Above Ground Train running out of fuel

I'm trying out this mod and the spawned in train will just suddenly die within a couple of minutes use.  I have "useFuel": false in my config.  Any ideas what would cause the train to just stop?  I cant loot/add fuel to to the trains.

Do you have any other plugins which could affect fuel consumption? You can search the code of all your plugins for the keyword maxFuelPerSec to narrow it down to the most likely plugins.
