Stopping Point at Zawiercie Platform 2 Track 2 Broken, Causing AI to Lock Up

[pschlik]

While driving along in EN1, I encountered a huge piling of trains at Zawiercie around 4:30 AM (server time). Almost nobody else was online, which allowed me to freely jump between trains to investigate. I determined that train EC 41102 had a proceed indication at Zawiercie station on platform 2 track 2, but was just sitting there motionless (for over an HOUR!), which must have resulted in the traffic jam. When I took over the train, it still didn't move with the autopilot on.

You can see here that the train hasn't even completed its stop at Zawiercie, but it also isn't clear to load passengers (the distance counter isn't green). I took over from the autopilot and inched forward to see if I could get the passenger loading to trigger. I simultaneously got the message that I could stop the train, and that I passed the brake point, when the distance counter hit 1 meter (but passengers loaded anyway?). The expected stopping precision at this station is completely insane, and that may be why the AI got stuck (perhaps the AI assumed that 47 meters left until the stopping point was okay for loading passengers, but it wasn't).

After completing passenger loading, I told the autopilot to take over again and the train continued as it should have. (80 minutes of delay, ouch!)

After this, I kept an eye on things and it seems like the traffic began to sort itself out...then another EP07 train, TLK 42106, did the exact same thing where it was waiting at Zawiercie platform 2 track 2 for no good reason (only difference is that it was only 3 meters from the stopping point-which still wasn't close enough!!!). I take it over and 'pass the brake point' because the stopping precision is weird, passengers load anyway. Then when I tell autopilot to take over it drives away like it should.

I had to sign off at this point, but I can only imagine the next train to use platform 2 track 2 would just cause the blockage again. The server also reset at around 5:20 so any future trains were a non-factor.
