    Guys,

    Can some of you give a quick explanation or point me to an online resource that explains the proper way to use AFB & LZB above the training scenario given for KWG?

    What I'm basically asking is what is the proper procedure for slowing down & stopping at Fulda without disturbing the LZB so it can re-engage after I leave that station?

    Switch off AFB as you approach the station and drive manually. LZB will still give you a braking curve, but you shepherd the brakes yourself. Thus when you are ready to start again, you just have to re-engage AFB, release brakes, add power and you're off.

    EDIT: as I mentioned later, "switch off AFB" is unnecessary and too much work. Just apply brakes; this disengages the throttle so AFB is sidelined.

    Depends what vehicle you're driving. On the BR101 you don't need to disable AFB since using any indirect or electric brake will deactivate it temporarily (until you release all brakes). On the ICE1 I don't think this feature is implemented but you should still be able to keep AFB enabled, unless the scenario stop point is behind the LZB stop point. On the KWG BR185 I'd suggest disabling AFB like solicitr mentioned.

    I don't think that is prototypical. I.e. in the ICE 1 the AFB switch is on the back panel, and I really doubt that a normal procedure would require the driver to leave his seat and manipulate the rear panel, while approaching a station.

    But the question also is, how much of an issue is it IRL. i.e. the stop markers for freight are (once again) right next to the signal, far beyond where LZB would like to stop. IRL you it would be sufficient to stop futher away from the signal, as long, as your are fully within the sidding and have good visibility on the signal.

    Certainly it's true on any German train that applying brake will cut out the throttle, so AFB can't accelerate the train whether it's engaged or not.

    That's correct. Not sure if you were replying to me, but what I was describing is the AFB: Fahschalterquittierung which is basically a "AFB sleep mode" that engages if you make and brake (indirect or electric) applications. Ofc very few locomotives simulates this mode in TSW3. Maybe only the BR101 and (haven't tried it but someone mentioned this in another thread) the ICE3.

    Sorry for the delay in getting back to you guys - it's only the ICE3 & 101 I use for the long runs on KWG. Thanks for the instructions!
