I've explained this "neutral section" back in March: https://forums.dovetailgames.com/threads/pf%C3%A4lzische-ludwigsbahn-feedback-thread.88852/page-8#post-979564
Aaand of course I thought this service was cool to see, I spawn there at 7:50 and it's made of 101+DB IC wagons, and never moves, locking all other trains on nearby tracks too. Cool, DTG, another bug! Can't have one cool thing...
I just tried it on both timetables, it works if you spawn in at 7:45 on my end (PC/Steam). Probably 7:50 is too tight for the dispatcher to calculate a valid path in time.
Thanks, great info. I do guess then this is the base issue that causes random gridlocks while playing timetabled services, what if I spawn in a service at 7:50 in Kaiserslautern bound for that platform....
