Mahakaran Metro Station
Mahakaran (also known as New Mahakaran) (both names are officially correct), is a metro station on Green Line of Kolkata Metro, located in B.B.D. Bagh. There are many British heritage buildings near the station with the Lal Dighi adjoining it. The tracks leaving the station towards Howrah go underneath the Hooghly river through the biggest underwater metro tunnel of India. The station was completed and opened on 6 March 2024. The station, though comparing without platform screen doors, may look similar to any Blue Line underground station, but it is actually very different as it is designed with world class facilities and murals that pay tribute to the locality and Indian freedom fighters. The nearest railway station is B.B.D. Bagh railway station. Just before the tunnel enters the underwater segment, lies a ventilation shaft on the Kolkata bank of Hooghly River, which is the deepest of its kind in India, at below ground level.

Ventilation Shaft
In subterranean civil engineering, ventilation shafts, also known as airshafts or vent shafts, are vertical passages used in mines and tunnels to move fresh air underground, and to remove stale air. In architecture, an airshaft, also known as a lightwell, is typically a small, vertical space within a tall building which permits ventilation of the building's interior spaces to the outside. The floor plan of a building with an airshaft is often described as a "square donut" shape. Alternatively, an airshaft may be formed between two adjacent buildings. Windows on the interior side of the donut allow air from the building to be exhausted into the shaft, and, depending on the height and width of the shaft, may also allow extra sunlight inside.

Island Platform
An island platform (also center platform (American English) or centre platform (British English)) is a station layout arrangement where a single platform is positioned between two tracks within a railway station, tram stop or transitway interchange. Island platforms are sometimes used between the opposite-direction tracks on twin-track route stations as they are cheaper and occupy less area than other arrangements. They are also useful within larger stations, where local and express services for the same direction of travel can be accessed from opposite sides of the same platform instead of side platforms on either side of the tracks, simplifying and speeding transfers between the two tracks. The historical use of island platforms depends greatly upon the location. In the United Kingdom the use of island platforms on twin-track routes is relatively common when the railway line is in a cutting or raised on an embankment, as this makes it easier to provide access to the platf ...

Hooghly River
The Hooghly River (, also spelled ''Hoogli'' or ''Hugli'') is the westernmost distributary of the Ganges, situated in West Bengal, India. It is known in its upper reaches as the Bhagirathi. The Bhagirathi splits off from the main branch of the Ganges at Giria, India, Giria. A short distance west, it meets the man-made Farakka Feeder Canal, which massively increases its flow. The river then flows south to join the Jalangi River, Jalangi at Nabadwip, where it becomes the Hooghly proper. The Hooghly continues southwards, passing through the metropolis of Kolkata. Thereafter, it empties into the Bay of Bengal. Its tributaries include the Ajay River, Ajay, Damodar River, Damodar, Rupnarayan River, Rupnarayan, and Haldi River, Haldi.

Underwater Tunnel
An underwater tunnel is a tunnel which is partly or wholly constructed under the sea or a river. They are often used where building a bridge or operating a ferry link is unviable, or to provide competition or relief for existing bridges or ferry links.Sullivan, WalterProgress In Technology Revives Interest In Great Tunnels New York Times, June 24, 1986. Retrieved 15 August 2010. While short tunnels are often road tunnels which may admit motorized traffic, unmotorized traffic or both, concerns with ventilation lead to the longest tunnels (such as the Channel Tunnel or the Seikan Tunnel) being electrified rail tunnels. Types of tunnel Various methods are used to construct underwater tunnels, including an immersed tube and a submerged floating tunnel. The immersed tube method involves steel tube segments that are positioned in a trench in the sea floor and joined together. The trench is then covered and the water pumped from the tunnel. Submerged floating tunnels use the law of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
