Trans Atlantic train - Page 2

*Zion hops on the train* "Boy this will be fun!" *Train starts and picks up speed* "Weeeeee!" *Suddenly, Zion is pulled back through his seat flopping into the others as he is pulled to the back and then....CLANK!* "My bones...they hurt...oh so bad."

That is suck a waste of resources it makes my brain hurt. But it is cool. But it'd be easier to just fly a plane.

Maglev train underwater... not only would it cost so much to make, it'd take a helluva lot of power to make it work.

Wouldn't they like, have to pressurize the train?

The tunnel is in a vacuum, so yeah, the train is pressurized.

Its old man, they are planing to build one like it from UK to America.

actually it sounds like allot of money, but it is quite cheap. it's not just a passenger train, you can put cargo trains in there too, think about it. you can buy fresh food from other continents, all the ships carrying containers won't be needed, it's allot of resources saved, and much much faster.

as for "enourmous pressure". a person can go as deep as 90 meters. the limiting factor happens to be oxygen which becomes poisonous if it's relative pressure is over 2 atmospheres. if 300 ft is 100 meters, the pipes have to withstand 11 atmoshperes of pressure. one atmosphere is 1 k"g per square CM. so that's not too bad at all.

In concept it's great. In reality, it would never work. Imagine that thing sitting in the water 300 feet beneath the surface, for thousands of miles. The ocean currents would move it in all sorts of directions, navigational charts would have to be amended for submarines (that's just our government- I can see the naval pricetag now), the sheer resources and manpower alone would effectively cancel out any profit, only certain people can afford its price range for immediate to short-term usage (no profit), not to mention the damage to the ecosystem it would do (that's just in terms of aquatic life ramming into something that shouldn't be there, not to mention the new habitats it would create in locations that don't cater to that)... and what if you have problems?

Leaks? Pressure cracks? Do you really want to be the guy on that train when it springs a leak or develops stress fractures at locations? Ever seen that Stallone movie "Daylight"? How about the dude who has to go in there and fix it... halfway across the Atlantic, hurricane season, 300 feet beneath the surface, and OOPS! Here comes Murphy's Law.

As far as pressure goes... you can go deeper than 90 feet. I have.

unless its gonna be naturaly boyent, and float in one spot in the water itll need stilts, and if it doest float in one place, i can see alot of stress generated along it by the ocean, all over it, and held in two places on two different continents, and all of that small, but ammounting current pressure, itll snap in half.

pay attention, 90 meters. oxigen is 21% of the air you breath. that means it's normal relative pressure is 0.2 atmospheres. it becomes lethal at 2. so if at 1 atm (sea level) it's 0.2 atm you need 10 atm to bring it up to 2 atm of relative pressure. if every 10 meters of water have the same pressure as our entire atmosphere, you need 90 meters along with the atmosphere to make 10.

pay attention man, I'm a scuba diver too you know...

Rayder · 2004-03-29, 02:25 PM

Is it probable? No. Is it practical? No. Is it possible? No. Will it happen? No.]

It would cost too much to make, power, keep up, and is just plain stupid.

A Boeing-777 commericial airplane can reach top speeds of about 490 mph (789 kph). Not only is this cheaper, most people can afford it, and we already have it. No new things to make, no new planning. This is one of the stupidest ideas ever, making a maglev train across the Atlantic.

My bad. I saw "feet". Which is why my post said "90 feet".
