Trains getting stuck outside city boundaries

[rx12345]

Hi!

Anyone else experiencing this problem? Trains get stuck trying to leave the city. The problem is outside city boundaries, beyond viewing distance.
This is causing major train jams inside my city.

Yeah, same thing. They should despawn when they leave the city but they're doing it faaaaaar too slow.

Here's a explanation what's happening: https://forum.paradoxplaza.com/foru...ported-from-steam.844909/page-2#post-19216511 - Maybe some modder experienced with vehicle AI could look into it?

My workaround here is to separate outside connections from city tracks. I build two cargo stations, one for the city track line, one for the outside connection, both across the street from each other, in a quiet part of the city. It's not optimal, but working for now. Otherwise train traffic would ruin business and industry since they cannot import/export.

not necessary. trucks only ever go to a single station anyways. they ignore all other cargo stations. if an 'export' does go into another station, it will exit one of your other stations, then drive to the station thats closest to neighbour connection, and a queue will build up there.

shipyards work the same way, but they actually load balance to some extent. build 2, and they will use 1 sporadically, build 3 tho, and the 3rd is almost always unused. you end up with giant 1km queue basically.

you can test this too. build an industrial district (ie: agri), build a cargo station near the exit of the district, which is 1-way only, same for entrance. cut the exit. all the trucks are forced to use station, but will instead exit the next closest station then drive by truck to 'main neighbour' station.

yes, this is also a bug.

Hmm I'm experiencing something different. Factories ship to the closest cargo train station. A train spawns and deliver the goods to my outbound station connected to the city train grid. Trucks then spawn from this station and enter the other station across the street, the one that has the outbound connection, which spawns a train going for other cities.
I don't have truck traffic problems if I position cargo train stations close enough to industrial zones. Problem is, if I do connect my city tracks with the tracks that leave the city, the number of trains spawned jams everything. They seem no to despawn fast enough when they reach map boundaries.
My current city is around 110k population, 5 different industrial zones with cargo stations on each one of them, and a few cargo stations close to commercial districts as well. It works really well as long as I don't connect the city tracks to outbound tracks.

if i try that setup, then instead of trucks going to the closest cargo station, they go to the cargo station that has the shortest rail connection to this 'export' station.

i had an issue with a 'colony collapse'. didn't see a jamming problem (i also separate my cargo+civil train lines). but i disabled the industrial space policy, and big business benefactor for a few months, took a huge balance hit, but it reduced the exports for a bit. re-enabled them, and it fixed itself... for now...

Yes, this is a well documented issue that the devs are aware of and say they will do something about. This error ruins every one of my maps. It's been known for 2 months and still nothing has been done. Starting to feel like an EA game now...

You got to be joking? Have you been blind for the issues they did solve over the past 2 months? Just that your issue isn't solved yet doesn't bring CO or PI anywhere close to EA. Appearently the fix isn't easy.

Any word from the devs about this problem? Really stuffing my cities up. Almost no point playing this game anymore until it's fixed! It's not an occasional bug, it is constant.

This issue is being investigated.

This works for the local services, but the outside connected stuff still gets stuck. I noticed too once this happens, the performance drops like a rock in a bucket of water. After the queue cleared on one of my cities, the speed came back to something reasonable. My thinking this is caused by all the AI traffic retrying to leave, meaning that each train is constantly checking the queue to see when it opens up for them to go out of the city. If for some reason there's a backup in the queue, we have all these trains checking at once, which is flooding the data queue and causing the performance to slow down.

The next time this happens, cut the track where you can so the trains clear out, and you'll see what I mean.

Hi all,

After the snowfall release I cleaned my list of installed mods, after which the trains stuck on exit problem reoccured. For me installing the "Traffic Manager + Improved AI" mod solved the issue: http://steamcommunity.com/sharedfiles/filedetails/?id=498363759
Hope this helps anyone
