Line 3 (Purple Line) is a rapid transit metro line of the Kolkata Metro in Kolkata, West Bengal, India. A 6.5 kilometres (4.0 mi) stretch from Joka to Taratala of this line was inaugurated on 30 December 2022 and after extended to Majerhat on 6 March 2024. This line will span 15.08 kilometres (9.37 mi) from Joka in the south to Esplanade in the north with a future southward extension of 3.39 kilometres (2.11 mi) to Diamond Park from Joka. It will connect Blue Line at Park Street in central Kolkata and run in parallel with Blue Line up to Esplanade where it will connect with Green Line also. Line 3 is being built by Rail Vikas Nigam Limited.

Development

Around 8.5 kilometres (5.3 mi) of the project will be elevated and the rest of 6.32 kilometres (3.93 mi) of the metro line will be underground. The project is getting delayed due to nonavailability of land for the construction of train depot at Joka. In 2019, RVNL was given the land required for building the depot and the construction for its boundary wall and land development started in February 2019. Tenders for its construction and plant & machinery were invited in April 2020.

Construction was further delayed in September 2018 due to the Majerhat Bridge collapse, the metro was being built right next to the bridge.

Tender for Majherhat to Esplanade underground section has been floated in 1st week of December 2019.

By 15 September 2022, the stretch from Joka to Taratala has been fully constructed and electrification has been done. Testing trials are underway from Joka to Taratala using the old decommissioned Metro Rakes. Eventually in service there will be new air conditioned metro rakes. The stretch from Majerhat to Esplanade is under construction.

Prime Minister Narendra Modi inaugurated the Joka-Taratala stretch, including Joka metro station of Kolkata Metro's Purple Line on 30 December 2022 in the presence of West Bengal Chief Minister Mamata Banerjee and Indian Railway Minister Ashwini Vaishnaw. Some students from schools especially St Thomas Boys School, whose premises are utilised for planned Khidirpur metro station in this stretch, were granted the rare opportunity to be the first ones to ride in this Joka-Taratala stretch after the inauguration.

After lot of hardships and developmental work the Taratala-Majerhat section of Kolkata Metro Line 3 was inaugurated on 6 March 2024 by Prime Minister Narendra Modi, along with the truncated sections of Esplanade-Howrah Maidan under Line 2 and Kavi Subhash-Hemanta Mukhopadhyay under Line 6. The Mominpur-Esplanade section is expected to be open in 2028.

List of stations

The work has been sanctioned in 2010-11 for the new Metro line from Joka to B.B.D. Bagh for a length of 16.72 km (10.39 mi) at an anticipated cost of Rs. 2619.02 Crores. But, later the route was shortened and planned to terminate at Esplanade. A separate Depot was built by RVNL in Joka. The tender has gone to Simplex Infrastructures. The extension of this line to IIM and Diamond Park for 2 km (1.2 mi) has been sanctioned in the Budget of 2012–13 at a cost of Rs. 294.49 Cr. The execution of this work has been entrusted to RVNL.
