Under Water Metro In Kolkata Starting Date

In a groundbreaking event, Prime Minister Narendra Modi will make history by inaugurating India's first-ever underwater metro tunnel in Kolkata on March 6, 2024. The Under Water Metro in Kolkata represents a remarkable feat of engineering and innovation, showcasing the city's commitment to modernization and development. This project marks a significant milestone for Kolkata's transportation system, offering commuters a unique and efficient mode of travel beneath the surface of the Hooghly River. Get ready to embark on an unforgettable journey through the depths of Kolkata with the Underwater Metro!


Deepest Metro Station in India

In April 2023, the first metro train made its historic journey to Howrah Maidan station, breaking records as the deepest metro station in the country at a staggering 33 meters below the surface. Descending into the underground depths, passengers are transported through an underwater tunnel beneath the Hooghly River, navigating through darkness with only occasional glimpses of water above them. The engineering marvel is a testament to human innovation and advancement in transportation infrastructure. 

Under Water Metro in Kolkata Route

Diving into the depths of innovation, the underwater metro route in Kolkata is a marvel of modern engineering. Stretching 4.8 kilometers beneath the city, this aquatic pathway will soon whisk commuters from Howrah Maidan to Esplanade with seamless efficiency. 

As part of the ambitious East-West Metro corridor, it forms a vital link connecting key locations like Salt Lake Sector V, bridging gaps and fostering connectivity across West Bengal's urban landscape. The underwater metro route represents progress and vision, propelling Kolkata towards a future where transportation transcends boundaries - both physical and metaphorical - delivering passengers to their destinations with speed and grace. 

Number of Ststion Covering Under Water Metro in Kolkata

The underwater metro route in Kolkata is a marvel of modern engineering, consisting of 17 stations spanning from Teghoria (Haldiram) in the east to Howrah Maidan in the west. With 11 elevated and 6 underground stations covering a total distance of 22 km, this route is set to revolutionize transportation in the city. Connecting India's largest commuter railway terminals, Howrah and Sealdah, as well as business districts like BBD Bagh and Salt Lake Sector V, it is expected to attract a massive ridership. Not only will it link the industrial hub of Howrah with the IT hub of Sector 5, but it also boasts India's biggest underwater metro tunnel and deepest metro shaft at Howrah station - an impressive feat that showcases Kolkata's commitment to innovation and progress.

East West Metro Tunnel

The East-West Metro Tunnel in Kolkata, West Bengal is a remarkable feat of engineering that runs underneath the Hooghly River. This impressive underwater river tunnel spans an incredible length of 10.8 km and has a width of 5.5 meters, making it the largest of its kind in India designed specifically for metro rail service. A standout feature of this tunnel is the 520-meter stretch that passes under the river itself, with the roof reaching heights of about 30 meters from ground level. Completed in 2021, this tunnel serves as a vital link for the East West Metro Line operated by Kolkata Metro Rail Corporation, providing efficient transportation options for residents and visitors alike in bustling Kolkata. The construction and successful completion of this ambitious project showcase innovation and dedication to improving urban infrastructure in one of India's most vibrant cities.

Construction - Deepest Under Water Metro Station in Kolkata

The Deepest Underwater Metro Station in Kolkata is set to be the Howrah metro station, located on the west side of the Hooghly River. This ambitious project has faced numerous challenges, including realigning sections of the route due to land availability issues with the Government of West Bengal. The original plan for a station at Wellington had to be dropped for similar reasons. However, construction work at Howrah Maidan began in March 2016 and is being carried out by the Afcons – Transtonnelstroy JV team using advanced tunnel boring machines from Herrenknecht. The section passing through the river spans a distance of 520 meters at a depth of 30 meters, making it not only a remarkable engineering feat but also a crucial contribution to improving transportation infrastructure in Kolkata.

Tunneling under the Hooghly River began from Howrah Maidan's side, with TBM Rachna completing the task in just 36 days on 23 May. Following suit, TBM Prerna also successfully finished tunneling under the river on 21 June 2017. However, concerns arose during the Brabourne Road section of the project due to its proximity to heritage structures and old buildings. To address these issues, KMRC obtained permission from the Archaeological Survey of India in June 2017 and took steps to reinforce and temporarily relocate residents and shops in dilapidated buildings along this route. By November 2017, construction of the tunnel until Mahakaran station was completed without a hitch. Moving forward, careful planning continued for sections like Mahakaran–Esplanade where tunneling finished by March and April 2018 respectively after ensuring the safe relocation of affected parties. The upcoming Esplanade–Sealdah section is set to begin in May 2018 under ITD-ITD Cementation JV's supervision. 

Tunneling through the challenging terrain between Subhash Sarovar and Sealdah has been a monumental task, with 5490 meters of tunnel now in place thanks to ITD-ITD Cementation JV. The intricate network of cross-passes connecting the tunnels has also been skillfully completed. Despite setbacks like the collapse in Bowbazar caused by TBM hitting an aquifer, work resumed with determination in June 2020. Now, this section stands as a testament to the resilience and expertise of those involved in this impressive tunneling project.

Under Water Metro Line

The media's claim that the underwater metro tunnel project is a groundbreaking milestone in India is not entirely accurate. While the Hooghly River poses significant engineering challenges for tunnel construction, other metro lines in Indian cities have earned the title of "underwater." 

Kolkata Metro Line 1, operational since the 1990s, passes under the Circular Canal between Shyambazar and Belgachia stations. Similarly, Delhi Metro Line 2 runs beneath the Najafgarh Drain and Kushak Drain, while Chennai Metro Line 1 travels below the Cooum River from the Government Estate to Chennai Central Station. These existing underwater metro lines also deserve recognition for their innovative engineering feats.

Despite facing numerous challenges and setbacks, the tunneling works for the Esplanade-Sealdah section were finally completed in April 2023. The westbound tunnel proved to be particularly difficult, leading the Metro authorities to decide to run trains on a truncated route instead.

The transformation of the Esplanade metro station to accommodate the new railway racks marked a significant milestone in Kolkata's transportation system. The innovative use of a battery-powered locomotive to navigate the non-electrified section was a testament to modern engineering. As the trains made their inaugural journey beneath the Hooghly River, history was made with each wheel that rolled along the tracks. The addition of blue lights in the underwater tunnel section not only enhanced safety but also provided passengers with a surreal experience, unlike any other metro station in India.
