I've added a bit about transport. The thing to point out is that these are isolated farming and mining villages. It's a bit Wild West in a way (did I mention Firefly? :) ) in that people tend to stay put - visitors arrive to make a living and moving about is possible but expensive and time-consuming to do. They do have modern communication with other settlements though. So going to Landing or a dozer arriving would not be unusual but still a big deal - like the paddle steamer arriving in a frontier town, for example.
