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.
Lathen train collision
The Lathen train collision occurred on 22 September 2006 when a Transrapid magnetic levitation (or "maglev") train collided with a maintenance vehicle near Lathen, Germany, killing 23 people. It was the first fatal accident involving a maglev train.
