Hi all!

First i want to say thanks for OpenTTD, this is simply GREAT!

My problem is as follows:

Scenario:
1: I have a station lined up directly at a Steel Mill.
2: I have an Iron Ore Mill connected to the Steel Mill's station.
3: I Have a train with Steel wagons and Iron Ore wagons.

Now, when the train arrives at the iron ore mill, it collects the ore and goes to the Steel Mill with it. Then when it has delivered the iron ore, instantly the Steel Mill creates Steel on the station, but the train leaves without collecting it! It wants to collect it the next time it arrives, but before that happens most of the steel on the station is disappeared. So the train will never get the steel and the steel mill reports 0% transported.

THe only way i can get the train to collect the steel that is created is by selecting Full Load, but this won't work either because the train is the same that delivers the iron ore... So it will stand there waiting forever because the delivered iron ore will not produce enough Steel to fill the train.

This is the way it should work:

The train delivers the Iron Ore, and picks up the newly created Steel before et drives off again.

Thanks in advance

in the newest nightlies ( http://nightly.openttd.org ) there's an new option in the window of the trains orders (Full Load / Unload) called Transfer. This is just perfectly right for you

Try it;)

To install the nightly, Download it, and then switch your files with these are in the nightly.

Okay i will try that!

But i think this should be considered a bug?

The train needs to register and load cargo that are created on the station when it delivers a needed resource.

The problem is everywhere, like with goods too! If a train delivers grain and livestock to a factory, and the factory creates goods, and i have a goods wagon on the same train, then it does not pick up the created goods.

No, it's not a bug, the game know only load and unload, it doesn't know transfer command.
Try the nightly, the nightly is update for OpenTTD, and there's the transfer command.

Not a bug at all indeed... the order of events would be a bit like this:

train unloads
cargo accepted
train checks for cargo, none found
new cargo placed
train leaves

Not sure how efficient your train will be, considering that half of its wagons are empty all the time.

I solved this kind of problem as follows:
1. make train 1 car shorter than the station platform in both ends of the line.
2. add stations that have unloading and loading twice to orders list.

now, when the train arrives to unload iron ore, it runs all the way to end of station platform and unloads the iron ore. then it turns around and starts moving to get on it's next stop in orders list, in which it arrives after it has moved a length of car. Then it loads the steel and goes to where the steel should be going.

of course, if you are using "trains turn around in end of line only" difficulty setting, then you need to make sure that line ends on the stations.

Here's another way of doing it: Just build a depot behind the station. Order the train to enter the depot after unloading the ore, and then to go to the station again to load up the steel. The train will go to the station, enter and leave the depot, and stop at the station again. Works perfectly

Well another way I suppose is to make the train too long to fit on the station... the load / unload delay _might_ work.. I havent tested it tho.

or just use the transfer option....

I thought that the transfer feature was for feeder services . I can't think of a way to solve this problem with the transfer feature . Can you maybe explain it to me plz?

use: "transfer and wait for full load"

That won't work, because you then deliver the iron ore to the station for pickup by another vehicle (feeder service) and so the train will never fulload.
Problem with the fulload is too, that you never get 30 steel in return for 30 iron ore. So that system is also not waterthight.

okay, I'm sure I forgot to check on option:

"transfer and take cargo"

this will take all cargo whitout forcing it to wait to full load

That doesn't sound right to me.
He doesn't want to transfer the ironore he wants to unload it and then wait for the produced steel out this ore to take away, which won't be a full train load.
Why don't you build a station out of two parts, and let the train unload in the first and load in the second part.(without the full load of course)
It does work like this in ttdpatch :

[edit] ah that sound much better, but my solution works aswell[/edit]

Well in OpenTTD it will now message you like 'train xx has double orders'. Offcourse you can turn this of...

But are you sure the 'transfer and take cargo' option doesn't work properly for this situation? (haven't got a map now to test it.... working on a scenario ATM )

Tried it. But it doesn't work because I get the income in yellow numbers when the train arrives at the steel mill. So I don't really get the money from the iron ore. And the train leaves fully loaded with iron ore from the steel mill back to the iron ore mine. No steel is produced.

No steel is produced? Then there must be something wrong...
