Engineers have proposed cutting journey times from New York in the United States to London in the United Kingdom to 54 minutes, travelling on a magnetically raised train. The idea is that the train will travel through a tunnel floating in the Atlantic Ocean. The tunnel will be 150 feet below the surface of the sea and it will be nearly 5,000 kilometers long. The train will travel at 8,000 kph (20 times the speed of today’s fastest trains)
