About Bombay Railway
Documentary in two one hour parts about the importance of the railways for the people of Mumbai in India. We meet the people working on and for the railway, as well as the hawkers selling their wares illegally to the passengers on board, constantly being chased by the railway police officers, and the runaway children who live around the railway. Bombay Railway won the award for Factual Programme of the Year at the Royal Television Awards in 2008.
