On the SCHNELLFAHRSTECKE NURNBERG- INGOLSTADT I’ve noticed that the AI trains are not reaching the target speeds for some reason looks like they’ve gone back to their own bugs cause it was like that on the West Coast mainline for little a While and it’s like it on some of the trains on the Birmingham to crew Route as well cause on the fast section they’re supposed to go up to 300 km but the only weeks in 280 km which is a bit disappointing. I don’t know if it’s a performance issue on something else. I just thought I mentioned it in case less something to note down for the team to fix I’m playing on PlayStation five
This is not a bug but intentional. It was mentioned in TrainSimPlay's German preview stream. The AI always departs perfectly, accelerates perfectly, and brakes perfectly. That's why the AI's speed was capped at 270–280 km/h so that it wouldn't mess up the whole timetable.
