Q. What is Suburban rail????
Ans. Many cities have their own dedicated suburban networks to cater to commuters. Currently, suburban networks operate in Mumbai, Chennai, Kolkata, Delhi, Hyderabad, Ahmedabad, Pune and Lucknow-Kanpur. Mumbai, Hyderabad, Pune and Lucknow-Kanpur do not have dedicated suburban tracks but share the tracks with long distance trains. New Delhi, Kolkata, and Chennai have their own metro networks, namely the New Delhi Metro, the Kolkata Metro, and the Chennai MRTS, with dedicated tracks mostly laid on a flyover.
Mumbai's suburban trains handle 6.3 million commuters daily.

One unit of an EMU train consists of one power car and two general coaches. Thus a nine coach EMU is made up of three units having one power car at each end and one at the middle. The rakes in Mumbai run on direct current, while those elsewhere use alternating current. A standard coach is designed to accommodate 96 seated passengers, but the actual number of passengers can easily double or triple with standees during rush hour.
