Chhatrapati Shivaji Maharaj International Airport - T2 (also called as CSMI Airport - T2) is an underground metro station of the Aqua Line 3 of Mumbai Metro in Mumbai, India. It was opened to public on 7 October 2024.
The station's conception dates back to early planning phases of Mumbai MetroâÂÂs Aqua Line 3, when the Mumbai International Airport Limited (MIAL) proposed a financial partnership to integrate a metro station directly with T2. In August 2022, the Government of Maharashtra approved a significant cost escalation of over â¹10,000 crore for the Aqua Line 3 project, as reported by The Times of India.
MIAL committed to funding three key stationsâÂÂT2, Marol Naka, and Sahar RoadâÂÂwith an estimated contribution of â¹777 crore. To recover this amount, a âÂÂmetro componentâ was added to the User Development Fee (UDF) charged to air passengers between 2016 and February 2023, according to a report by the Financial Express.
Construction of the station was undertaken by the Mumbai Metro Rail Corporation (MMRC) as part of the broader Aqua Line 3 project. The station includes modern commuter amenities such as customer service counters, escalators, lifts, shops, ATMs, and multiple entry/exit points to accommodate peak-time passenger flow. The station is also set to host India's longest escalator, at 21 metres in length.
When first opened, the metro station was located 500 meters away from the airport terminal along poorly signposted public roads. A direct bridge from Exit 1A to the airport terminal opened in August 2025, reducing the distance to 100 meters.
The station was opened to the public on 7 October 2024 as part of Phase 1 of Aqua Line 3, which connected Aarey to Bandra-Kurla Complex (BKC). This marked a major milestone in expanding MumbaiâÂÂs rapid transit network and improving airport accessibility.
