Back when I was going to do stuff in South Finland, I think Aaron described it as being in a similar state to its northern parts and the Communes. It's probably doing much better than those two, but it's likely it still bares the scars of war, with buildings still being repaired, crumbled, ect. It's likely carriages are a thing but probably not the main source of transportation since they would get access to resources that the Communes and North Finland don't have plenty of, like oil.
