How does this work? Does it require special train stop names?

You have a special train stop. It is also possible to build several of them. Once you rename one, all other stations will also be renamed.

What name should the train station have ?, Do you have to put the name of the station in the train ?

Sorry for my English, I am french

Quel nom dois avoir la station de train ?, faut t'il ajouter la station dans le trajet du train ?

The stop must have no special name. You do not have to put anything on the trains.

This mod is great but not intuitive. If anyone is wondering, this is what you have to do:

1) Build a normal train network
2) Set your train schedule normally
3) Craft the Fuel Station item
4) Place it on your rail network
5) Setup something that would insert fuel in a train that is stopped there
6) Wait ! When the train is low on fuel, it will automatically search for the nearest fuel station, go there and resume its schedule when it's fulled.

I think this is one of the mods i will use every game from now on.

how does this work with different size trains? Ex. 3-15-3 or 1-1-1?
