With 44 platforms, Grand Central Terminal is the biggest train station in the world. Its construction lasted 10 years and was completed in 1913. Today, up to one million passengers travel through it every day. It is hard to imagine that this masterpiece of classic French architecture inspiration was almost destroyed in the seventies. We explore this incredible station, its historical and architectural footprint, as well as its unique mode of operation through the eyes of New Yorkers working in the station or commuters who travel through it to get to work, and take viewers to secret places like the tennis court hidden behind the gigantic stone-facade. From the series Grand Central Stations.
