They were invented decades ago.

They have fewer moving parts than wheelbois.

They require less maintenance.

There's obviously some bottleneck in expanding maglev technology, but what is it?

The ones in the train need to be super cooled or something

maglevs arent using fuckin superconducters to levitate, it's basic magnetic repulsion. Get whatever fictional version you've got in your head cleared up.
