Ok, this is probably a stupid question.
I'm trying to have a national wonder increase a civ's movement rate on railroads.
I know how to do this with technologies, but that doesn't really work well for our mod. We would rather do it with buildings, if possible.
Unfortunately, I can't figure out how to do this. If anyone knows, it will save me a lot of hair pulling if you could post details.
Thanks in advance.
