Chinese researchers have successfully carried out a systematic test on a cutting-edge transportation system involving a high-speed maglev train running in a low vacuum pipeline in North China.
Given all the pictures of space craft in the background, I'm going to guess they're looking at this as a potential method of space launch, not intercity transport.
Not like that, you build a ~100 mile long vactrain into the side of a mountain, accelerate ~10 g for ~10 minutes, and then you only need a little delta v to circularize the orbit.

Space elevator in a vacuum tube? That's even sillier

Aaah, a mountain-sized space yeeter
