Currently, the over 22-km Airport Express Line or Orange Line spans between Dwarka Sector 21 and New Delhi stations, and authorities plan to connect the Noida airport with the existing metro networks in Delhi and Noida. The Aqua Line of about 29 km with 21 metro stations connects Sector 51 station in Noida and Depot station in Greater Noida. A 300-metre walkway links the Sector 51 station on the Aqua Line of Noida Metro and the Sector 52 station on Blue Line of the Delhi Metro.
The plan aims to enhance mobility through a rapid transit network and link it to the state-of-the-art new Noida airport. The feasibility study for the Greater Noida-Noida international airport corridor has already been completed following which the DPR will be prepared now. For the other section connecting Greater Noida and the Airport Line, the feasibility study will be carried out according to the MoU. While the Greater Noida-Noida international airport section will be about 36 km long, the Greater Noida-Airport Line corridor will span across 38 km. Both these sections are being planned as high-speed corridors on the lines of the presently operational Airport Express Line which connects New Delhi with Terminal 3 of the IGI Airport.
