I got my ice3m upto 230mph,so if i remember correctly this is this trains max.How i was able to avoid derailing on the curves is beyond me,it was only a redlight that got me.i think the speed limit on that section of track was 124mph at the time.i passed another ice3m going the other way he came and went so fast it was like a blur to my train.
330 km/h is the BR 406 DB / ICE 3M max designed speed but on Köln-Aachen the max operative speed is "only" 250 km/h.
