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.
Linimo
Linimo is owned and operated by and is the first commercial maglev in Japan to use the High Speed Surface Transport (HSST) type technology. It is also the world's first unmanned commercial urban maglev. There are some sources that ambiguously describe "unmanned" as "automated" or ignore the condition while making such a claim but Linimo was actually the fourth commercial urban maglev operated in the world, predated by the Birmingham Maglev (1984–1995), the Berlin M-Bahn (1989–1991) and the Shanghai Maglev (opened in 2004).
