Earlier, this line was planned to be divided into two lines: the up line and the down line. Both were meant to start from Noapara Metro Station and meet at Bimanbandar railway station. The up line was meant to run along with the Belghoria express and meant to have two new stations at Ramkrishna Pally and Shantinagar. The down line was meant to use Old Dum Dum Cantonment - Biman Bandar section's alignment, viaducts, and stations. However, the plan changed later, and now both lines will pass through the Dum Dum Cantonment - Bimanbandar section. The project will be completed in three phases. The first phase of work from
Noapara to
Jai Hind was opened on 22 August 2025. In the second phase work from Jai Hind to New Barrackpore will be done and in the last phase from New Barrackpore to Barasat work will be done. But the development work from New Barrackpore to Barasat has been stalled for the last eight years since it was sanctioned because of encroachments. and the
Airport Authority of India objected to the elevated stretches from New Barrackpore to Barasat. Later, after objections from AAI, a decision was taken to convert this into an underground stretch. On 29 June 2019 sanction for material modification for underground construction at an additional cost of was sent to the Railway Board by Metro. For this underground tunneling, AAI has agreed to shift its fuel tanks, buildings, and cables, and the project is expected to start in 2020. An amount of Rs 227 crore contract to build this station, along with a mostly at-grade section from the Bagjola Canal to the existing ramp of the Airport Circular Railway track was awarded to Senbo Engineering Limited back in June 2011. Since then, the station's civil structure has been built, but work on the at-grade track section could not be started due to land acquisition issues along the line's proposed alignment. But the rehabilitation work was completed in 2020, and the work is going smoothly. Recently, girders were placed over Eastern Railway tracks. The metro station is set to be operational by Mid-2025. Construction of an underground integrated station for
Orange Line and Yellow Line has begun at NSCBI Airport land just away from the terminal building. The development of New Barrackpore to Barasat was supposed to go elevated to cut down the expenses, but the stretch was in doubt due to a huge encroachment problem. But in February 2021, Prime Minister
Narendra Modi gave his nod to construct this stretch underground, giving respite to thousands of families who were supposed to be evicted for the development of the elevated stretch. To lower the cost of the underground work, latest technology
TBM will not be used, instead old technology of cut and cover method will be used for metro. Yellow Line has been divided into three phases. • Phase 1: Noapara - Jai Hind (Biman Bandar) (Operational) • Phase 2: Jai Hind (Biman Bandar) - Micheal Nagar (Under construction) • Phase 3: Micheal Nagar - Suripukur (Planned, construction will begin soon) ==See also==
