Magenta Line to become longest Delhi Metro corridor with maximum interchanges and underground stations

The Magenta Line (Line-8) of Delhi Metro network is set to emerge as the longest corridor of the Delhi Metro, featuring the highest number of interchange stations and underground stations, thereby significantly enhancing cross-city connectivity across the National Capital Region.

Longest Corridor:
Once Phase‑IV and Phase‑V(A) extensions are complete, the Magenta Line (Line‑8) will stretch ~89 km from Botanical Garden to Inderlok, making it the longest corridor in the Delhi Metro network.

Driverless Operations:
The entire line will function as a driverless metro corridor when fully operational.

Interchange Stations
- Current: 4 interchange stations (Kalkaji Mandir, Botanical Garden, Janakpuri West, Hauz Khas).
- Future: 17 additional interchange stations, bringing the total to 21.
- Triple Interchanges: Central Secretariat, Azadpur, New Delhi, and Inderlok will serve as triple interchange hubs.

Underground Stations
- Total Stations: 65.
- Underground: 40 stations will be underground, enhancing connectivity across dense urban areas.

Engineering Highlights
- Haiderpur Badli Mor: Highest elevated metro station in the system (rail level ~28.36 m).
- Hauz Khas: Deepest underground metro station (~29 m).

Impact
- Connectivity: Seamless cross‑city travel with reduced travel times.
- Decongestion: Relieves pressure on major corridors.
- Integration: Strengthens interchange facilities, making the Magenta Line the backbone of Delhi’s metro network.

This expansion positions the Magenta Line as the most interconnected and technically advanced corridor in the Delhi Metro system, combining scale, engineering excellence, and passenger convenience.
