New York Penn Station, New York

This major transportation hub sits under Madison Square Garden . Penn Station accommodates Amtrak, the Long Island Railroad and New Jersey Transit railroad lines, not to mention a major subway station. Not surprisingly, it can get overwhelmingly crowded, especially at rush hour. The original 1910 Pennsylvania Station was a splendid beaux-arts building complete with a glass roof, marble floors and a resplendent lobby. Tragically, it was demolished to make way for the new Madison Square Garden.
