the Trans-atlantic tunnel will be crossing the ocean under water and will be a magnetic force train going at speeds of so called 5000 miles an hour
IMPOSSIBLE but it really isn’t because they are building very big magnet that would be able to pu***hem 100 miles an hour faster on every magnet and they are only going to have 500 magnet to push it so that how it would go 500 mph
Any questions ask here
It will be going from east coast of the USA to west cost Europe
Show me the money![yeah]
I don’t think a tunnel is possible at least by today’s technology. The ocean is too deep and the amount of earthquakes due to the earths plates moving constantly, are enough to make it a challenge never mind finding the finances for it.
Yep, they are going to build a trans-Atlantic tunnel, right after they complete the Antarctic transcontinental line.
This is purely the realm of sci fi movies—It will never happen, how long did Bostons Big Dig take? how much did it cost? The logistic just are not feasable, Who’s done a geolocal survey of the deep ocean floor, no one! Ya see, theres a little thing called the mid-Atlantic ridge, basicly a 3000 mile long volcanic fault line, a spreading center where the tectonic plates of the Earth are pulled apart by magma welling up from the Earths core, kinda makes for a bit of a road block for any ideas like this. Also your at depth greater than the Titanics final resting place, monsterous water pressure.
5000 mph?, that sound like pure science fiction.
Finally, if a proposed highway tunnel here in L.A. is projected to cost 1 Billion $$ per mile, whos gonna pay for a 3000 mile tunnel?
All very well and good, but how will th epeople get back??
No problem, see that boxcar over there…yea… the one with the shackles…
Well, that kind of acceleration would certainly spill the coffee in the diner!
But, you might not even get thru the cafe car line to get your coffee before you reached the other terminal…
I think before we start figuring out how to get accross the Atlantic in 40 minutes, we ought to figure out how to run the Sunset Ltd. on time few times a month, first.
While I completely agree with what’s been said about financing such a project, on the technical side the proposals circulating lately (which are speculative, not actual blueprints) involve using floating tunnel tube sections rather than boring under the sea bed. I have read that (much,much) shorter tunnels are being planned using this method in the near future.
This is exceedingly unlikely to happen within the lifetimes of most on this board but, in the latter part of this Century, it is an intriguing possibility. If things such as molecular nanotechnology and self replicating, autonomous construction robots are someday developed, than who knows? Still I agree that we’re basically in scifi territory here…
Look up “A Trans-Atlantic Tunnel Hurrah!” by Harry Harrison…science-fiction novella from around 1975…
Nothing like a couple of hours zooming under the Atlantic followed by 24-96 hours in a decompression chamber…unless dying painfully is acceptable…
Submersed, floating pipeline segments are already being used on a much smaller scale for a natural gas pipeline across the Straits of Gibralter. It works well in this application because the gas is already compressed to a pressure higher than the ocean pressure at pipeline depth and the loading is static. Only the flow changes.
Now putting people in that equation will be very tricky - the tunnel will be much heavier to stand compression effects and the load will be highly dynamic - keeping stable floating at a constant depth difficult to control.

I suppose the answer to that would be submarine technology. If a such a tunnel would be constructed, the train would have to be pressurized as a submarine is under the water and subjected tons upon tons of pressure.
Thats nothin’ …look up the movie “Transatlantic Tunnel” circa 1936, British, very hard to find, but a hoot of an old sci-fi movie! [:0][:p][;)]
FOUND IT!!!

Found out what this topics origination was, namely a cable tv show. this is a nice “idea” but wont be built in this century unless there are some serious geo-political changes in the next few decades…also the idea of a vacuum tube under 3000 feet of ocean pressure sounds insane, one micro-leak and KABOOM, theres a Hell of an implosion along the entire route!

impossible
that will never happen in our lifetime
not to mention a really cool geyser at both ends…
The Tunnel will never work across the Atlantic.
There’s a little factor here that nobody’s considering. Granted I have the advantage of having ridden in the cabs of many trains going through tunnels and that gives me a little insight not available to theorists. As you approach the end of a tunnel you can see the vegetation along the tracks near the portal doing some really frantic moving. It seems that the train acts like a piston in the tunnel (cylinder). Now let’s extrapolate this to the European portal as a train is approaching after compressing 3000 miles of air. What is the velocity of the blast of air comming out of that tunnel ahead of the train? What is the temperature of the the front of the train? (ever put your hand on an air compressor after it’s been running a bit?) Another ship of speculation wrecked on the reef of reality!
I presume it will be “Open Access” no doubt, so we can get all that Montana wheat shipped over there?
