Elon Musk says he won “verbal” government approval to build the world’s longest tunnel for an ultra-high-speed train line to connect New York to Washington.

The train, known as a hyperloop, would make the 220 mile connection in 29 minutes, Musk said in a post on Twitter Thursday. He provided few details, and a spokesperson for his new digging enterprise, called the Boring Company, declined to comment on the project.
