In the last instalment of his interesting travelogue of extreme railway journeys across the world’s toughest terrains, presenter Chris Tarrant takes a trip through India on the Konkan line. The Konkan railway runs down the west coast of India, connecting the port cities of Mumbai and Mangalore.

As a result, western India remained undeveloped, until a brave Indian engineer took on the daunting task. Known as ‘The People’s Railway’, the line opened in January 1998, finally connecting the remote villages along the route to the outside world.
