The trains in Mumbai carry more than 7 million people a day and are among the most crowded in the world. In rush hour, according to some estimates, more than 5,000 people can cram into carriages designed to carry no more than 1,700. Despite repeated efforts to reduce the death toll, around 4,000 people are killed every year on the network, many falling through the open doors. Local authorities have systematically failed to invest in transport infrastructure in the city, which despite pockets of extreme poverty is one of the wealthiest in India. The cheapest ticket on Mumbai’s train is a rupee while a year-long first-class season ticket for the most popular line on the entire network of 270 miles and more than 100 stations costs around Rs.3000.
