PayPal, Tesla and Space X don't have to deal with environmental impact studies and NIMBY's.

A supersonic train? Not gonna happen! Imagine the sonic boom at ground level !

Crank up the DCS and Legacy/TMCC speakers!

The only infrastructure I could see that could support such a train would be running a mag-lev inside a concrete and steel tube. The air displacement shock wave that normally creates a sonic boom wouldn't be above ground, but God knows how they'll manage the air flow in the tubes.

Pods 2 meters in diameter?  Definitely NOT designed for claustrophobics!  I had an MRI a while ago and that was bad enough!

Let's skip this step and advance directly to molecular transport.  "Beam me to San Diego, Elon."

Ahh, But Science Fiction already answered the problem with the fix: The tube is held in near vacuum, the train airlocked in and out at the ends.

Speed is not limited by airflow that way.

Of course, the Sci-Fi propulsion method (Pre Mag-Lev) was a literal blast. Add some methane behind the train and ignite, Boom, lots of acceleration.  A bit rough on passengers tho.

Fun to watch for sure.

I always think of the last 'transportation revolution' called the Segway....flop but for mall cops.

Segways are a tourist ride here in a couple places too.

Will 'hyperloop' super-train really link San Francisco and LA in 30 MINUTES?

 Last time that I had an MRI. I shouted out 'Torpedo los!' when they closed the hatch. I then had to wait until the technicians had stopped laughing before they could start the scan. I was also told that I was a sick puppy. But I knew that already. 

What I wanna know is, just what kind of "magnetic-levitation" do conventional bullet trains use?

I saw this type of thing on an episode of SeaQuest DSV.  It didn't end well...

Luckily for all you naysayers,there are dreamers and every so often successes

Remember at one time everyone thought the horse was the best way to haul things around, the railroads were a gimmick and if you traveled above 20 miles an hours the air would be drawn from your lungs
