That thing doesn’t weigh much compared to a real train with all of its cars attached.

Yeah it seems to me like it would be great for passenger trains but maybe not for 80 tons of iron ore and soy beans.

But do you really need your soy beans to levitate at 120 MPH? Maybe. I dunno.

The main issue it to be able to change tracks, which is not compatible with side-casters.

In the instagram post I stole this from someone mentioned that. Another person proposed having a wheel assembly that lowers in the event you need it.

Jesus Christ. Debby downer. It’s a cool concept.

I'm concerned about the effect this would have in the track.
This would have to generate heat, which is its own issue. But more concerning is the repeated powerful "polarization/ reverse polarization" cycle the passing EM field creates in the iron itself. I think that may lead to a type of fatigue that the rails may not be designed to withstand.

I'm an old fart... cassette tape could only be re-recorded with new music a few times before it started to lose its high end. The ferrite degraded from repeated use. That makes it easy to believe this floating train seem like it's going to need special track in huge amounts, really quick, for the same reason.

It's also down to earth video, not too flashy. If it works, I wonder if it's electrically efficient enough to reduce cost enough.
