Saudi Arabia's Hyperloop would connect several cities in the Middle East, including Dubai, Riyadh, Jeddah, and Abu Dhabi.
The exact planned route of the line is still unclear, however. The company announced in late 2016 that it signed an agreement with Dubai Roads and Transport Authority to evaluate using the Hyperloop between Dubai and Abu Dhabi.
According to Virgin Hyperloop One, the system would travel two to three times faster than high-speed rail.
The company claims that it would travel at around 700 mph and take passengers from Dubai to Abu Dhabi in 12 minutes, which is normally a two-hour drive.
A trip from Riyadh to Jeddah — which currently takes over 10 hours — would last just 76 minutes. Going from Riyadh to Abu Dhabi — currently over 8.5 hours —would take 48 minutes.
Using a special type of motor, Hyperloop vehicles move by electric propulsion through a low-pressure tube.
Passengers would hail a pod using an app, which would list when the vehicle will arrive at the specified gate (similar to an airport).
Virgin Hyperloop One says there would be 120 pod gates accommodating over 8,500 passengers per hour.
Virgin Hyperloop One is trialing its system on its test track, called DevLoop, in Nevada, north of Las Vegas.
In July 2017, the team successfully tested a full-scale system on DevLoop. The vehicle reached a top speed of 70 mph, and the company hopes to reach 250 mph soon.
While cities have long used pneumatic tube systems to deliver small parcels, transporting people raises major engineering and cost challenges.
For example, to drive the pods through the tubes, it will require a very rapid air compression system, which would produce a lot of heat. Air-conditioning inside the tunnels would help with this, but that would require wider, more expensive tunnels.
Elon Musk is credited with popularizing the idea for a modern Hyperloop, and his tunneling startup (The Boring Company) is working on its own system.
In July 2017, Musk tweeted that he received "verbal governmental approval" for Boring Company to build an underground Hyperloop system connecting major cities in the northeast US.
The company is currently working on two projects in the Washington, DC region and Los Angeles. It first broke ground on a test site in LA in late 2017.
However, Boring is still billions of dollars and years away from building its first official tunnel. In LA, California's Environmental Quality Act regulates big construction projects, and Curbed reports that the review process alone could take at least three to four years.
Virgin Hyperloop One and the Saudi government believe that hyperloop transportation would stimulate economic growth, diversify the country's industries, nurture manufacturing and tech sectors, and spur job growth in the region.
"Today's visit and discussions kick off the next phase that will make Virgin Hyperloop One a reality in the Kingdom of Saudi Arabia," the company's CEO, Rob Lloyd, said in a statement published April 2.

Saudi Arabia and the UAE are exploring a number of futuristic transit options. In early 2018, Dubai began testing autonomous pods, which the city may use for local transportation in coming years.
