The more research I do on trains of the future, the more times I come up with schemes from the past that are essentially the hyper-loop idea.
Here is some text translated from a Spanish retro-future site:
But the most phenomenal media would be underground and underwater. There was a detailed project of Robert Salter, the Rand Corporation, to connect the two coasts of the United States with a system of tunnels under vacuum called Planetran. Salter in the scheme, originally formulated in 1957, a number of electromagnetically suspended wagons would be accelerated in the tunnel up to 22,400 kilometers per hour, so that passengers would sit on armchairs turn forwards during acceleration, and addressed to 'back during deceleration. On arrival and departure, they felt a boost of 40% of the force of gravity. For maximum acceleration and deceleration, the drive would reach 1 "g". expected time, 21 minutes from New York to Los Angeles without intermediate stops. "The Planetran not require any scientific progress" argued Salter. "The critical points are the tunnel alignment, control of the vehicle and the tunnel excavation itself. The technology for these and other areas of the Planetran development already exists." The tunnel, concrete, plastic coated, it would not be right but was obviously followed the curvature of the earth, diverting the path of up to 800 kilometers. In case of emergency, gigantic air bag would be inflated to block the section of the train, which would have been filled breathable air.
