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?
Because it’s not currently profitable in most cases. Capitalism ensures that the merit of an idea comes secondary to it’s profitability. We don’t get the best things, we get the profitable things.
Where are all the maglev trains in non-capitalist countries? Sooner or later, in any system, someone has to do a cost benefit analysis and decide whether it’s worth it. It’s not just about profitability. There are plenty of situations in the US where something is unprofitable but still funded because the benefit is worth it.

Not to defend capitalism in general, but it’s really good at answering these sort of “is it worth the cost?” aquestions. The whole point is to allocate scarce resources efficiently; the problem is that it assumes nobody is a scumbag and all the costs are accounted for.

More likely just the shear cost of building the tracks.
They’re super expensive. Few people are willing to pay the massive amount extra for the slight dectease in travel time. Investors also know that.
Look at HS2 in Britain and how people are against the cost for higher speed options, or California HSR. I’m all for it, it should absolutely be done, but getting taxpayers to see 10 years into the future is difficult.
That’s because HS2 is a totally flawed, Ill thought out, over budget and badly managed boondoggle - just like everything in the UK rail system since the Beeching cuts in the 60’s. If it was properly run, well thought out - and actually made a significant difference in time (not approximately 15 minutes from Piccadilly to Euston), we’d support it.
You still need rubber wheels when it’s stopped and at low speed. They retract when it’s fast enough for the maglev to take over.
The electrical conductors are expensive as shit. The ones in the train need to be super cooled or something. The track ones need to be built along the entire length. On three sides, one vertically and two horizontally. Along with massive power lines along the whole length. They don’t need to move to be expensive.
The right of way needs to be very straight. So compared to normal high speed, you have to spend much more on buying land, earth moving, tunneling, etc.
All this needs to be maintained to an extremely high degree because you can’t accept a failure. The engine on a high speed rail fails and you just slow down, no biggie. HSR track is fairly robust and can easily be inspected visually. Since it has the same base as normal passenger and freight you have an entire industry knowledge and inspection machines. Any part of maglev fails and you have a catastrophic failure.
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.
