The update "Series of AI pathing and behaviour improvements to reduce red light issues among all routes" seems to have solved most of the problems with trains stuck midway and red lights, I did a test on the RE50, last service of the fourth chapter in N Dresden, and the train that always stuck in the vicinity of Dresden Mitte is no longer stuck , now allowed to complete the once endless service since the launch of Rush Hour. Now, a point that really needs DTG's attention is the red square on the Rapid Transit trains (BR182 and Talent 2 silver) that even with the brakes released and doors closed, it remains, preventing you from accelerating the train. I'm pretty sure the BR442 Talent 2 from Köln also has this problem leaving and Aachen towards Köln.
