I would like to report a few bugs regarding the ICE 4:

When traveling downhill, the AFB (automatic train control/speed control system) maintains the target speed by using the air brakes. However, when the AFB is controlling the speed on a downhill gradient, it should primarily use the electric (regenerative/dynamic) brake. The air brakes should only be engaged if the braking force provided by the electric brake is insufficient.

Sometimes, when traveling downhill, power is being applied while the air brakes are simultaneously engaged. The train should either be accelerating or braking via the electric brake—not both at once.

Furthermore, when the AFB reduces the train's speed—even during LZB (cab signaling) operation—it initially engages the air brakes.

In general, the braking sequence should always prioritize the electric brake; the air brakes should only be added if the electric brake is not enough.

Additionally, when braking using the driver’s brake valve, the air brakes should not be applied until reaching brake notch 4.

The same applies to speed reductions initiated by the AFB: the electric brake should always be used first, with the air brakes only being introduced if the electric brake proves insufficient.

I should also note that this was implemented quite well in the ICE 1 and the ICE 3 (the version by DTG).

I hope for a fix for these issues.

Is there anyone else on the forum who is bothered by this unrealistic braking behavior?

Compared to the BR440, the in-train announcements on the BR442 are too quiet.
They sound like little more than birds chirping—essentially just background noise. Please adjust the volume.
