copperwire train track trick

I bet thats what the high speed secret underground trains use to travel
between military bases,well,some variant of the technology for sure.

Great find m8. 

I also thought that, though it might require to much copper to make such a giant coil, so like you said it has to be something similar.
Maybe electromagnets would be better though, cause then it's possible to reach much higher speed.

I do wonder how long the battery lasts, and if current is lost, does the battery even need to be charged?
Would love to experiment a little, but don't want to spend €30+ acquiring parts for something I have no use for, other then for this one experiment.
