NY-DC in 29 mins.— Elon Musk (@elonmusk) July 20, 2017A Miami-Orlando route is one of 11 proposed finalists vying to compete for the rights to build the ultra-fast transportation system in the U.S. The 257-mile route normally takes about 3 hours by car, but would reduce travel time to about 26 minutes, the company says.Hyperloop transportation uses a magnetically-levitated train inside of a low-pressure tube, giving the train the ability to potentially travel as fast as an airplane.On an average day, a car ride from New York City to Washington D.C. takes just more than four hours and about 3 hours by train. The Hyperloop would take 29 minutes, according to Musk.
