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.
High-speed rail in East Asia
The Shanghai Maglev Train, a turnkey Transrapid maglev project, imported from Germany, is capable of an operational speed of 430 km/h and of a top speed of 501 km/h. It has connected Shanghai and Pudong International Airport since March, 2004. In April 2007, China opened several high speed rail lines between major cities, providing a network of 6,003 km, making it the world's largest high speed rail network. By 2012, China will have a 110,000 km rail network. Of that amount 13,000 km will be high speed rail, some line capable of going over 350 km/h, making CRH the largest, fastest, most technologically advanced high speed rail system in the world. 
However, the Maglev line has suffered from low ridership, and various expansion plans (e.g. to Hangzhou) remain stalled.
