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.
Shanghai maglev train
The plan for the extension to Hangzhou was first approved by the central government in February 2006, with a planned date of completion in 2010. Work was suspended in 2008, owing to public protests over radiation fears
despite an environmental assessment by the Shanghai Academy of Environmental Sciences saying the line was safe and would not affect air and water quality, and noise pollution could be controlled.
According to China Daily, as reported on People's Daily Online 27 February 2009, the Shanghai municipal government was considering building the maglev line underground to allay the public's fear of electromagnetic pollution and the final decision on the maglev line had to be approved by the National Development and Reform commission.
