They currently have a 1.6 km (1 mi) track. Elon Musk indicates that they will have the 10-kilometer track by next year.
Virgin Hyperloop One and Saudi Arabia will build a 35-kilometer test track.
Virgin Hyperloop One has an agreement with Saudi Arabia's Economic City Authority. Together, they will carry out a study to build the longest test and certification hyperloop track (35km in length), and establish an R&D center and hyperloop manufacturing facility north of Jeddah, at King Abdullah Economic City.
A paper on the economic impact of the 'Hyperloop Centre of Excellence' will be prepared, and experts from King Abdullah University of Science and Technology will visit the Virgin Hyperloop One testing facility in Nevada in order to conduct a technical review and prepare a paper.
Hyperloop could enable transportation at nearly the speedo sound and improve connectivity across the Gulf, with a journey from Riyadh to port city Jeddah taking 76 minutes (compared with 10+ hours currently), and a journey from Riyadh to Abu Dhabi, UAE, taking 48 minutes (compared with 8.5+ hours currently).
