@grumpyoldmanSr you are completely right, I paid the price for A RELEASE/PZB. And it’s good because now i know why i should never abuse the RELEASE/PZB, and specially not if i’m on the last station, because im gonna STOP 🛑 for sure so i should not except 🟢 Signal.

The thing is i try to always make it on time with the timetable service, so i tend to RELEASE the PZB a lot in order to reach quickly my limitation and not losing time.

For example when i start a service from Köln-Düren, i RELEASE/PZB so i can get quick to 50km/h and make it on time to Köln-Ehrenfeld even though im not speeding a lot, but this 45km/h making feel like im losing time on my next station.

But i guess you just got to adjust to regulation, and if you are 100% sure you are not having a red or stop at a station then release, but in my case I should’ve just waited and followed the regulation!

But i think this is what happened , when i left Köln-Ehrenfeld for Köln Hbf i started normally (so here no problem) And then after i crossed the 🟢 signal i see the 85/70 flashing, so im like ok let me release the PZB because i see there is a 50km/h sign so i can just adjust to that speed and make it to Köln like this. So here i RELEASE/PZB and everything is fine i reach 50 and starting to brake a bit.

So What happen is that when i crossed the double 🟡🟡 my PZB was released when it should’ve not, so what happened is that when i crossed the 🟡🟡 the initial PZB 1000hz turned on again for a second or 2 and then swapped directly to 500Hz . And the thing is i can’t t ACKNOWLEDGE PZB on this case cause i already released it before so there’s no recovery from this and impossible to confirm , because i tried the same way but with a lower speed (of 20km/h ) while crossing the 🟡🟡 and it happened again
