Why are maglev trains still rare? (lemmy.ml)

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?

Plane maglev tracks are way more expensive than wheeled train tracks. It's slower to get expensive when the terrain stops being plane, but it takes a lot of roughness for it to become cheaper. Most countries just do without trains crossing rough terrain.

And the largest cost of almost any train is the tracks.
