The first tests of Elon Musk's revolutionary high-speed transport system could begin soon after Hyperloop One, one of 12 companies competing to make the idea a reality, completed its test track.

The company has finished work on its 500 metre long testing tunnel, which is situated in the Nevada desert, near Las Vegas, and has a diametre of 3.3 metres. It is expected to run initial trials on the near-supersonic speed train in the first half of this year.

Hyperloop One announced the news alongside 11 proposed routes for the super-fast transport, all of which are in the US. The longest proposed route is 1,152 miles from Cheyenne to Houston and the shortest 64 miles from Boston to Providence.
