Given that Mumbai's suburban railway network is often touted as the busiest in the world - transporting over 7 million people daily - it's a bit strange that so few photos of the operation exist on RP. Trains operate on 3- or 4-minute headways at nearly all hours of the day, and most assignments are held down by Siemens-built EMUs (that bear a passing resemblence to an LRC locomotive, no?) as seen here with a smartly-painted inbound set on the Central Railway headed for Chhatrapati Shivaji Terminus (better known as Mumbai CST, formerly Victoria Terminus.) Passing through the northern suburb of Mulund, the train is slowing for its station stop.
