Now, I guess few have noticed this because it only happens a couple moments during every run with BR 411 (ICE-T), but if you drive with everything turned on, during LZB sections, if you let AFB brake for you for the next speed restriction under LZB (usually I brake manually, but under LZB I let AFB do its job), which happens as you get from 200 to 160 kph (preparing for LZB exit; 1st LZB section) and later as you approach Fulda (going 160 kph and gradually slowing down to 140 and 100 kph, then stopping), this actually LOCKS your throttle as if you were braking manually (which you probably arent) - which it shouldnt, even if you lowered the AFB yourself (which in this case you arent even doing)... once the desired lower speed is reached, it should resume throttle as usual, but your throttle is locked, forcing you to go down to zero and back up This bug has persisted since the launch of Frankfurt Fulda route, I personally have reported it like two times, still no result... the good news is that BR 403 RBW which I also reported for having the same bug, seems to work as expected at Kassel Wurzburg route where there are sections where AFB brakes for you from 250 to 200 kph multiple times, and it doesnt lock throttle in doing so (which I believe it did for some time) Also, and this could be just Free roam bug, but when I was testing 411 on Kassel Wurzburg to see if this AFB/LZB bug was the train's fault or not, sometimes it would refuse to accelerate over 200 kph even if the power display showed full 100% throttle and the gradient was "only" 1.3%, which doesnt pose any problems to this train on Frankfurt Fulda...
