20. Grand Central Terminal Has the Largest Basement of Any Building in New York City

Grand Central Clock

The basement covers 49 acres, from 42nd to 97th street. The entire City Hall building could fit into its depth with a comfortable margin of room to spare. Today, the MTA is in the midst of an ambitious project to bring Long Island Rail Road trains into the terminal via the East Side Access Project, making Grand Central even larger and deeper.

These will be the deepest train tunnels on earth, at 90 feet below the Metro North track and over 150 feet below the street. It will take 10 minutes to reach these tunnels by escalator, at their deepest point.
