help! Not Enough Raw Materials with good Traffic.

[Drengs 18]

Hello there!

I'm having a problem in my city of 120k people.
All my generic industrial places are suffering from a lack of raw materials. I know that most of the time this is due to heavy traffc not allowing trucks to arrive at the industries in time. However, my city has no bottleneck whatsoever. It does have a few red intersections, but no actual stand-still. Also, I segregated my rail lines, both for cargo/passenger, and International/Local. I have a transfer station where the trucks leave the international tracks and enter the local cargo distribution. With this, my city has no rail traffic either. I've done all this and my industries are still getting abandoned. Oh, and I also have local Oil, Ore and a little Forestry industries, which should provide at least some of the raw resources needed. I even removed the heavy traffic ban from some of my districts to see if that improves something, with no results...

 

Is that a bug or something?

Can anybody help me?

I've noticed this as well. I had 2 coal power plants right in the middle of a large ore industrial section. They ran out of fuel, and although my ore industry was booming, they stayed un-supplied. I'm not exactly sure what it is, but it is quite annoying.

This might be a side effect from using the 25 tiles mod maybe, it's the only thing I can come up with.

 

Could you try experimenting with a cargo train station close to the industries that are lacking resources (with outside connection)?

I've got one in my industrial zone, and am occasionally running into the same issue. I'll screenshot it when I get home from work.

I've had the same issue with two different cities. It weirdly seems to get worse as my cities grow bigger past the 100k mark, even though my cargo connections (rail and ship) have both been improved as I grow. My traffic is also pretty good, no major bottlenecks. Lots of "no raw materials" over industrial buildings and I've given up on coal and oil power plants completely. At this point I'm convinced that imports/exports are at least somewhat bugged.

I already had a cargo train with outside connection near my industry, but I added one more in another industrial district and the problem persists. I also have a few cargo harbors close by, for i thought it could be a lack of capacity to import everything, but no change...

I didn't know the 25 tiles could mess this up. I'll try later without it.

Good to hear at least I'm not the only one having this issue...

[Mr_Maison 2,426]

Never got that far to have this issue. How many suites/offices do you have zoned in your city? Offices and educated Cims seems to stimulate both commercial and industry. Not sure if it would have anything to do with this issue but worth a look. Zoning more offices saved my city the other night.

Could your oil and/or ore have depleted its supply? I saw a map yesterday where the player had built a huge oil industry and tapped all his oil then the whole thing turned into processing plants for oil instead of pumping out oil. His map has a whole lot more problems than that, but that alone was wrecking havoc with stuff.

 

Now, seriously, is this a problem with using twenty-five tiles? I just installed that mod because I'd like to have the option of owning a lot more land. I don't necessarily plan on building on the whole thing, more like have various communities and districts. Now you've got me worrying a bit.

[Drengs 18]

@Mr_Maison, well, I have plenty of offices, and since my industry keep getting abandoned, I'm slowly replacing then with more offices, otherwise I won't have stable workplaces and my city can't grow. Seems to be the only solution so far...

 

@Mystrelia, I have the infinite resources mod, so I know I still have plenty of oil/ore being pumped out (I hated how fast they deepleted). The weird thing is that i'm exporting tons of raw oil and ore, but my generic industries says I don't have enough raw materials! I'm almost convinced myself it's a bug...

[Mystrelia 57]

Well, maybe your generic industries want a different type of resource? How's your farming sector doing? I know, I know, don't EVEN ask what the nylon factory does with all those beef intestines. You have a little timber? How many lots? It seems like generic industry can use a lot of lumber and wood pellets.

I'm continuing to mess with this in my city, my whole industry area is basically shut down due to lack of materials even though there are regular rail and ship cargo shipments coming through to multiple stations in the heart of the industrial sector.

 

I'm wondering if I'm running up against one of the agent limits? My population is only about 130K. Seems like industry just refuses to pick up goods for itself. There isn't much traffic in the industrial area, mostly because about 75% of the businesses are abandoned. 

[cromabianca 158]

Is really there such a kind of limit? Culd that be my problem? (see other thread)? :scared:

[Turjan 1,048]

There is some absolute agent limit of 66k or something like that. However, I don't think that's the problem here. 130k inhabitants isn't that big. My city is about double that size, although on only 9 tiles, and it doesn't have those problems. The only resources it produces itself are agricultural and forestry products. I have huge imports that are about equal in size to my own industrial production, so the commercial sector gets fed about half through local production and half through imports.

 

Regarding industry, it's important to level the generic one up to level three. This needs lots of educated workers, so see that you have those. Also, a moderate unemployment rate (3-6%) helps. The "not enough raw materials" message means that you either don't produce enough or don't get imports and products delivered in time.

 

The latter may be a problem on large maps, as the game does not choose relations of origin to target by proximity. With increasing map size, the deliveries may simply time out frequently, if the goods come from the other side of the map. I don't know this though, as I'm still on 9 tiles.

I do have a little timber industry, but not too big. But that shouldn't be the problem, since anything not produced in the city should be imported, right?

I have many cargo stations and harbor close to my industries, so that shouldn't be the problem either. It's getting so frustrating that I'm thinking in abandonning this city and start a new one.

I'm only using 11 tiles, and all my generic inds are inside the original 9 tiles, btw...

I really don't know what else to do...

What map are you using? I'm on a map from the workshop and I'm starting to wonder if if my rails and highways were laid down incorrectly from the start. I'm going to try to make them more efficient by unlocking all 25 tiles and redoing them.

What are your exact numbers? I had about 12 freight stations and 2 freight harbors, which hit capacity at about 18k imports and 3k(?) exports. About a quarter of my imports were raw materials, the rest were mostly goods.
