Train Jams (260k) city
Hi, Thanks for all the work you are putting into this!!!

I have a bit of a problem though. Rather big city (260k). Was running okish with the old Transfer Manger + optimised outside connections (factor 3 for cargo trains). But stuff being constantly transported from the other side of town or import, even though warehouse was right beside the factory (-> idle factories).
Now I installed and tested the new Transfer Manager for a while. First thing that happened was a big traffic jam and all my Warehouses (balanced) emptying.

That slowed down (since they are pretty empty know) but I get train jams and the Cargo stations Are incredibly busy - to the point that there are more than 10 trains waiting in front of the station from both sides.

My settings:
- Distance Algorithm: Path (80%)
- Goods Delivery: Everything selected (40% trucks reserved for local stuff)
- Import/Export: Train Multiplier 3
- Export Vehicle Limit 20%
- Allow Import: Only goods/Petrol and mail

If anybody has a hint, what I can improve, I would be grateful!

Thanks

@StBonifaz,

I am not really sure what you mean by old Transfer Manager and new Transfer Manager, could you give more detail on this?

If you are having trouble with a train connection getting too busy then I would increase it's distance multiplier so it is less likely to get matched. You can press Ctrl+6 to open the outside connection panel which lets you modify settings for individual connections.

You can also turn off import on warehouses and factories so they only get material from within your city. With a city that large you should try to satisfy a lot of the demand internally.

Without more specifics about your map and layout I can't really suggest much more than that, you could log into our discord server and post some images which might help with more detailed suggestions.

Hi Sleepy,

thanks a lot for your reply :). I'll put some comments in your text.

I am not really sure what you mean by old Transfer Manager and new Transfer Manager, could you give more detail on this?

- The old transfer manager is the former one by PCFantasy: https://steamcommunity.com/workshop/filedetails/?id=1680840913
- The new transfer manager is yours: Transfer Manager CE v2.3.32

If you are having trouble with a train connection getting too busy then I would increase it's distance multiplier so it is less likely to get matched. You can press Ctrl+6 to open the outside connection panel which lets you modify settings for individual connections.

- I've put the general Train Multiplier in the Export/Import Tab to 3. I also tested other numbers, but they don't seem to have much effect. Does this multiplier also effect local cargo trains? Because I think these are my problem.

You can also turn off import on warehouses and factories so they only get material from within your city. With a city that large you should try to satisfy a lot of the demand internally.

- Import of both were turned off except for goods/mail and petrol (which i didn't produce quite enough]. But it actually made things even worse. (local transport problem?)

I think my problem is not the outside connection, but the local train traffic. I have a total of 8 cargo train stations, 2 Cargo Airport hubs (with trains) + 4 Harbours (no train). My two busiest cargo train stations - which totally collapse when your mod is running - are quite close to each other separated by a big river (I think its the Black Woods map). Since it is a bit closer to transfer between these two areas by train I have tons of cargo trains (with 7% load) going back and forth between these stations + traffic to the other cargo stations in the city.

To test further I deactivated your mod yesterday and activated the old one (pcfantasy) again. After about 20 minutes rt things went back to normal. Only moderate traffic at the cargo train stations, but allays a couple of the Industries DLC unique factories or processing plans running out of input because stuff is coming from the other side of the map via train and the incoming trucks are marked as "off road" in the Building vehicle monitor. If I delete them there, a truck from a close by warehouse is usually dispatched.

I will reactivate your mod for further testing and join the discord server later. Thanks a lot for your help!!!


PS: Totally off topic some other things I noticed after installed your mod:
- Warehouses still export when 10%-20% full if set on "balanced" mode
- Public Transport went down by about 15% -20% (and went up after I activated the old mod again)
- Tourists went up by around 20%
- If I look at the transport statistics (More City Statistics mod), the amount of trucks stayed the same after activating your mod, but the amount of "Cargo and public transport" went up quite a bit. Since there was no big change in the number of public transport vehicles, I think this is all due to more cargo trains.

@StBonifaz,

I think I would need to load your save game to really see what is happening. Are you able to share it on Steam?

Wow, that mod is way outdated and doesn't support a lot of the new features added to the game. I am surprised you can get that to work at all.

- I think my problem is not the outside connection, but the local train traffic

It sounds like you have a lot of cargo unnecessarily being transferred around your city. Have you tried using the district restrictions to optimise the flow of material?

- Warehouses still export when 10%-20% full if set on "balanced" mode

Warehouses will export when their OUT offers have a priority of 2+. You can see a warehouses matches on the "Transfers" tab of the building panel (Ctrl+4). In balanced mode this is normally above 20%. Are you sure they are actually exporting?

- Public Transport went down by about 15% -20% (and went up after I activated the old mod again)

Probably because the matches are closer with my mod than pcfantasy's so they are walking or cycling instead. In my highly biased opinion, my mod is light years ahead of pcfantasy's mod but feel free to use any mod you like.

- Since there was no big change in the number of public transport vehicles, I think this is all due to more cargo trains

Without seeing your map, I cant really give any advice here. Different transfer managers will match offers differently so things will work differently within your city.

Hi Sleepy, thanks again for the super quick response.

Uploaded the problematic save-game to the workshop. Hope this works, because I use a lot of mods and tons of assets - not sure if it's worth the hassle for you, but you are welcome to try :).

- yes, I know. Stopped playing for over a year waiting for Colossal Order to stop their update orgy, which rendered many mods useless for a while. And I know the mod from PCFantasy is outdated, I also hardly see any difference if it is activated or deactivated (just 'warehouse first' seems to have an effect. But I just discovered yours a couple of days ago.


It sounds like you have a lot of cargo unnecessarily being transferred around your city. Have you tried using the district restrictions to optimise the flow of material?

- no, I have not tried that yet, but definitely something I should do. i just wonder how that works for the agrigculture/forestry/oil/etc. industry pre-products though, because they need to get to every district that has some industry.

Thanks for your help!!

@StBonifaz,

So I have had a bit of a look at your save game, I have noticed a couple of issues:

1. Some of your train line intersections seem to be missing links so cargo trains are forced to go in different directions than would be ideal.

2. You are producing enormous amounts of crops among other materials, but with very little need for it.

Normally this would be exported for profit but you have turned the "Export vehicle limit" option down quite low (20%) and also don't have many crops warehouses. This means that the outside connections can't be matched and so it is just being shuffled around your city.

If you want to have a large industry area to make lots of money then that's fine, but you need to ensure it has a very efficient connection to the outside world so the material can be exported effectively.

Hi Sleepy,

I'm very impressed that you got that savegame to work, with all the mods and assets! First to your comments:
1. Some of your train line intersections seem to be missing links so cargo trains are forced to go in different directions than would be ideal.
- Yes, I admit the train network looks a bit messy, but actually every cargo station has direct access to every other station as well as to outside connections. I believe the strange intersections you saw are a result from decoupling big chunks of my public transport network from the cargo/outside tracks.

2. You are producing enormous amounts of crops among other materials, but with very little need for it.

- I was young and I needed the money. Thanks for the hint I will put the export limit up again and check out what is happening at the barns.

Regarding the original problem, I think I'm slowly getting on top of it. Following your advice I changed most warehouses with non locally produced industry input to local district only (sometimes also neighbouring district) and no exports. Also all unique factories input. I'm still a bit reluctant with all the generic industry because I'm not sure my warhouse network is good enough, but the cargo-train traffic is already reduced quite a bit. One other thing i did was cut the direct connection between the two close-by cargo stations, where goods were shipped back and forth.

I also tried again to shut down the import of everything except goods and mail, but switched forest and oil products on again, because many factories started to complain. I would really need 8 warehouses in each industrial district to make that work, right? - the generic industries don't seem to accept e.g. paper or timber, rather some accept only paper, others only timber.

Nutshell: Everything works much more smoothly now. And the micromanagement capabilities of your mod are really great. Thanks a lot for the mod and your help!!
