Purple Line History, Facts & Expansion

Kolkata Metro Line 3, also known as Joka-Esplanade Metro, is an upcoming metro line that will significantly expand Kolkata's metro network.
Prime Minister Narendra Modi inaugurated the Joka-Tartala section, including Joka metro station, of the Purple Line of the Kolkata Metro on 30 December 2022.
The line runs on a two-track system, which ensures safe and efficient movement of trains.
The Purple Line features a combination of elevated and underground tracks, providing a diverse and interesting commuting experience.
In the future, there are plans to extend this route by 15.08 kilometers from Joka in the south to Esplanade in the north and by 3.39 kilometers from Joka to Diamond Park.
It will connect Kolkata Metro Line 1 at Park Street in central Kolkata and run parallel to Esplanade in central Kolkata where it will also connect Kolkata Metro Line 2. Line 3 is being constructed by Rail Vikas Nigam Limited.
The line will have interchange stations at Esplanade (with Line 1) and Majerhat (with Line 2), providing convenient connectivity to other parts of the city.

Phase II extension of Kolkata Metro's Purple Line

The Kolkata Metro Purple Line extension is expected to be completed by late 2028 or early 2029. The line will connect to the Blue Line at Park Street in central Kolkata and run parallel to the Blue Line until Esplanade, where it will also connect to the Green Line. Approximately 8.5 kilometres (5.3 mi) of the project will be elevated, and the remaining 6.32 kilometres (3.93 mi) will be underground.
