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.
List of maglev train proposals
London – Glasgow: A maglev line was proposed in the United Kingdom from London to Glasgow via Birmingham, Manchester, Leeds, Newcastle and Edinburgh with spurs to Heathrow Airport and Liverpool. It was rejected by the Government in 2007 and the company behind it ceased promotion of the scheme in early 2013.
