Musk said there would also be "up to a dozen or more entry/exit elevators in each city", referring to both D.C. and New York City. Philadelphia officials denied that they had had any contact with Musk or a representative from his companies, as did officials from the state of Pennsylvania, the New York City mayor's office and the New York state Department of Transportation. He wrote later that he still had a lot of work to do on formal approval.
When completed, Musk said the system would include stops in Baltimore and Philadelphia. "We do not (know) what he means when he says he received 'verbal government approval, '" said Mike Dunn, spokesperson for the Kenney administration.
Musk isn't willing to stop with NY and D.C. The billionaire entrepreneur continued to tease his plans on Twitter, replying to another user asking about a potential hyperloop system in Texas.
Elon Musk says he has 'verbal' okay to build multi-state underground Hyperloop
As organizations like Hyperloop One propose potential routes for their high-tech, high-speed transportation pipelines, Elon Musk's own The Boring Company (yes, it's really called that) looks to have the go-ahead for an experimental track of its own.
Like many of Elon Musk's ideas, the Hyperloop high-speed rail system seems straight out of science fiction. "Makes a big difference if they hear from you".
Musk and the company have touted the possibility of untrafast travel via hyperloop system for years.
