Hyperloop One claims that its prototype ultra-fast train has completed a first full systems test in a vacuum, reaching a speed of 70 mph. The sled was able to magnetically levitate on the track for 5.3 seconds and “reached nearly 2Gs of acceleration,” according to the company.
The test was conducted privately but Hyperloop One offered some video that included footage from testing. Based on that footage plus a few seconds of additional b-roll shared with media, a lightweight skeleton sled uses a linear motor to accelerate, levitates briefly, and then comes to a halt as the brakes are applied.
Hyperloop One was created as an answer to a challenge from Tesla and SpaceX CEO Elon Musk, who wrote a white paper envisioning a mode of transportation that would send pods at speeds greater than 700mph using a low-friction environment and levitation using air bearings.

The thing that a lot of people miss is that you don't even need a complete collapse of a section to be fatal to anybody in the tube at the time. All it needs is to dent enough that the capsule catches on the dent in order to be a catastrophic failure that would destroy a portion of the tube, the capsule and anybody in it.

I guess that depends on how close the capsule is to the shell of the tube. But if it's not close, then you'll need a huge dent. Events that make huge dents are easy to detect. Huge dents are easy to detect as well.
