A train with a wait condition of "5 seconds of inactivity" will leave the station while the locomotive is not fully refueled.

A combination of a small cargo load (e.g. depleted oil wells), a long trip, and burner inserters for refueling can lead to a train using more fuel per trip than is loaded.

This sounds as if the train is doing exactly what you told it to do, why not use a when full condition or what ever is available and better suited. Or am I misunderstanding you?
If I did, upload the save please.

It seems to me that all the conditions relate only to the cargo wagons on a train, and none to the locomotive fuel status. Maybe this is by design, but I was hoping that inactivity, at least, would consider fuel loading into locomotives too.

While it may be possible to come up with a circuit that can detect this, but it seems far from trivial.

Maybe there should be a dedicated condition to force waiting until fuel is full?

Fixed for 0.13.6.
