Colonization of the Moon
If multiple bases were established on the lunar surface, they could be linked together by permanent railway systems. Both conventional and magnetic levitation (Maglev) systems have been proposed for the transport lines. Mag-Lev systems are particularly attractive as there is no atmosphere on the surface to slow down the train, so the vehicles could achieve velocities comparable to aircraft on the Earth. One significant difference with lunar trains, however, is that the cars would need to be individually sealed and possess their own life support systems.
Technology in Star Wars
Levitation by these methods already exists in modern times, but with fundamental differences from "Star Wars", despite having the same output. An example of vehicles that maintain constant levitation without the use of constant propulsion is the Maglev train. The Maglev train stays afloat by using the magnetic repulsion of like charges, but relies on the surface that it travels above, in its case, the train tracks, to have the same charge as its own coils, resulting in a magnetic repulsion.
