The Train Drain - Gridlock LEAVING city
I keep running into this problem where my train lines are solid bumper-to-bumper LEAVING my city. Train after train is stopped lined up two dozen deep off the edge of the map. Most of them right now are cargo.

I think this is what is causing my warnings and abandonments - gridlock.

What am I doing? Producing *too much* goods and products that exports are congested?

It could be a faulty map.
Follow the trail of the trains and check if they stuck at the end of the map.
If so a) exit the game and steam and start the game
b) delete the 1st train and check if it is fixing it
c) check if the train is stuck because it is a longer train

Sorry. By "off the map" I mean literally to the foggy horizon at the edge of the game area.
I can't edit there - I can't even see that far.
(Attached screen shot is just to show you the game edge - lost in blue mist.)

Those trains are LEAVING the city. Like, the outside world is full up, and can't take any more trains.

It is usually not on the tile border the issue, the issue is most likely in the fog area. the physical end of the map.
I had a map like this before and can fix it with a map where you can edit outside connections. forgot the name of it.

You probably just have too many train stations on the same track.

If your trains are not 100% full, then you have too many train stations.

Hopefully you have several train outside connection. You can then segregate them so trains can't cross over to other outside connection.

Ultimately, you should have 4 outside train track connection. Then you can have one supplying each of the North, South, East, and West sides of your city. Just don't let them connect to each other.

Other than that, you can try to eliminate import and exports as much as possible, as they are the usual suspects. No import/export, then no freight traffic. It's impossible to eliminate completely without removing all commerce/industry. But is you can balance supply and demand enough, you can make it work with ease.

You love trains too much, and should stop hoarding them.
Wish for the option for cargo lines and the end of magic trains.
Taking the train traffic off the main line, not all going to one spot etc.
To the things that was talked about in the above comments, if that's your issue.
Also cargo trains can multiply, so before you know it, you got more trains than people.

try this mod to reduce the number of trains that spawn.

You may need to download a mod that hides edge fog as well as let's the camera move outside the 25 tile area to properly diagnose the issue..

If the jam runs all the way to the physical edge of the map and the exiting trains are not despawning, you may have the faulty map issue mentioned above.

If you see a train stuck, unmoving but with nothing physically blocking it, it might be a glitched node. You can use tmpe's lane connector to fix the node temporarily to get traffic moving again, but once the jam clears you should eliminate that node entirely. Bloody penguin has a mod that allows you to construct infrastructure outside the 25 tile area. Delete both adjoining segments and rebuild it so there's s new node there.

If neither of those are the issue, check how full the trains are. If the cargo trains are all below about 21%, you have too many stations attached to your train network. Segregate your train lines into external "international" networks and one or more local networks depending on how extensive your network is and construct cargo transfer stations to connect network to network. I generally find that with the base cargo station you can typically have a network with 5 to 7 stations depending on distance between them and how they interconnect. If you use bloody penguins dual track cargo station correctly your networks can get much much larger as each train will despawn at its destination rather than be partially filled and sent along, which inevitably leads to 7% filled trains clogging your lines. See the tips above as well as the optimized outside connections mod. That mod in concert with the double track cargo station and no vanilla stations will allow you to create enormous networks if you build it right.

If your problem is passenger stations, segregate your passenger lines into stations that have external intercity access and the stations that host your passenger limes. The fewer that have intercity ability the better.

Additionally, if you're seeing a flood of zero passenger trains, trace it back to the stations sending them out and replace it with another station. There are a handful of passenger stations that, when connected to the external lines will, regardless of the intercity permission, just spam an endless stream of empty trains. Use these stations on isolated internal lines only.

Train traffic is infuriating once you reachate game.

Correct me if I'm wrong, is there not a button to delete all traffic and let it flow again? (if not there is a mod for it)

Not in the base game, you need a mod like TMPE to reset them, but the traffic will just clog back up until you fix the underlying issues first.

You know, I hadn't made this connection (pun) with an earlier problem I had.

When I first started this city, I noticed that the pre-existing outside lines had glitches in them. Trains zooming along a perfectly straight train, all by themselves would suddenly try to reverse direction, its engine flipping back and forth multiple times before proceeding.

I destroyed and replaced the section and it would be OK, but the the train would just that that a few cells away.

At the time, when traffic was low, it didn't seem to be more than an annoyance. But if that's happening on the lines outside the city, that would definitely cause a pile up like this.

I can't be sure if this is a starting map out of the box or one I downloaded. There seems to be no way to tell without starting a new city with every map I have just to see what it looks like.

I thought it was Foggy Hills (there's a lot of fog), but it doesn't look the same:

Will it allow me to do this on my existing city? I will go look for that. Any idea what it's called?

Yes you can use it in an existing city. I believe its called cross the line.

OK, all mods installed!

I can see at least one problem: tracks at the edge of the city always have a crossover section right before the edge. It can't be avoided.

Also, the trains stop at the edge to pick up hundreds of passengers coming in from out of town.

So what happens is a train will stop in the middle of the crossover, preventing all other trains in both directions from moving until it's done.

I suspect this is by design. I suspect it's a deliberate in-game limiter on trains.

Cargo seems fine, but passenger trains are almost empty.

What is a cargo transfer station?

This?

What is a vanilla station? You mean NOT the above...

Not sure I follow this.

If I find a passenger station spamming trains I should destroy it and build a new one there.
How will I "use" a destroyed station?

Or do you define a station by its location? i.e. A station in a given spot will always spam. I should disconnect it from the inter-city network and allow it to only connect to internal routes? That muut be what you mean.

Yes, it is by design. The only way around it is by segregating the outside tracks from one another. If you have two outside connections, this will cut it in half. If you have 4, then it will reduce it by 75%

I usually make at least one for passenger trains only. then the other for freight, as freight has a lower agent limit and can max out early in the game.
