I've noticed that the AI on the Talent 2 for Riesa to Dresden seems to turn the batteries off which sometimes leads to double units not having the rear unit powered (no passenger lights or tail lights). It also happens if you take over from an AI train, which means having to run back and turn the rear unit coach batteries back on. I experienced this by spawning on foot at Großenhaim at 09:25 to take over the 09:28 RE15 to Dresden. I thought the AI couldn't start up and shut down trains? Or is this a new sort of test feature, implemented on the Talent 2?
