Whatever happened to those 600-mile-an-hour passenger tubes?

For years, hyperloop presentations promised the impossible-sounding commute: passenger pods gliding through low-pressure tubes at airline-like speeds, making long-distance travel feel like a brief subway ride. Beautiful renderings did much of the early traveling.

Hyperloop One became one of the most visible attempts to turn that pitch into something tangible. Backed by investors and, for a time, associated with Richard Branson's Virgin brand, the company built a test site outside Las Vegas and poured years into propulsion, pods and safety work.

On November 8, 2020, the company staged a real milestone: its first test carrying people. Two executives rode a pod around its Nevada test facility. Reporting on the run recorded a top speed of about 107 miles per hour—meaningful as an experimental demonstration, but a very different proposition from the glamorous intercity speed promised in marketing.

The company later shifted its emphasis from transporting passengers to moving freight. In December 2023, Bloomberg reported that Hyperloop One was closing, selling assets and laying off its remaining staff after attracting more than $450 million in funding since its founding, according to PitchBook figures cited in the report.

The important distinction is between the end of one company and the entire transportation concept. Hyperloop One's shutdown did not conclusively settle whether future tube-based systems can work. It did settle what became of this particularly famous commercial attempt.

The pods made it down the test track. A paying passenger network never followed. If history needs a ticket stub, this one has only a test-ride receipt.
