Mumbai, the capital city of the State of Maharashtra and the financial capital of India, is the second most populous city in India. With limited land space, Mumbai’s population density is the second highest in the world. Immense pressures are put on Mumbai’s transport system. The Mumbai suburban railway network transports 8 million passengers daily, accounting for 78% of the total passenger kilometers. Traffic in Mumbai has been growing, and the existing suburban railway network has not been able to meet the growing demand for public transport infrastructure. As a result, during the peak hours, the trains operate far beyond their capacity, with more than four times the designed capacity of passengers on the trains. The network also faces safety concerns with daily fatalities due to reasons associated with the crowded trains.
