Looks pretty similar to the Japanese SCMaglev. But does that means the track would need to be active like the Japanese one? I tried to research this in the past and all the sources say that the Japanese Maglev has the linear induction motors on the track, in addition to passive coils that the train's electromagnets interact with.

That's in addition to Maglev's intrinsic need for power delivery coils in the track (the bottom of the track basically needs to be primary side of one giant very smart transformer).

Imagine building from Beijing to Shenzhen's distance in ultra high tech tracks that can't interop with regular trains, where they'll have to safely handle a 600 km/h train passing over them in the harshest weather conditions. And you can't have very thick armor for it because you need the magnetic fields to be as close as possible to make the power delivery efficient, It's both a construction and a maintenance nightmare. The tracks themselves will offset a lot of the ecological benefits of trains over flying.

SNCF set the wheeled train record at 500 km/h with a test train. Why not try to beat that?
