it (train location has been automatically reported since CTC started), but it keeps the crew engaged.

    Obviously there's no safety gain from hitting the acknowledge button at a signal that doesn't have a PZB magnet. It does, however, not have any negative consequences either. On the other hand, not acknowledging a signal that does have a magnet will give you a penalty brake. Given that, I think it's fairly obvious why it's better to go with the rule that leaves no room for doubt, at the "cost" of making you push a button a few times more often than would be strictly necessary.

    Also, if you see a speed limit board, this way you're just thinking about and reacting to the speed limit board, instead of getting distracted by trying to see/remember whether or not it has a magnet.

    In Japan, it's even more strict. No matter what an upcoming signal shows, the drivers are instructed to point at it and speak out the state of the signal. This is named "Pointing and Calling" (指差喚呼) and the purpose is to be 100% focused and concentrated. And combining neural processes with motorical motion helps the brain to learn.

    You're doing nothing wrong when acknowledging every german signal, especially when unsure. PZB will tell you in case you must act. The rest is... practise!
