I think there's an issue in compability with Space Exploration mod because after building space elevator my trains won't go to Fuel Station (name is set on default and I literally coppied it from settings menu) no matter how low on fuel they are.
If you would like to see what happening I can provide logs (if need) or if you dont I dont mind, as you said this mod was uploaded for your multiplayer session, just will look for another mod.

Hey SirRogro, I don't really have the time to try to make it compatible with other mods. I would look at https://mods.factorio.com/mod/FuelTrainStop which is probably a better version of my mod anyway! I feel like there was another one I saw a few months ago (and was even thinking of trying it the next time I boot up Factorio, which I haven't gotten around to in a while), but now I can't find it... or it may have been the Fuel Train Stop one.

Hey SirRogro, I don't really have the time

Understandable..)

I would look at https://mods.factorio.com/mod/FuelTrainStop

Thx! Will look. Already checked "Train Control Signals" but it needs station to be put in shedule manualy and it gonna be pain to start use it now, when I have 200+ trains already T_T
