Dan Snow, Anita Rani and Robert Llewellyn are in India, exploring the world's busiest railway. From their base at the Chhatrapati Shivaji Terminus in Mumbai they reveal the science, systems and staff responsible for keeping this supersized transport system running to schedule.
In this opening episode Dan, Anita and Robert try commuting Mumbai-style, tackling 'super dense crush load' on the world's busiest commuter trains. Passengers hang from the sides of trains and cross the tracks, so they're in for quite a ride.
And our cameras are on board with the astonishing dabba wallahs - a crack team of couriers who deliver 200,000 home cooked lunches to offices all over Mumbai.
