CMStPnP They reported in the hyperloop tests as well as some of the maglev tests that above a specific speed some humans feel physical discomfort, disorientation or dizziness.
There may be a subsonic vibration at certain speeds. That's been encountered with ventilation systems. Above a certain speed even slight undulations in the carriage system may induce that.
Larry Resident Microferroequinologist (at least at my house) Everyone goes home; Safety begins with you My Opinion. Standard Disclaimers Apply. No Expiration Date Come ride the rails with me! There's one thing about humility - the moment you think you've got it, you've lost it...
BaltACDWhen they get the speed up to 300 KPH for 100 KM or more, then they will have something to crow about and build upon.
Cost to build and maintain has to be proven as well. As well as capacity to haul large amounts of people on a per hour basis. I have a distinct feeling the theory will fall apart in one of those areas. We shall see.
There is also a speed limit that has not been mentioned so far. They reported in the hyperloop tests as well as some of the maglev tests that above a specific speed some humans feel physical discomfort, disorientation or dizziness. Forget what speed that is but they hit it with the Maglev in China and I am not sure how they fixed it or if they fixed it. Virgin has run into it with it's slower speed tests.
Gramp I think construction of Japan's maglev has been stopped for now. I think these technologies are like the SST. Exciting but only 'useful' til the money runs out. What's the point when you can reliably fly 600mph by air and 180mph by rail? Personally, I'd rather resources be used constructing the safest possible, most reliable, economical electrical system. And a safe, efficient hydrogen fuel cell system for road vehicles.

600 MPH by air? In which century?
Airliners fly much slower than that to save on fuel.
If GM "killed the electric car", what am I doing standing next to an EV-1, a half a block from the WSOR tracks?
If I wanted to ride in a transonic Suburban with tiny porthole windows, I'll do it well above the ground with a good BRS/parafoil emergency mechanism, not in a trillion-dollar single-purpose tunnel that even minor earthquakes might compromise. This is Beach's vacuum subway 2.0, with roughly comparable throughput, with either remarkably long safe headway or effective 'platooning' with physical contact (considering the effective deceleration should a pad 'lose integrity' on one of the Suburbans...)
If the whole generation of Aerotrains failed to thrive because there were no alternate uses for the track, and no cost-effective primary uses for the track ... why should we think a system with 3x the guideway cost and only a fraction of the operating safety would be any better?
MagLev is much further along than Hyperloop. I expect to see the infant phase of an intercity MagLev system break ground within this decade. Either in China or Japan. Hyperloop is many decades off from any feasible operation. That's if it does become feasible.
How many 'tubes' will the Hyper-loop vehicles operate in each direction - what sort of headway will be maintained between vehicles? Questions? Questions? Questions?
There is a long, long, long way between 'proof of concept' to a operating system with a positive economic return on investment - be that investment public or private.
Never too old to have a happy childhood!
Monorail! Monorail!
What problems with "duo-rail" ground transport are these systems supposed to solve?
Has hovertrain or maglev ever offered any advantage with respect the maintenance cost of both the tracks and wheels and bogies for high-speed trains? Or is the maglev advantage speed, and the Hyperloop, yet even more speed?
How do you make a switch with Hyperloop, or is the idea that one would get out of your seat and board a different Hyperloop at hub stations?
The "build out" to make such a system actually useful, might prove daunting.
Oh joy, another form of mass transit competing for subsidies.
