Hello! I have a problem with the AFB in the BR 101 Expert. I don’t get the loco running with AFB. Whenever I activate it, apply power and release breaks, first the pressure in the break cylinders got to 0, but goes up to 4-5 bars immediately after it. This happens during ride and when the train stands still. The loco applies power, but the train immediately breaks to zero speed. I didn’t find a solution in the web for this. Does anybody have a hint for me?
AFB applies the brakes again if you don’t get going quick enough. If you’re starting with AFB, you essentially need to floor it with full throttle. Once you start rolling, you can then cut back the throttle again to the usual force you’d use. You can see this nicely here from 1:01 on: Notice how the driver floors it to get over AFB protection and after the cut, the throttle has been brought back to only use 25kN per traction motor.
