Overview
- The Aerocity hub will link the Airport Express Line with the Tughlakabad–Aerocity Golden Line, with provision to add the proposed NCRTC corridor to Alwar for a triple interchange.
- DMRC says the upgraded station will offer platform‑to‑platform transfers on one side and paid‑area concourse connectivity between the two metro lines.
- The extension approved by the Union cabinet on December 24 covers about 2.263 km from Aerocity to the IGI Airport Terminal 1 station on the Magenta Line.
- Connectivity gains include direct metro access to Terminal 1 and quicker transfers to Terminals 2 and 3, benefiting south Delhi areas such as Tughlakabad, Ambedkar Nagar and Khanpur.
- Phase‑4 works are well advanced, with DMRC indicating TBM tunnelling later in 2026 and a target to integrate the T1 spur by early 2027.
