In New York City there is currently a project ongoing deep underneath Grand Central Terminal to add an entirely new 8-track, 350,000sqft station connecting Grand Central to the Long Island Railroad. Similarly, all materials for that project enter and exit from the other end of the project tunnel in Queens. New York City at ground level has no indication that the work is ongoing 140 feet below their… well, feet. Very neat!
