Thanks! Hopefully the setting will be clearer yet when I add symbols and railroads.

I'm really torn about the borders though. I want the colored style, but I can't get it to look right. I've made a couple more attempts but they aren't turning out any good. Either they become too colorful, or not steampunky enough. Three colors are too many, two are too boring. I'm considering doing something else entirely, like dotted lines, though I'm not really a fan of that kind of border for some reason. Does anyone have some other idea, or perhaps a suggestion for color combinations that would look better than what I've tried?
