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?

If you introduce a new rail type into your rail network you can’t use your existing fleet of trains on that section reducing the ROI on that train engine or carriage. Also, any train you purchase for the new rail type will only ever work on that system lowering their profitability in the long term.
Also the fact that ‘less moving parts’ doesn’t mean lower complexity or maintenance cost. Train wheels are a very robust and efficienct mechanism and most train designs are not being limited by them.
Very robust because they have 300 years of research, innovation, materials science and manufacturing in them. Making them incredibly stellar, well understood, damn near perfect technology for what they do.
