If it is a train station, it also makes me think a lot of a loading crane.
How about a train station that has an inventory slot that can contain fuels and automatically loads the locomotive with it ?!?
That would be awesome (especially if done with a nice inserter-type animation) and it would most definitely make sense for a station to fuel the train.
It could also help a little in making train stations less cluttered.
In the early game you would have an inserter insert coal into the station (or do it manually in the very early game).
In the late game, you could imagine the station having a "requester chest"-type mechanic where you can set it up to automatically request coal from the logistics network.
I think we need this !
