Automatic train not working

[Spyderborg]

I tried to set up a basic railway to bring oil from the drill site to my base. Only one train and one railway. The train has a locomotive on either end facing opposite directions (since I read that auto trains will never reverse). I'm trying to set it up so that the train returns to the drill site once its tank has been emptied, and then return to my base once it's full:

In the screenshot the train is completely empty, so why doesn't it go back to the Sgtazza stations (the drill site)? It's not saying "no path", it just seems like the condition isn't being recognized.

Are your train stops rotated so the train can get them?
Trains won't reverse and they won't go past a stop to stop there unless there's some way to turn around.

Do you have any signals on the track?

I'm not really sure what you mean, the train stops are rotated so that the arrows are pointing in the direction that the train approaches on arrival. This also isn't a loop, it's a single rail with 2 dead ends and I want the train to go back and forth on it.

Nope. should I? I'm still a noob to this game

Your stops should be the right way then.
Signals are only useful if you have more than 1 train on a line ever.

Try setting it to "cargo inventory empty" instead of "fluid = 0"

I don't know why that would fix it but it's worth a shot, thats usually how I have my trains set up.

You didn't select the fluid type to be used in the comparision so this condition cannot possibly work* - either choose whichever fluid the train is supposed to carry (e.g. "crude oil = 0"), or change the condition to "inventory empty".

* Imagine a train carrying water and oil - how is the game supposed to know whether you want the train to wait until
1) oil is empty
2) water is empty
3) oil and water are empty
4) oil or water are empty
without you telling the game?

Nevermind I think I see what it is.

In the lower left of the GUI you need to select the type of fluid the train is evaluating as equal to 0.

I don't usually do fluid conditions but I would be willing to bet this could fix it!

Oh wow. That did it. Thanks everyone :D

You can also add "OR" inactivity or Wait for Time Passed as a failsafe so it doesn't get stuck at a station
