Correct me if you have a better source, but the information I can find 
suggests that the power for a maglev train is supplied to electromagnets 
in the track.

<https://science.howstuffworks.com/transport/engines-equipment/maglev-train.htm>

Which means **** all power is supplied to the train.

I have a memory of seeing one in the past where the train had a pair of 
contacts onto overhead wires, though I can't find it. But again, no 
power through induction.
