There are none.  What about the air above the Atlantic at the moment...a good wall?

It's the reassuring distance that counts.

You seriously think that would not be taken into consideration and that they need a couple of Asean Now posters to point out the snags?   Has construction not taken place on existing seismically-active areas?

Across an active spreading plate margin, no not many, but Iceland sits on that same plate margin, it's the reason the island exists, and their roads get cut off and need rerouting after major events.

Well what about the ocean? Thats wet and tunnels leak. Long way for the Flex Seal guy to travel with the can.

Traveling at 3,000 miles per hour? 

Atmospheric pressure beneath the bottom of the Atlantic?

So, sounds like they'd need a solid, pressurized environment.  Like the one that popped when those people went to see the remains of the Titanic?

What would be the 'G' forces on passengers during the acceleration/deceleration phases and the time of those phases?

As long as the travel is straight (no curves or gradients) then a steady increase increase in velocity would be okay. Don't forget the 'force of gravity' is downtowards the Earth's center. The slightest curve however would invoke the centripital/centrifugal/'g force'. Say 5000kim/h is about 1389m/s. a circle radius of 30km would still result in about 64g, enough to kill a human. Now that's for an aircraft and how tight a curve it could make but for a vactrain under water I don't know how that would modify the equations. Perhaps an engineer member here could work that out.

Yes because we are "idiots" and enjoy life. 

So do people who have had prefrontal lobotomies.

You have to count in the immigration lines... but why go from 1 hellhole to another?

If it's Musk's Millions then I don't care.  Zero tax dollars/pounds please.

It could be funded by the gold that will soon go missing from Fort Knox...

 

At least it does demonstrate the dangers of ketamine consumption.

Call it the Transamerican Tunnel and Trump will be all-in.

 

Drop the trans and just call it the American tunnel. Trans and America are incompatible.

On the city - Shanghai airport trip there was some limited feeling of speed but nothing serious. Faster, who knows?
