The sole selection criterion for picking a station is the number of passengers passing through it. Other parameters should also be included. For instance, a station that is now not used by many passengers but is very close to a developing business hub, such as Kanjur Marg station is to Powai, can be developed to divert road commuters to rail.
After the United States, Russia and China, India is the fourth country with the largest rail network, but the country does not have any high-speed rail lines. The fastest train in India, the Bhopal Shatabdi, currently has a top speed of 150 km/h (93 mph).
High-speed trains have been introduced by France, Germany, Japan and China among other countries, and can provide economic benefits in countries such as India where more than 20 million passengers use the train per day as the main means of transport.
