1) The light comes on at the same time as the alarm. This is incorrect: the light should illuminate 2.5 seconds before the alarm. 2) Recovery: Protoypically, if you get a Sifa penalty, all you have to do is acknowledge Sifa, zero the throttle and reset and you're good; the brakes will come off and you can resume travel. But on this loco, you get an irrecoverable Zwansbremsung.
Also: LZB Ende is completely screwed up. There is no warning alarm, no nothing; LZB just switches off, and unless you're anticipating it dumps you into a ZB (it gives you a brake warning but never applies the brakes coming into the 160)
I had the opposite problem, when there was restrictive signalling towards the end of the LZB section at Hailer-Meerholz, the Ende signal was never sent and I happily continued under LZB further on non-equipped track. Also there are some shady brake curves that seem to engage AFB braking even while way below the currently indicated curve. As in, the indicator is stepping down from 140 to 130, I am running 95 and still out of sudden I get full brake demand.
Both of these points are actually prototypical, it's just that the Vectron is a bit different from the standard German locomotive. 1. Sifa has a two tone sound warning. The low tone begins immediately when the visual warning appears (where on other locomotives it would have no sound) and then you get the high pitched tone when you are 2.5 seconds from Zwangsbremsung. 2. The Vectron requires you to reset the Zwangsbremsung by moving the train brake lever to "Fü" in a similar way as how you would override a passenger emergency application (Notbremsüberbrückung). Regarding the LZB Ende bug, that is not a locomotive bug but down to the route. It has been fixed in the beta builds so hopefully (can't see why not, but I have to cover my back lol) it will be fixed in the upcoming patch. Funnily enough this bug caused a lot of issues on the BR101 Expert since it now has LZB Transmission failure as a possible fault. When LZB dropped out unexpectedly after Hanau it triggered LZB transmission failure (as it should)... every time. That's my screw up. I incorporated some of the core updates we implemented to LZB for the BR 101 Expert on the Flixtrain Vectron. Namely that the brake curves change based on BRH. For the Flixtrain Vectron you can't input the whole ZD (train data) set, but it uses a simplified (but more realistic than previous) logic where the curves will change based on PZB Mode. In PZB O the deceleration rate is what it would be for BRH 180 (~ BrH 200) which yields about 0.5 m/s^2 on flat track. Unfortunately I forgot to update the AFB to change the expected deceleration rate under LZB based on the LZB brake curve so it thinks it's still in "freight mode" and starts braking way too early. Note, that if I had not implemented this logic it would still have been unrealistic (just less noticeable due to no AFB-LZB mismatch) since the deceleration rate for both AFB and LZB would have been about 0.3 m/s^2 (~ BRH 080/070) which is nonsense of course for a passenger train. I have fixed the bug in the editor (not yet submitted since I need to test it a bit more) and sadly it will not be in the upcoming patch, but the patch after.
It's the spring loaded position furthest away from the drivers seat, "behind" the Running position of the train brake lever. Iirc the label is "Quick Release" (or just "Release") in English.
Are those AFB brake curve fixes only for the Vectron? as the BR 146 seems to have problems too. Can't wait to drive the expert 101 in frankfurt-fulda btw!
No. That must be something different. The architecture of the AFB used on the Vectrons (all of them) I made from the ground up while doing Simugraph for the Railpool Vectron back in 2023. I have never worked on the 146 (I did some very very tiny tweaks to the 185 for KWG but nothing with AFB) EDIT: However the 146 does suffer from LZB cutting out without LZB Ende since it is driving with cab 2 from the front and there is a bug in the core LZB logic that makes LZB Ende only count in the direction of the "front" of the loco. It's the same issue I mentioned above that happened to the BR101 Expert that caused LZB transmission failure to trigger. That should be fixed in the upcoming patch next week.
