This is a list of stations of the Kolkata Suburban Railway, a suburban rail system serving the Kolkata Metropolitan Region in West Bengal, India.
The Kolkata Suburban Railway was opened in 1854. The system is operated by Eastern Railway and South Eastern Railway zone. Each route contains "slow" and "fast" tracks. "Slow" tracks are dedicated tracks for suburban trains, while "fast" tracks are shared with long-distance trains operated by Indian Railways. Some railway stations on the network serve both suburban as well as long-distance trains.
The Kolkata Suburban Railway comprises five major lines – Eastern line, South Eastern line, Circular line, South lines and Chord link line. Each of these corridors may consist of additional lines that may intersect with each other. The system uses rolling stock of broad gauge and consists of largely at-grade and short segments of elevated and embankment lines. The railway system is open from about 0400 to 0100 and has an average daily ridership of 2-3 million commuters. It is the biggest suburban rail network in India, with a record of 400+ stations and a total of 1,501 km (933 mi); it is the world's 7th longest suburban railway network.[citation needed]
