Major bug with AI trains (repeatedly)


Recommended Posts

(this topic is reaaaaaallyyyyy long, but I recommend to read it to the end)

Hi,

I would like to report a major bug. Sometimes, when you probably leave, AI dispatcher (on place like Lazy, Lazy La, DGZ and Zawiercie) and AI train will be bugged. For unknown reason, AI dispatcher won't give to this AI train a way to leave the station (green signal). Due to this, it will result in that station will be completely stopped and nobody will drive through this station. I easily solved these 3 situations in the last 2 days and they was everytime completely same.

Picture 1: Station is completely stucked, nobody can drive.

For now, there was bugged trains on server CZ1 at the station Dabrowa Gornicza Zabkowice. I was stalking online map and all trains (AI trains) in the station was waiting for green signal for like 5-10 minutes without any response). I checked number of trains - it was 41116, 644024, 242219. I tried to join 242219 first - woah! I got green light in the first second after joining! I drive away maybe 1-2 kilometres to Dabrowa Gornicza and then I left the server. This bugged train drove only to Dabrowa Gornicza and it's bugged again. AI dispatcher didn't register this train and it's blocking the way again. Somebody have to join this train or nobody will drive.

Picture 2: AI Dispatcher + AI train. AI train can't move, because AI dispatcher cannot "see" him.

Things moving on in Dabrowa Gornicza Zabkowice! Since I drove away with this train, some trains passed the station Dabrowa Gornicza Zabkowice. But there was probably another bugged train, because after a few minutes, AI trains won't move again! Every AI train has red signal and nobody moves again... I joined another AI train in the station - 41116, which was waiting here for the whole time too. Woah! Green light again! I drove away and I rather derailed the train, so it will not be stucked at the next station. All trains starts moving, good job! After a few minutes, the station was completely clear, only passing trains were driving in this moment. 

Picture 3: Station appear to be clear, there are a few passing trains through station without problems.

But let's go back to the train 242219. He is still waiting at Dabrowa Gornicza Zabkowice for a few minutes and 6 trains got stucked waiting behind him. I joined the 242219 again and what do you think? I cannot drive the train, I have red light and AI dispatcher won't give me a green signal even with using ZEW1 and ZEW3. I checked the online map - there wasn't any train ahead me and AI dispatcher wasn't reacting, so I decided to join as dispatcher, but somebody took it meanwhile I left the server. So I joined back to the game as 242219 and I saw that somebody already join the station. After 15 seconds, human dispatcher give me green. I left the train and I was patiently waiting, if he starts moving. Finally, 242219 starts moving! After our intervention (me + dispatcher František.b), the train finally starts to moving.

Picture 4: Moving train 242219 with another 6 AI trains waiting behind him.

Summary:

Unfortunately, this is not first time. I already fixed two same problems at Zawiercie yesterday (4th January), where one passenger train bugged whole station for 1,5 hours. There was only one passenger train at the station and he was waiting for 1,5 hour red signal. I joined this train and I got instantly green light. I drive to Lazy La, but I got red signal for like another 10 minutes - nobody was moving around me. There was probably another bugged train... I check online map and I saw, that there is one cargo train at red signal which appears to be the problem. I joined this bugged cargo train and after trying ZEW1 and ZEW3 on red signal, I decided to derail this train (since AI dispatchers wasn't reacting). And I did good job! All trains starts moving after this derail and both stations got clear in like 30 minutes. I win again! But for now, there was enough of winning, it will be better to fix this bug. It's looks like that this bug appears only when there are only a few or no players online, because I play in specific hours (when everybody sleeping) - late nights or mornings. But I never see this bug during rush hour (when everybody driving). This is why I think that there will be some big bug with AI trains. This problem was never on human's station. Everytime I see only bugged stations, where the traffic is controlled by AI bot.

EDIT1: Unfortunately, this train 242219 bugged also Katowice station, I could not get the trains to Katowice Zawodzie. And as a bonus 242221 bugged Dabrowa Gornicza again and he is blocking the rail (it's AI train).

With Dabrowa Gorniza Zabkowice i got the same traffic jam yesterday, but from one moment to the other, the AI Dispatcher got it handled..

Sometimes it helps jump to the train that may be not driving and everything start again working.

5 hours ago, thenavvy said:

Later kojonek2 manually set a rout for 4122 and got things moving. But only on that line. 42924 was still stuck and later 41122 was also stuck before Katowice until server restart.

From what I could see junction 86 was lined (in plus) against a route for 42924 to be able to move. While junction 91 was also lined in plus so no train was correctly lined for platform 4. I did not inspect junction 85 (or 81) to see whether any route was aligned for platform 3. (Assuming Kawotice northbound is still using even tracks.)
