Monsoon Railway traces the amazing stories of some of the 1.5 million people who work for the world's greatest railway. For the last 150 years the railway in India has driven social and economic development in the country, and it is a railway on which the billion-strong population depends. Focusing on an area in the North East of India - Assam and Bengal - Monsoon Railway captures a rare snapshot of the lives of those who work on the network, and follows three workers from July to September 2004 during the unforgiving rains of the summer monsoon.
