I see a lot of train games at Origins. They're all different, but they're all sort of the same. Each player has a company. In some games you can buy stock in each other's company, or players own parts of various non-player companies. Lots of games. Anyway, they lay track and move goods to market.

(I don't know much about train games because if I don't get to blow up the train as it goes over the River Kwai, I don't really care.)

So maybe for the Star Fleet Universe, we need "pre-surveyed high speed freighter routes" as the equivalent of tracks? Beyond that, I leave it to someone who actually knows train games.
