The first images of a Hyperloop test track built in the middle of the Nevada desert have been released.
It was designed by California company Hyperloop One, who has unveiled ambitious plans to transport people or cargo between cities at near-supersonic speed.
The 500 metre-long Hyperloop test structure, which has a diameter of 3.3 metres, is located around 30 minutes from Las Vegas.
Hyperloop One announced in November an agreement with Dubai to evaluate the construction a 500mph train they hope will be capable of travelling to the neighbouring UAE city of Abu Dhabi in just 12 minutes.
