Maglev for Scotrail? However will we get a model of this if it goes ahead? Will this be the shape of things to come? If it does, then does this mean that model rail could go from three rail to two rail to no rails at all? How would we power a maglev model?
Judging by all the other BBC articles about councils 'considering' maglev trains I think it is more a case of 'dreaming' than 'considering'... Maglev is completely separate from conventional rail in not only technology but infrastructure and really is as irrelevant as aircraft I think. At £2bn I would love to know where the money is coming from...the sad truth is that domestic flights between the two cities are more practical and cheaper if we ignore environmental impact, as most people will continue to do.
A maglev model is a challenge - one could use air jets but this would require some kind of generator and be noisy and probably bulky, and of course regular holes in the track/runway. Induction could transfer power to the maglev model from under the runway to power lights on the model, but using maglev technology in minaturised form is a very long way off in the future I think. A simple superconductor and magnets on the maglev model is not practical because you need liquid nitrogen/hydrogen/helium depending upon the superconductor temperature. One day supeconductors may get up towards room temperature and then they become very useful...until then impossible for modellers!
I guess the best method is to cheat and use concealed wheels underneath - as the sides of the maglev curve around the track they would be concealed from the side and so not obvious to an observer. The runway-maglev gap distance is very small anyway so this would be easy to pull off, just look at the picture above - there could be wheels on the Shanghai one and you wouldn't know...
...apart from the smell of burning!
Scale speed of 500 km/h in 1:160 scale is 87cm/s - probably possible though!
