My own headcanon is that the kingdoms are connected by massive public transport systems of several layers, near the top being basically a hyperloop, and branching down into more normal subway systems within subcities. And you would have regular local hops across the country. Much of this is probably reasonably governmentally controlled, or at least on a single system.
