Freight issue - cargo on the wrong lines
Hi, I have an issue that I can't get my head around, I have a large cargo chain from a goods factory supplying goods to 3 separate cities, using initially 3 lines from the factory itself, later branching into other lines. The issue is that the factory is only or almost only placing the goods on line "C" at the freight train station it's hooked up with, line C only goes to a small city with a low population and low demand, whereas line A and B both go paralell to cities A and B. The trains that are on line A and B have 10 boxcars to transport goods, in opposition to the 2 line C trains that only has 3 boxcars each, moreover the demand for goods in city A and B are pretty much double that of city 3, so just WHY is the goods factory only using that line?? Screenshots provided. Automatic or dedicated Goods cars doesn't make a difference. forcing the line C track to go onto the line A slot just moves all the cargo over to that track, so the station / factory is definitely prioritizing LINE C... but why :(

goods are fickle beasts. i'd try waiting a couple of years and it will even out a bit but you might see some odd things like steel slowly creeping up towards your goods factory if you use trains for supplying that specific area

No trust me it's not a waiting issue :/ I probably had that specific set up for over 20 years without difference. year is currently 2111, I botched the C line and are now running goods just to A and B, but now I have the same type of issue (actually had this one before too), on the other side of the chain, the stone delivery (by train) to the materials factory, I currently have 2 trains (on separate lines but from the same station) equipped with stone cars, but the Quarry is only putting the stone on 1 of the lines... again not a waiting issue.

@ArcBird with your stone transport, you should only use 1 line for supply. Two lines will compete with each other, with one getting the bulk. If you need to add capacity, add more trains/wagons to the supply line.

The goods production is tricky, there are many steps that can have a problem. I would look at the last mile in the A and B cities, check coverage, check truck frequencies. Bottle necks and and slow lines can stall production. Also make sure there's enough material supply to meet all the demand as well. It also could be that city C is simply starving A and B because C has a better fequency.

Of what you said, it's most likely the frequency, if that mechanic is indeed true, I find it difficult to understand all the hiddden mechanics in this game, in train fever there was the 20min rule which was pretty easily worked with, but here we have catchment areas and demand, which I've learned and mastered quite well I think, there are no bottlenecks or low frequency runs to city A and B, however the line itself from the goods factory to those cities is much longer compared with the line to city C. Btw, how the hell do you make a large truck line work within a large city ?! We need waypoints but for roads, to direct the traffic... I simply can't find a way to solve THIS:

You can use busstops as ad hoc waypoints, trucks will stop for a bit, but at least you more or less configure your own route.

Concerning inner city truck problems. Rule of thumb is that trucks, and all other traffic for that matter, should be in constant flow as much as possible.
It's tempting to just throw more trucks on a line that is having capacity problems, but as you learned the hard way, there is a limit to what roads can handle.

In such a situation i would, first, look a the city road network, make sure the trucks are using 4 lane roads (at least) and dont share paths with other lines.

Then, if the truck line is suffering from pedestrian/car delays, that is a sign that your public transport network is not up to par and should be refined.

After that you could look at making dedicated (underground) roads for trucks, but more effective would probably be to split up the truck delivery system into multiple lines.

Finally, and that's more the case for really developed cities, you have to consider that if a city demands over 1000 of each cargo, that is a whole bunch of trucks you need if you want to cover that demand. In such a scenario you might want to consider using train lines for delivering the bulk of the cargo directly to buildings and a small amount of truck for the rest.

More screenshots would be helpful. Of the screenshots you've provided, I'm feeling like there's one or two pieces of the puzzle that are missing that would explain what the issue is.

Since it seems like you like multiple wagon types on your freight trains, and Goods are flowing to the Wood line almost exclusively, where are the goods being dumped off to exactly? How are they getting to their destination? Can Goods on the Wood line find their way to the other two cities some other way? Either by another train line or truck line? It seems like they can, and with how it seems like there are goods showing up in places such as the Forest and the Stone Quarry, my guess is that the Goods Factory doesn't need to distribute Goods out to the other higher capacity lines because the one line (Line C) can satisfy delivery to where the goods need to go. In this case, the game doesn't care if the other lines have both a much higher capacity and a more direct route to get to it's destination. This is why parallel freight lines often fail.

In the case of your truck issue with a long backed up line of trucks, I'd recommend instead to drop off the goods to a truck station on the outskirts of the Commercial or Industrial area, and then run the last mile of delivery in the city with a separate local freight route, so you don't have the issues of a ton of trucks trying to make their way through the busy city. A shorter local route will allow you to run less trucks, so less issues with traffic, and just as good frequency.

A few months back I was throwing around the idea of doing a Transport Fever series on Youtube I was going to call "Transport Fever Train Wrecks". The idea was to take maps where there's some issue, diagnose the issue, and then provide a solution on how the problem can be dealt with.

Thank you both, I removed the bus stop where the trucks were stopping to deliver the goods/material and instead placed a large truck stop that covers the entire industrial district, I still have to run the same trucks through the city though to get to another truck stop that connects to a trainstation which carries freight to another city, (Corona, if u look at one of the pics). I also moved the busline that was using the same streets and now it only intersects with the truck traffic on a small part, also sold about 20 trucks from both the goods line and the CM line since they were'nt needed, overall the traffic through the city flows alot better now, though there is still a big ♥♥♥♥♥♥♥♥♥♥♥ in the midle, but it is flowing smoothly.

Furthermore I switched from multipurpose trains having several types of cars to single purpose trains with all same cars, which fixes the platform cargo line prioritzing problem (mouthfull), just working on making them profitable now. It seems that multi purpose trains only really work if you have a single train from station to station which I have on another line.

There is one more issue (as always), the goods train from the goods factory has a 1 minute longer frequency than the goods train that picks up those.. goods, resulting in 1/3 of the trips running empty, how do I solve this? Having the trian wait for full cargo doesn't work since the first train doesn't always deliver that ammount and it would be sitting there waiting for 2 deliveries from the first one.

Pardon my terrible explanation lol..

As a sidenote, idk if this is something people use but I found it a good way to stop the city street expansion: http://i.imgur.com/WpUwXCI.jpg

(so that the street doesn't connect with the truckline street and alters the route.)

Another place I take a look at when a production chain is having issues is the numbers for each of the steps in the process. The math should work out pretty close.

Look at the goods potential for all cities connected to the factory.
Look at the goods factory goods potential. It should be close to the sum of all the cities connected. Compare that to the actual production rate.

Then work back through the materials chain looking at the requirement number versus the potentials back to the raw sources. Again see how potential and actual productions match. Then check the storage of cargo at each factory.

When balance is reached, these numbers will balance as well.

What you look for is the goods potential lower than all three cities combined. If it's down by one city's value, then there is a delivery problem.

Not entirely sure what the problem is ;) But I've found that sorting out issues is usually down to selecting specific goods units for trains, ie only slag or only stone, if you have just 1 unit that is carrying general goods.. before you know it, you'll have a platform covered with cows.

Also as said above, check back through your cargo runs to make sure the items you are hoping for aren't travelling by the scenic route.. ie the construction is actually being chosen for lines a and b, but it isn't being sent via a or b, it's being sent via c to d to f to g then to a. etc.

It seems that multi purpose trains only really work if you have a single train from station to station which I have on another line.

Multi-purpose trains can work if you can consistently supply goods that will fill those wagons on each of the trains trip. For instance, you might have a train that runs between four towns with Stake Cars. One one end of the line you have town A producing ConMat that is hauling Construction Materials to each of the towns on the route. At the end of the route at Town D you have a Steel Mill. As it turns out Town B has a Machines Factory, and so the idea being to haul ConMat going from Towns A, B, C and D, picking up Steel, and returning back, stopping at Town B, making you some cash for the return trip, before running empty back to Town A.

Goods wagons are even better. Town A produces Food, Town B produces Machines and Tools, Town C produces Goods. Train picks up a full load of Food in Town A and drops half of it off in Town B. Loads up on Machines and Tools, and then dumps everything off in Town C. Train picks up a full load in Town C, and returns back to Town B dumping off half it's goods, and loading up on Machines and Tools destined for Town A.

You might even have a town on the route that has a Farm, and thus your Goods train can take Livestock from one of your towns to the town with the Food Processing Plant. You might also have a town or stop that can pickup Plastics to be delivered to the Goods or Machinery Factories, no need for a separate line. If the route is long enough, it just makes it even more profitable to run multiple really long freight trains. Profit!

You can run mixed trains, though that ideally only works well, if you can fill most of the wagons most of the time for trips running in each direction. Stake Cars with Goods Wagons if you have sufficient quantities of relevant goods being produced in different parts of the line. Otherwise, if a route only has a single ConMat Plant, on one end of the line and thus the train is running empty back the other way, you might be better off running dedicated trains for those goods.

There is one more issue (as always), the goods train from the goods factory has a 1 minute longer frequency than the goods train that picks up those.. goods, resulting in 1/3 of the trips running empty, how do I solve this? Having the trian wait for full cargo doesn't work since the first train doesn't always deliver that ammount and it would be sitting there waiting for 2 deliveries from the first one.

One option if you have trains running under capacity or where production is not great enough to constantly keep the train loaded full is to remove some of the wagons off the train. You might be able to get it to a point where it picks up just enough that by the time it returns for a second load, it can load up full. This can help save on running costs, and if it's a situation where one out of every three trips is hauling empty wagons, that's a train that's just costing you money. Better to reduce the capacity, which might help slightly improve the frequency since the reduced number of wagons will allow the train to accelerate faster, and thus get up to it's top speed sooner, allowing the train to improve it's frequency.

That's an interesting idea. Rail will definitely block the city from creating new roads where you don't necessarily want them.

TL/DR

I've run into this issue in the past. The answer I got was simple and it works!
If your running two seperate tracks to the same place and back...when you build the trains, or after, make sure that BOTH trains are set to use the same CREATED LINE(The one that you create, not the track) You do not need to create crossovers and switches and such, only at first to allow your second train to get to the second set of track. They will use the two different tracks(as they should), and you won't get that only one train(at a time) ever recieves goods. They will still "Compete" for goods but, if I understand you correctly, the supply should increase(if you have enough demand), to the point where both trains will be getting plenty of goods at the production station. Also, the station will no longer only stock product for one track, but whatever train arives will get ALL available goods. The game will even self-adjust the trains(over a short period), to where they are not showing up at that station at the same time. Pretty neat stuff! Given enough demand, there will eventually be enough goods at that production station to fill each train, as they show up. This will take time of course, but I've been doing it and it works great. Its especiallly nice when you cannot or do not want to increase the size of your trains consist(Number of cars), to keep frequency up.

If your tracks are setup to go to two or more DIFFERENT places, then the supply station, will place enough goods on each line to try and full-fill the demands of each track. This will increase over time, and if the demand on each track is the same(rarely the case), you should see both lines getting evenly supplied. Remember, that the supplying station may take a few months to Ramp-up its production to meet the new demands of both tracks.
