Not enough raw materials! Help please!

[Qubk0]

I have this city for a while, and its my biggest one yet. But after I reached 70k pop my factories started complaining about not having enough raw materials.I´ve tried placing some Cargo Train Terminals, but no trains appeared. I would appreciate if you could maybe take a look at it and tell me what i can fix. Thanks :)

I managed to make one of the cargo train terminals receive trains by rebuilding the nearby underground connections, the angle was probably too sharp so the rails weren't connected. Getting trains in solved most of the raw material availability issues (and consequently made the highways slightly congested).

Generic Industry requires materials to create goods for supplying commercial and or export. Generic gets its materials from specialized industry ( Forestry, Oil, Ore, and Farming). If your city does not supply these materials (through specialized industries) in your city they must import. You have a great deal of generic industry and no other in your city. If you are to continue this way you will need to better design ways to bring in, import the materials and deliver them to industry without delays. Keeping in mind the industries (Generic) creating good that are leaving those districts.

With access to only two rail connections, no water connection and three highway connections. I would suggest converting some of the generic to specialized industry then create a local rail line/loop from them to the generic district to move materials by rail. Reducing their traffic through your city. Oh and if you don’t place the proper specialized industry on the natural resource they too will require imports, defeating the purpose of them.

one thing about relying on heavy internal rail is you can get rail traffic jams. The following screenshot is my current way I love to do rail yards to prevent line crossover and jamming.

Yes never forget a bypass line.

Ok so when while setting up the districts I noticed you have specialized districts though no resources beneath them so they too are importing. Your forestry district has no trees. Farms are not on fertile ground..... this is an issue.

[Markus Reese]

the trick to that one is by having the main line run under, with exit lanes to the yard, it cuts out all crossovers and keeps it compact. Doesnt lock up that way. It can back up, but trains can always get out. That map had no outside rail or water connections, so it was all internal and by planes. Cargo airports, had a few that were very busy. Unfortunately lost the save...

Place a cargo airport

The biggest problem you have is the insane amount of one-way road in the industrial district and killing road imports. I just turned all roads into two-way and everyone is happy.

However, now you have insane traffic now that it flows properly. It's not clogged, but very heavy.

I first bulldozed the passenger train, as you already had a metro station to handle the working getting to work. and replaced it with a cargo train station to alleviate the freight traffic, then bulldozed the other two cargo train stations as they were just adding more traffic to your industrial area as they came in the same was as everyone else.

You didn't place your forestry in the forest resource area, you provided no oil or ore to your oil and ore districts. You forgot farming district.

Only the generic industry provides for your city, and it is way too small. Also, generic industry should be 4 times larger than all of your specialized industry. so 4 generic industry, to 1 oil, 1 ore, 1 forestry, and 1 farming. (4:1 ratio)

As an example, you have no oil in your oil district. So an oil truck drives in from off the map, goes to oil refinery, drops off oil, then the truck drives back out of town. The the oil refinery delivers refined freight to generic industry, then drives the truck back. So there are 4 truck trips.

So, if you had no oil specialization at all, then refined oil would be imported directly to generic industry and then leave town. then it only hake 2 truck trip, instead of 4 like above. This will cut your traffic in half.

If you put oil resource in the ground and zone oil specialization, then it can extract raw oil, deliver it next door, create refined oil, then deliver refined oil a few blocks away to generic industry. Then you don't have trucks importing freight for miles on your map to and from the outside connection. This can cut traffic tremendously.

You water pumps were draining the river dry. I had to add another water spawner with ELT.

The toll booths slow things down a little, but I left them as it wasn't holding it up too bad. Once oil, ore, and forestry catch up with have resources, and moving the cargo train stations in the middle of industry, freight is getting a bit lighter now.

Commerce is a bit spread out. It likes commerce districts (shopping malls) like residential and industry.

Everything is on a timer in this game, so it works easier if things are in proximity of each other.

Here's a strange thing that happened, when replacing the passenger train station with a cargo train station right behind the metro station.

I was redoing the pedestrian walkways (that still don't seem to work properly) when I noticed cims cutting through the metro/cargo train stations. I apparently lined up the subway station with the cargo freight garages even back-to-back and it turned them into an intersection. And it's working for vehicles as well. lol

Very weird!

Wow it made an intersection through the Cargo Terminal. That one is odd ! Nice clip.

Changes
-The structured industrial area is now generic only rather than four specialized industries which needed to import all their materials.
-I replenished the resources under your other specialized industrial districts.
-Did roadwork to interchanges and intersections to increase flow to 82%.
The issue of “Not Enough Materials” is now gone.
This is not vanilla. I believe I saw Network Extension2 road pieces. I Think it should open with just that for I did not download any items from the original save. The other 2000+ items are not required. I hope
Edit; I have yet to deal with the rail or create that line mentioned though I will, and share. Nice city. The value throughout is great so far.

One thing to note, some materials can't be imported. On my map I created an Electronics Factory (which requires plastic among other things) only to discover that plastic can't be imported for whatever reason. So I had to create a small oil industry area, even though I had to import all the oil, just to make plastic.

Even without access to local oil, it did eventually level up and start turning a profit (but took a long time). I made sure it had its own connections to highway, rail, and ship routes, so the only traffic was from shipping the plastic to the factory. It worked well once it got up and running, but did take years of running at a loss to reach that point.

(If you do this, don't forget to set the warehouses to Fill, so you aren't exporting your imported oil...)

This advice is only for zonable industry.

Industries DLC has a few extra rules that don't apply. i.e The OP isn't using Industries DLC.
