Howrah Metro,Asia's First Underwater Metro
Howrah Metro
1. The Legacy & History
Kolkata Metro (Blue Line): This is the pioneer. Started in 1984, it is India's first underground metro. It connects North (Dakshineswar) to South (Kavi Subhash).
Howrah Metro (Green Line): The game-changer. It created history in 2024 by introducing India's first Underwater Metro tunnel under the Hooghly River.
2. Geographical Marvel
Kolkata Metro: Runs deep beneath the congested streets of Kolkata. The deepest point was previously at Belgachia.
Howrah Metro: This line includes the deepest metro station in India—Howrah Maidan (33 meters deep). It travels through a 520-meter tunnel under the river.
3. Speed & Technology
Blue Line: Uses traditional technology, though newer rakes (Dalian & Medha) are faster and more comfortable.
Green Line: Equipped with state-of-the-art Automatic Train Operation (ATO) technology. The underwater section is covered in just 45 seconds at high speed.

The 45-Second Underwater Thrill: Engineering at its Best
The most breathtaking part of the Howrah Metro (Green Line) is the 520-meter stretch under the Hooghly River. While the journey across the river takes only 45 seconds, the technology behind it is world-class.
The Depth: The tunnels are built 13 meters below the riverbed and 33 meters below the water level.
Safety First: The tunnels are constructed using high-quality reinforced concrete segments with hydrophilic gaskets to ensure they are 100% waterproof.
The Experience: As the train enters the underwater section, the tunnel is illuminated with blue LED lights, giving passengers the surreal feeling of being under the water. It’s not just travel; it’s an engineering spectacle!
Is it Asia's First
The Howrah-Kolkata Underwater Metro is India’s first and one of the most unique underwater metro systems in South Asia. While there are underwater tunnels in countries like Japan and China (for high-speed rails or metros), the Howrah Metro is a monumental achievement because it is the first-ever transportation tunnel under a powerful, silt-heavy river like the Hooghly in this part of the continent.
