Aachen to Koln on service mode has red lights ahead of it and causes the ICE train to slow right down from its normal speed
Normal behaviour because of a Talent 2 ahead. I think they did it to show how LZB limits your speed when it sees a restricted/danger signal further up the track. If you want to not be too late (AI runs are a little late btw), you should assist with braking and coast at a lower speed. Then you won't have to come to a complete stop at the signal. If you let LZB do everything, it will stop you at the danger signal.
