Not sure if this is new in .16. I have seen it in 16.0 and newer. I have a feeling I just never tried it in older releases.

If a train is out of fuel and also in auto-mode, inserters won't load anything (including fuel) into it. Easy to hit when placing new trains if you place the train but don't have fuel chests placed yet. I also had it happen once when a train rolled into a station while out of fuel. Coasting a train into station with absolutely zero fuel has to be pretty rare though.

Steps to reproduce:

1. Place a locomotive on tracks.
2. Set a schedule, any at all will do.
3. Put the train into auto-mode. (it won't go anywhere, it doesn't have fuel yet)
4. Place a chest with some fuel (any kind), and an inserter. (Bug) The inserter won't activate to put fuel into the locomotive. Cargo wagons won't load either.

Workaround: toggle the train into manual mode, the inserters will wake up and do their job.

Trains are not accessible to inserters in automatic mode unless they are stopped at a station.

They really should be. Every other item in the game loads and unloads regardless of state with inserters, this was behavior I did not expect and ended up googling around to figure out why my inserter arm wasn't putting fuel in to my out-of-gas train.

You really don't want them to do that. If they did, any time you had a train drive through any station it wasn't trying to stop at it would start having items added/removed from it as it waited at signals.

I see what you're saying. Perhaps they should only put (fuel) things IN to stopped engines, then.
