(This has more details than the brief account in today's (12.viii.2013) New York Times. Elon Musk-- an entrepreneur with successes in computer software behind him-- is proposing a super high speed train (San Francisco to Los Angeles in half an hour). Track to be inside an elevated tube (it would HAVE to be enclosed: you don't want to generate sonic booms by running supersonic trains in the open!) The proposal has been met, if the NY Times can be believed, with some scepticism: the projected cost seems unrealistically low to many.)
