    In scenario designer, when I try to drive the br 185, the BC brake stays at 3.4 pressure and I can only get it to 0 when I use the release brake on the dashboard. But after doing that and release the "release brake" lever, the pressure goes up to 3.3 again. I tried almost anything, but nothing works so far. Can someone help me?

    Have you turned on AFB?

    AFB was turned off (also tried it with AFB set to 40 km/h)

    Had this problem tonight with the BR 185.5. I had SIFA, PZB and AFB all on. The problem occurred as I was pulling into Riesa about to finish a freight service, when I accidentally tripped PZB and was forced to stop early. After stopping I turned AFB off, released the brakes and PZB but when I applied power the train would not move, even when power was maxed out. I tried everything from lowering and raising the pantograph, opening and closing the Main Circuit Breaker and even performing a break test; to release any potential air pressure left over by the PZB stop. I did finally notice, that the brake capsule was at 3.5 pressure, so I knew some breaking was still applied somehow so I double checked all the brake settings to make sure they were all set to release, and they all were; even the parking brake.. Totally clueless of what to do I turned AFB back on for the heck of it and after about a minute, the remaining brake pressure released; and I was able to move the train again.

    Same problem four years later. Bug I guess, never fixed.

    Just ran into this problem as well when I wanted to disable AFB. Reloading from a save point isn't even enough to reset the train's state (but does cause other bugs like LZB and PZB being reset.) Can't see any way to get around this.
    Edit: I think I just found a workaround for this issue. At this point, I've already reloaded the checkpoint, toggled PZB/LZB breakers, turned AFB on/off several times, moved the AFB speed handle to 0 and 140, throttle from 0 to on, brake levers emergency to release, reverse in forward, neutral, off and out, and toggled all three PZB/LZB buttons. What I tried just now was putting the reverser in reverse.This immediately released the brakes, allowing me full control over the train again. Back in forward, and same thing. What's also interesting now is that when I've come to a complete stop, it automatically applies 4 bar of braking pressure as long as the throttle remains off. Pretty neat.
    Edit 2: Looks like I hadn't completely gotten it, same problem returned during the same trip. Here's what I do now for a full reset:
    • Reset LZB and PZB breakers (especially is reloading from a checkpoint)
    • Make sure throttle is set to 0
    • Set AFB selector to > 0
    • Toggle AFB switch On then Off
    Brakes should now release. You can set the AFB selector back to 0 and apply throttle. After a few seconds, an alarm will turn off and the electric motors will engage.
