#Need help on how to make the train run on a curtain condition.

What I would do is set the train to leave "Oil" when cargo is full and then leave "Boilers" when cargo is empty.
It does mean it will idle at boilers most of the time though.

It's a bit more complicated and requires circuitry if you want it to wait at "Oil".

The train would only leave "Boilers" to get more fuel when it's empty.

#

In the long run, the train wouldn't transport more fuel than "Boilers" consumes. You might want to reduce buffer space to reduce the amount of fuel lying around though.

Alright, the complicated way it is.
You'll want to set the same schedule as above to the train.
connect all the chests on the boiler station together with circuit wire and into the input of a decider. Then set decider to [solid fuel] < (how much you want to buffer), output L
Connect the output of the the decider to the station.
In the station change it's settings to "set train limit" and ensure the input signal for the limit is [L]

btw this goes into the "Boilers" station
edit: I see it's part of the screenshot :)

ah yes. no need to do anything on the Oil station

You didn't specify not to use chests. Can you give more context around your problem and what you want to achieve?

# edgy finch Why chests...

You can swap into reading belts instead, but you may run into issues of the train not arriving fast enough.
If you wish to do that, connect the input of the decider to a belt instead and configure the belt to read contents, and hold.
Then make sure the decider condition is 1-8 as 8 is the maximum a single belt can hold

I hate this game...

I'd put a chest for each boiler and limit it to a few stacks.

#

This is a really small buffer and hard to make sure the train arrives in time.

You do realize that if you're burning solid fuel in boilers, there's half a minute of buffer, at best, in the boilers, right?
And that track is going to take longer than 30 seconds to do a loop in

If you don't want the boiler setup to change, Novas initial suggestion isn't much different from your request.

#

Without buffer it's practically the same.

this.
if you want to minimize buffer, limit the cargo wagon to a stack or two

#

though you'll waste a lot of fuel with the train going around mostly empty so that's of questionable benefit

lethal veldt
#

Yeah, a chest between each boiler and the wagon, limited to 1 stack, would provide enough buffer for the train to not go around like mad.

#

Could still use a circuit condition then, to reduce buffer even further.

#

And keep the wagon at a couple stacks to keep buffer reasonable small.

Personally I swapped into chestless stations few months back.
And the only way they work(ish) is by having a train unloading, always.
And how they work better than chest stations, in my opinion, is when I have dual stations that are circuit controlled to flip flop which station is unloading. But it's still a train always unloading, or attempting to unload.
