Could an Undersea Hyperloop Train Tunnel Offer One-Hour Trips From London to New York?

'Proposals for a tunnel connecting the U.K. to the U.S. underneath the Atlantic Ocean have resurfaced,' reports Newsweek, 'but with a price tag of almost $20 trillion, the project is a big ask.'

With the two global cities being over 3,000 miles apart, construction would take several years — the 23.5-mile Channel Tunnel linking England and France took six years to construct — and require significant investment. Estimates over the cost have reached as high as £15.5 trillion, the equivalent of $19.8 trillion.

However, developments in vacuum tube technology have made the concept more viable. By creating a vacuum within the tunnel and using pressurized vehicles, trains traveling along the structure could theoretically reach speeds of more than 3,000 mph, making the journey between London and New York barely an hour long. This is because trains would not face any air resistance within the tunnel, allowing them to reach higher speeds than unconventional trains. This design, which has seen new development in Indian transportation, is sometimes called a 'hyperloop'. Cutting the intercontinental journey down to a matter of minutes means that for the first time, the Transatlantic Tunnel justifies the hefty price tag that undersea construction comes with, as it would become significantly more efficient and environmentally friendly than flying.


While no plans are underway, it's interesting to ask whether it could even be done. Weighing in, Elon Musk 'has suggested the idea of building a '£20 trillion' underground tunnel link from London to New York appears to be a genuine possibility,' according to the site LADbible, 'although he says he could do it for less.' (On X.com Musk posted that his Boring Company 'could do it for 1000X less money.')
This comes after the SpaceX boss, 53, who promises to revolutionise the way we travel, said his 'Starship' rocket could be used to transport passengers to any city in the world in under an hour.
