About Grand Central Station
Firstly, the name you see above is technically wrong. The name of New York’s primary rail interchange is actually Grand Central Terminal – Grand Central Station is the name for the nearby post office.
It opened in 1871, and with its 44 platforms and 67 tracks, it stands as the world’s biggest train station.
Each face of the iconic clock at the centre of Grand Central Station's main concourse is made of precious opal - hence the estimated value of $10-20million.
