The idea of a Transatlantic Tunnel connecting the US and UK has resurfaced after new developments in the technology known as Hyperloop.
The tunnel has been estimated to cost more than £15 trillion, could take more than 700 years to build and there's no viable design yet, but you'd get from London to New York in under an hour if all those obstacles were overcome.
Even the idea of a getting a train between London and New York is difficult to imagine, but it seems there is a chance that one day it could be a reality. That is if someone, somewhere, is willing to cough up the £15.5 trillion it has previously been estimated to cost. Oh, and that someone, somewhere also needs to come up to with a viable design too.
