In World’s Busiest Railway 2015, Dan Snow, Anita Rani and Robert Llewellyn experience the rush hour and go behind the scenes over four hour-long episodes to reveal the ‘everyday miracle’ that is India’s busiest railway station: the iconic Chhatrapati Shivaji Terminus in Mumbai. In Mumbai, rush hour is known as 'super dense crush load' and every day more than 1,500 trains pull in and out of its 18 platforms, on local and long distance routes, with more people travelling on the suburban network in Mumbai than travel on the whole of the UK rail network each day. With access to control rooms and signal boxes, driver’s cabs and engineering workshops, as well as the policemen, porters and dabba wallas who direct, help and feed travellers, this series will tell the story of the megacity of Mumbai - its station and its transport challenges. Without the railways, modern India simply wouldn’t exist and these programmes promise to be a revealing journey into the everyday workings of an extraordinary station.
