I don’t like the idea of wheels, nowhere is flat enough to use them at a reasonable speed. A mag lev rail system would be wonderful, especially underground for mining where ships can’t go easily. My only concern is the construct system, the space elevators that have been built us 30 L cores minimum to get up to 6KM so to build a working large rail system, even if your own area would take quite a few L size cores all arranged perfectly to make sure buildings lien up.
i have seen some nice systems using small ships with hover engines surrounded by a static structure however they didn’t seem practical except for space elevators.
