I'll show some of my work.Nature Gas Factory
Why not? Simutrans has 'Gas Tanke', but factory is not. why?
I made this.
(Graphic is from official oil field, gas station... someday, somebody make nice graphics?)
gasPlant provides Gas AND Oil. recently, I heard oil field provides oil and gas.
gasStation and gasModernStation consume gas. but gasModernStation can consume also Gasoline.
GasTanker is bonus. It can transport too much amount of gas. Yes, your freight terminal will be blown up.
Nature Gas is so light, and oil field provides so large amount of gas.
this fact is still remaining, 'I can't transport! TOOOOOOO MANY FREIGHTS!'.
