Los Angeles-based startup Hyperloop One has made it its mission to build a rail system that levitates pods on magnetic skis and sends them through a low-pressure tube at 760mph. At a railway priming in Dubai on Tuesday, the startup showed the first images of the test track it has started towers in southern Nevada, north of Las Vegas.

The test track is going to be 500m (or well-nigh a third of a mile) long and 3.3m (almost 11ft) wide. A printing release from the startup said that it hopes to do a public test in the track in the first half of 2017.

Hyperloop One demonstrated its propulsion system at the Nevada site at a printing event last May, where it sent a 10ft sled 116mph on some open-air tracks until the sled hit some sand and slowed down. But since that May printing event, the visitor has faced a number of scandals and lawsuits that ended in several senior members of the company, including lead engineer Brogan BamBrogan, leaving the company.
