Hosts Ade Adepitan, Anita Rani, Ant Anstead and Dan Snow go to the heart of one of the world’s most crowded and thriving cities to find out how New Yorkers get about, how they eat and how they relax.

The first of this three-part series explores transport, and Anita goes behind the scenes of the world’s largest railway station – Grand Central  – which has 46 platforms compared to London Waterloo’s 19 and is used by 3.1 million commuters on weekdays.

A new station is currently being built, with an incredible 10 underground storeys, and Ant is given special access to the $10 billion project.
