I once heard about a proposed train from New York to London. It would run in an evacuated steel tube submerged below the waves to avoid ships and storms. Because of the vacuum, the train could go fast enough to make the trans-Atlantic trip in under one hour. But the project would require 100 times the current annual steel output of the whole world, so it is not being attempted.
