Tossing around some ideas for potential timetables one could make and wanted to know if this was possible.
These fuel stations are track-linked objects. So (without having tried!) I fear getting them in after the fact *might* be difficult. With some luck you should be able to bring the fuel station in only as a static mesh in a scenario scenery layer, then it would not really "work", but you could have the player stop at that location and act as if it was fueling.
