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?

There are some concepts for hybrid maglev-rail tracks that would at least solve the first point, similar to how rail was electrified over time. It would still be very expensive though.

woah this is awesome!

maglevs need classical wheel systems anyway because there might be a power outage, so simply having wheels that are compatible with the local rail system is a brilliant idea.

add in a tiny propulsion system so they can use the normal tracks at low speed without the help of the maglev tracks and you can sort of blend the two systems together in critical locations like switches and train stations.
