Magenta Line To Extend To 89 Km, 65 Stations as Longest Delhi Metro Corridor

The Magenta Line (Line-8) of the Delhi Metro is poised to become the longest corridor in the entire network upon completion of ongoing and approved extensions under Phase-IV and the recently sanctioned Phase-V(A). According to the Delhi Metro Rail Corporation (DMRC), the fully expanded line will stretch approximately 89 kilometres from Noida Botanical Garden in the south to Inderlok in the northwest, surpassing other existing corridors in length and featuring the highest number of interchange and underground stations.

The expansion integrates several key segments, including the Phase-IV corridor from Indraprastha to Inderlok, which will now serve as an extension of the Magenta Line, along with the approved Phase-V(A) extension from Ramakrishna Ashram Marg to Indraprastha via Central Vista. Once operational, the entire corridor from Botanical Garden to Inderlok will comprise 65 stations, of which 40 will be underground. This marks a significant increase from the current operational sections, which include 26 stations spanning about 40 km, with recent additions like the short extension to Krishna Park Extension opened in early 2025.

A standout feature of the expanded Magenta Line will be its extensive interchange network, with 21 interchange stations in total—up from the current four (Kalkaji Mandir, Botanical Garden, Janakpuri West, and Hauz Khas). An additional 17 interchanges are planned, including key points such as Kalindi Kunj, Chirag Delhi, Terminal-1 IGI Airport, Majlis Park, Azadpur, Central Secretariat, New Delhi, and Inderlok. Four stations—Central Secretariat, Azadpur, New Delhi, and Inderlok—will function as triple interchanges, facilitating seamless transfers across multiple lines and significantly reducing travel times across the National Capital Region (NCR).

The Magenta Line, already India's first fully driverless metro corridor on its operational stretches since 2021, will continue to operate driverlessly throughout its extended length. Officials highlight that the enhanced connectivity will improve cross-city mobility, ease congestion on roads, and better serve densely populated and commercial areas. The developments follow the Centre's approval of Phase-V(A) in late December 2025, integrating previously separate corridors into a unified Magenta Line route.

This milestone underscores the Delhi Metro's ongoing expansion to meet growing ridership demands in one of the world's largest urban agglomerations. Construction timelines for the remaining segments vary, but the DMRC anticipates substantial progress in the coming years. Commuters can expect improved access to major hubs, airports, and residential zones once the full corridor is commissioned, further solidifying the Magenta Line's role as a backbone of Delhi's public transit system.
