Magenta Line (Delhi Metro)

Summary of phased extensions

As of April 2026, on the entire approved "Botanical Garden – Krishna Park Extension and Deepali Chowk – Majlis Park – Indraprastha - Inderlok" route, 50.72 km out of total 89.73 km route and 33 stations out of total 57 stations are operational, with 39.01 km route and 24 stations under-construction/approved.

Phase 3

Phase-3 Magenta line was initially scheduled for completion in December 2016, but the timeline was extended due to challenging tunnelling conditions. Trial runs began in August 2017. The line was inaugurated in two phases: the first section, from Botanical Garden to Kalkaji Mandir, was opened to the public on 25 December 2017.^[7] The second phase was inaugurated on 28 May 2018, with the remaining section becoming operational and open for public use on 29 May 2018 at 06:00 IST.^[8]

A stretch of 8.679 km (5.393 mi), comprising 9 stations on the Botanical Garden–Kalkaji Mandir section, was opened to the public on 25 December 2017. The portion of 24.82 km (15.422 mi) of the line was opened to public on 28 May 2018 and a small stretch of 2.8 km (1.740 mi) the section of Phase IV was opened on 5 January 2025.^[9]

The stretch of 9.92 km (6.16 mi) comprising 7 stations from Deepali Chowk to Majlis Park of Phase IV was opened on 8 March 2026.

Phase 4

Under this phase, the line will be further extended from Janakpuri West to Ramakrishna Ashram Marg, providing interchanges with Green, Red, Yellow, Pink and Blue lines, and improving connectivity in the northern parts of Delhi. For this, the existing depot of Pink Line at Mukundpur is being upgraded to service Magenta Line trains also. The extension is expected to be fully completed by December 2027.^[10]A small section between Janakpuri West and Krishna Park Extension is operational since 5 January 2025.^[11]

Trial Runs were started in November 2025 between Majlis Park and Deepali Chowk stations using the new Alstom Metropolis trains. 3 stations in this stretch, namely Pitampura, Prashant Vihar and North Pitampura have been renamed to Madhuban Chowk, Uttari Pitampura - Prashant Vihar and Haiderpur Village respectively. This section was opened on 8 March 2026.

It was decided that the Inderlok-Indraprastha corridor under Green Line's extension for Phase 4 will now be implemented as an extension for Magenta Line instead, which will bring the total corridor length from Botanical Garden to Inderlok to about 89 km, making it the longest metro line in Delhi. Consequently, the line will form an interchange with itself at Nabi Karim. The foundation stone of this stretch was laid on 8 March 2026 by Prime Minister Narendra Modi.

Phase 5A

A 9.913 kilometres (6.160 mi) extension under Phase 5A was approved by the Union Cabinet at a cost of ₹9,570.4 crore (US$1.0 billion).^[12] This new corridor, which would be completely underground, will begin from Ramakrishna Ashram Marg on the Blue Line–Magenta Line interchange and have the following stations: Shivaji Stadium, Yuge Yugeen Bharat, Central Secretariat, CCS Building, India Gate, War Memorial–High Court, Baroda House, Bharat Mandapam, and will end at Indraprastha on the Blue Line–Magenta Line interchange.
