Kolkata Metro Line 6 or the Orange Line of the Kolkata Metro, in the Indian state of West Bengal, is a rapid transit line that will connect New Garia with Netaji Subhas Chandra Bose International Airport via two satellite towns Salt Lake and New Town. It currently operates between Kavi Subhash and Hemanta Mukhopadhyay. This stretch will be one of the most important stretches of the metro because it will connect the southern and the eastern parts of the city with Kolkata Airport. The total distance of this route will be 29.87 km (18.56 mi).[1]
The trials of the 5.4 km (3.4 mi) Kavi Subhas-Hemanta Mukhopadhyay station at Ruby crossing segment was covered in eight minutes without stoppages. The speed trials for the East-West Metro during the CRS inspection in 2019 had been at 80 km/h (50 mph).[4] It connects Line 1 at Kavi Subhash and will eventually connect Lines 2 and 4.

This project was sanctioned in the budget of 2010–11 by Mamata Banerjee with a project deadline of six years.[5] The execution of this project has been entrusted to RVNL at a cost of Rs 3951.98 crore. It will help to reduce travel time between the southern fringes of Kolkata to Netaji Subhas Chandra Bose International Airport and will have 23 elevated stations, 1 underground station and 1 at-grade. The terminal Airport station being the underground one.
Work for construction of the terminal station at New Garia for the 29.87 km (18.56 mi) Kavi Subhash-Biman Bandar (via Rajarhat) metro project finally resumed on 14 February 2017 with Rail Vikas Nigam Ltd (RVNL) demarcating the plot they require for the purpose.
The work has been delayed for years due to multiple issues. At first AAI objected the station above the ground, stating that this could be a threat for air traffic. Many underground utilities, power sub-station and water treatment plant had to be shifted. Encroachments and Land acquisition problems held up the project for multiple times.
The 5 km (3.1 mi) stretch from New Garia to Ruby Hospital was expected to start from 2018.[6] As of now, the station and associated metro viaduct connections are fully completed with trail runs being conducted over this and other phase 1 stations. RVNL planned to launch the metro over this truncated route before this year's Durga Puja, but was postponed due to signalling issues.[7]
The stations are named after eminent Bengali personalities.[5][11][12] and will have 22 elevated stations, 1 underground station and 1 at-grade. The terminal Airport station will be the underground one. This station will also have a yard and it will be the largest underground facility of India and city's first. It will be 550 m (1,800 ft) long and 41.6 m (136 ft) wide and will facilitate stabling and reversal of rakes, but it will not be a carshed. One can interchange to Line 4 at Dum Dum Airport, Line 2 at VIP Road (Haldiram) and Salt Lake Sector V and Line 1 at Kavi Subhash. At Kavi Subhash, Rail Interchange will be also available (Sealdah South Section).
On 4 January 2021 the state government decided to rename 9 metro stations in New Town area to their more prevailing names rather than using the old ones which were given during the planning phase. The state transport department has informed Housing Infrastructure Development Corporation (HIDCO) of the new names of the proposed nine metro stations between Nazrul Tirtha at the entry of New Town from Salt Lake Sector V till Chinar Park, the last station on the line before it turns right on VIP road towards Kolkata Airport.[13]
