First-ever underwater metro

• Prime Minister inaugurated the country’s first-ever underwater metro, the Howrah Maidan-Esplanade Metro section in Kolkata.

ABOUT THE METRO

• Kolkata’s new underwater metro is 6 km long.
• About 8 km runs underground from Howrah Maidan to Phoolbagan, including the tunnel under the Hooghly River, making it the deepest in the country. The rest is above ground.
• Stretching over 8 km, one section connects Howrah and Salt Lake, providing a vital link between these twin cities.
• The underwater metro has six stations, with three of them underground.
• The metro covers a 520 m river stretch in just 45 seconds, promising a quick and efficient mode of transportation.
• The train uses Automatic Train Operation (ATO), a cutting-edge system where the train advances to the next station when the motorman presses a button.
