http://www.smartplanet.com/blog/intelligent-energy/new-york-to-london-in-an-hour-by-train/16456?tag=nl.e550You could call it a pipe dream.
That’s how the BBC refers to it on its website, where a feature story reports that one day soon, trains traveling through vacuum tunnels could whisk passengers from New York to London in an hour, hitting speeds of up 2,500 mph.
Reverse the journey, and you could leave the UK at noon and arrive in Manhattan at 8 a.m. the same day.
The key is in the vacuum. Suck the air out of a transatlantic tunnel, and you eliminate resistance to the vehicle. In the oceanic version, engineers would tether the tunnel at a fixed depth.
The “vactrain†is not a new concept. Robert Goddard, who created the first liquid fuel rocket, designed a prototype over 100 years ago, with the idea of zipping people around between U.S. cities. But they haven’t been economically feasible, or even fast enough.
Traveling in emptiness: Rendition of travelers in an evacuated tube hurtling through open country.
Now, the latest concept in vactrains could make the difference. It combines the technology with magnetic levitation, in theory supporting speeds of up to 2500 mph according to the BBC. That’s an order of magnitude faster than today’s high speed rail, which tends to travel at just under 200 mph.

So it literally IS a pipe dream?

That would be cool. I can imagine in hundreds of years being able to travel anywhere in the world like this and go all over the planet in one day

And what if you were DREAMING while inside the PIPE? :O

This is impossable because nothing travels faster than the speed of light

New York City to London distance is 3461 Miles.
So they will have to hit the throttle and push the capsule over 2500 MPH. Child's play.

Which is over the speed of light, also the tube wouldn't be straght or "as the crow flys" so the distance is actually longer. Child's play.

Speed of light 186,282 miles per second. I cannot find a single reason why the tube cannot be straight. I can see why it cannot be straght.

But we don't know this for sure and light canNOT turn corners without slowing down! Also no tube going the distance from London to New York is going to be straght, that is commen sence.

Deflection will get you nowhere. Light speed does not enter into Topic: New York to London in an hour - by train Pipe dream?
"commen sence" = No compute. The tube will be straight when compared to a Megaparsec. Because of minor variations, the conductor will just have to push the throttle just a little harder to compensate.

2,500mph is not over the speed of light, lol.

2,500 miles per HOUR > 186,000 miles per SECOND.
DERP!
