Thanks for the mod, I like it. I especially like that it is as simple as plopping one down and trains will automatically add and remove the stop as they need it.
I don't know if you've noticed, but there's a typo in the mod title. It says "Staiton" instead of "Station".
Aside from that, I'd suggest using "stop" just so it is the same throughout your entire mod (title/content) and vanilla base.
Heck, as awesome as this works I'd name the title something like "Automatic Train Fuel Stop". Then name the in-game item simply "Train Fuel Stop". :)
