Whenever i set up scenario´s on München - Augsburg all of the trains starting at München end up having a red light at the junction around Olching, and needs to wait for all the trains coming from Augsburg. Even if the train just departs Augsburg a short moment before München trains reach the signal, and have stops along the way.
The same thing happens in Service mode with RB trains. I had to wait around 15-20 minutes for ICE out of Augsburg with the train passing me at the time I was supposed to be already in München Hbf. It looks like there is an issue with the dispatcher, assigning the whole line to the fast lines between Augsburg and München.
