Would it be possible to create a railway system which made use of the 
repulsive / attractive forces of (electro?) magnetism to cause the 
'train' to be suspended within a magnetic field and to travel along 
within it presumably unimpeded by friction? Sort of like this

NNNNNNNNNNN     <===  Magnetic 'cushion' above train

nnnnnnnnnnn     <===  top of train
sssssssssss     <===  bottom of train

SSSSSSSSSSS     <===  Magnetic 'cushion' below train
