Elon Musk recently announced that he had received approval to build an underground Hyperloop, connecting New York, Philadelphia, Baltimore, and Washington, DC.
In 2016, just outside of Las Vegas, NV, Hyperloop One conducted the first propulsion test of their Hyperloop technology. Their goal is to eventually use the technology to build high-speed shuttles.
