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.
Tracked Hovercraft
Laithwaite was as publicly critical of the government's cancellation as he had been of BR's earlier efforts on LIM research. However, by this time he had distanced himself from the hovercraft arrangement, concluding that the maglev was a better solution. Laithwaite had found that careful arrangement of the LIM allowed a single motor to act as both the lift and traction system, a system he called "traverse-flux", or "river of magnetism". Having continued his research at Derby throughout, when it became clear that Tracked Hovercraft was truly dead, Laithwaite started pushing for the test track to be converted to a testbed for his maglev design. By that point Rohr, Inc. in the US were already experimenting with their own LIM arrangement of this sort on their ROMAG personal rapid transport system, and there were several German maglev efforts underway as well. In the end the TH test track was abandoned. Laithwaite's work would eventually be used as the basis for the Birmingham Maglev, the first operational maglev system.
