A futuristic transport project that will see passengers propelled at near-supersonic speeds has declared its first successful test.

Hyperloop One, the brainchild of Elon Musk, said it made a vehicle travel at 70mph for five seconds through the Nevada desert using magnetic levitation.

The company’s next goal is to ramp the speed up to 250mph, before aiming for 750mph.

It has also created a prototype pod designed to carry people or cargo through the low-pressure tunnel on a cushion of air.
