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?

Plus, any maglev project has to be a new build and not outright replace existing lines. Replacing a line would require closing and removing the existing line, extensive reconstruction of the track bed, and probably delays or closure to tracks sharing the line. It's not an easy thing for the government to justify when it would be cheaper and easier to simply improve the existing rail infrastructure. Or..you know...ignore the problem which is what they seem to be doing anyways
