Hmmm... working on a different timetable for HRR, I came across a strange problem... both trains run with the original BR 101 (as they didn't run with a cab car; and yes I know, in real life it was a consist BR120, Aimz, Bimz, but not available, and I'm not convinced, that I'm able to create these vehicles...but that's another page...). It's the second and the third run of the consist, and the first runs haven't had the same problem...so, how can I stop the consists triggering door lock state for two hours, and causing a big traffic jam?
What exactly is the formation that you're using? And are you doing any coupling/uncoupling in the vault?
It's a formation from Kassel-Würzburg , BR 101+9 waggons...(BR 101+3 Avmmz+6 Bpmmz) no couplings in vault, as it somehow comes close to the original (real life) consists...BR 120+2 Aimz+1 ARkimbz+6 Bimz....(loco+9 waggons, no cab car).
I've only ever encountered this problem on the 101 after changing up a formation in the vault, so I'm afraid I don't know what's going on in your case. Sorry!
