Transatlantic tunnel

Proposals for a tunnel between Europe and North America

A transatlantic tunnel is a theoretical tunnel that would span the Atlantic Ocean between North America and Europe possibly for such purposes as mass transit. Some proposals envision technologically advanced trains reaching speeds of 500 to 8,000 kilometres per hour. Most conceptions of the tunnel envision it between the United States and the United Kingdom ‒ or more specifically between New York City and London.
