The Japanese have fitted an inductive pickup on one of their test maglev
trains, negating the need for an auxillary generator, but of course you
need to be moving for the induction to work, so batteries are still needed
for slow speed work.

What gets me is this proposal to build a maglev spur to Parramatta. The
train would barely make levitating speed before it would have to start
slowing down again!.
The maglev trains 'land' when running at slow speed, they don't sit there
bobing up and down on magnetic fields when stopped....
