I do have a problem with cargo,or rather,the production of the factories and mines. I have a supply line (train) that brings coal and iron to a steel mill. Considering the high output and my lines limitations,i’ve decided to upgrade the supply to two lines,using the same cargo station. Problem is,only the new line gets the cargo from now on and the old line gets to drive back and forth with empty wagons. I was under the impression that both lines would be supplied with minerals,not just one. Is this normal or a bug?

As for the steel mill itself, whenever i upgrade one of my trains to a newer model or attach more wagons to increase my cargo transport capacity,the steel mills output completely breaks down and it takes several years until it has recovered. I feel like i’m being punished for upgrading and improving my transport capacities 🙁 Is this a bug or intended behavior?

I’m running the game completely vanilla,no mods whatsoever installed.

Thanks in advance for your answers 🙂

the first problem may be explained by the fact that it makes no sense to have two lines for the same transportation: the supplier would always choose the fastest line. It would be much better to add trains on the same line and add double tracks (or sidings) with signals to manage the flow.

the second problem is (in my view) one of the most annoying bugs of the game. I think it is caused by the fact that the line is no longer operated (and thus gets over the 20-minutes rule) so that the supplier cancels all transport orders. You can often avoid it by buying a new upgraded train and put it into the line before dismissing the old train. But again this bug sometimes also occurs when you change track layout (breaking the line) even if in pause… I sincerely hope urban games fixes this bug.

Ok,i can see your point that using 2 trains on one line would be better than having two. I’ll try to do this as soon as i get the chance,

As for problem number two,so it was a bug after all. I do hope it gets fixed soon, because it makes no sense and punishes the player 🙁 I also hope that the bug with mines/wells/forest not working although they are connected to a factory,will get fixed as well.

When you do some modifications, specially altering rail tracks, roads, etc., some of these packets are destroyed.  Since they don’t reach the intended destination, you’re punished and the working line starts anew.

It may also happen that a working line, with just the same configuration (I don’t know why), won’t recover.  If we knew the exact mechanics of supply-demand in the game, we could, as players, do something about it…

I’ve had a working line that was running fairly well for more than 50 years,until it inexplicably started to break down and refused to eve start up again. I’ve checked every city i’ve been transporting goods to and made sure i was the only supplier. No problem there. Checked the trains and the lines,no problem there either. For some reason however,the factory decided to stop working and i was unable to get it running again.

And of course,there are some factories,that will never work from the very beginning,no matter what you do.

If you open the window of the industry it will give you hint about why it’s not working, in the “details” tab (e.g. try to ship more goods, try to deliver more wood, etc.).

I changed to quicker trains and that was the problem (even that with slower ones the lines were working before like a charm)…

I’m starting to think that production lines are just not worth it (due to a borked system) and the only safe thing is to stick with passenger transport.

The only problems that disrupted my lines were

1) when I made some changes on the line, such as changing stations or rails, that interrupted it (and unfortunately train fever often cancels all output – even when changes are made in pause – and this is really a bug that they should consider fixing)

2) when the frequency of my trains dropped because the line got busier, because of more time loading/unloading goods or because trains were stuck due to signalling or electrification problems

The only other explanation I can think of is that the game (or you) built some new roads which made delivery “by foot” faster than your lines (but it is improbable that all seven cities display this problem at the same time).

If you can, it would be great if you send developers (or even here in the forum) the savegame just before that occurs… maybe with the savegame we could be able to tell what is going on.

After watching a few videos about cargo on YouTube, if found that the details tab in the factory info panel worked for them,but not for me,which is why i never knew what was wrong with the chain. Reinstalling the game helped fix that and now i know what’s wrong: i don’t deliver enough raw materials.

What makes matters worse,is that all the mines i’ve connected to the chain,seem to produce less and less,with some of them not working at all anymore. Could it be,that the resource demand is divided up among the connected lines and that it would be better to have fewer connected?

Honestly,cargo in this game is giving me a serious headache :/
