Two Questions:: Mid/Late Fuel Sources and Automated Fuel Station

[Pie]

I have a Greenhouse style solution to wood for the middle of the map. But no matter what I do, I cannot get a good amount of wood out of it. Even if I scale it up. I get a lot of stuff pulsing on and off. (I fear that I'm expected to make a massive parallel train track across the whole map. Which seems wholly ineffecient.)

Secondly, does anyone have a good solution to trains going for fuel. Currently my trains are set in parallel. If they pass a train station, they go in until they're full up. (Checked via sensor.) But I'd prefer them to only go in if the train really needs it. Rather than say, already 90% full.

The trains usually run a very long time with coal , my trains runs a circle around the whole map ( but multiple trains on the same track ) and I think just a bit coal is enough to have enough power for the whole circle

Also about using alternative ressources : I also like to do a Greenhouse Loop with Leaf Knots, but like 4x the Loop , so all the Leaf knots which aren't needed will be used as fuel
-> Still , coal is better, but there will be other recipes to create normal wood, too. Then you can use this wood to create Coal , which works better :)

About the Train Fuel - topic :

I usually let them stay in the train station for 10 seconds. In this time a hauling spark is quickly moving on 2-path-tiles and filling up the train wagon with items it pulls out of a small crate ( or big crate ). For me personally the 10 seconds are enough, since the sparks don't have to walk a long way to get the items/fuel to put it into the train

Hope this helps !

It's unfortunate you can't test things like train fuel status at a junction.

I started with the timed solution, but these days I use logic circuits. Any station that loads fuel won't let a train leave unless it has at least 20 coal on board. Typically this is the station that loads the cargo, but sometimes it's the destination station that has fuel.

I.e. Leave Station if cargo full AND at least 20 fuel on board. Or Leave Station if local storage full after unloading, AND the train has at least 20 fuel.

A train goes a *long* way on 20 coal. I'm pretty sure it could circle the map on that much.
