Prime Minister Narendra Modi inaugurated India's first-ever underwater metro route in Kolkata, a landmark project showcasing the nation's stride towards infrastructure development.

• The underwater service is part of the Howrah Maidan-Esplanade section of Kolkata Metro's East-West corridor, which will cover a distance of 16.6 km under the Hooghly river.
• The metro service will connect Howrah and Salt Lake -- the West Bengal state capital's twin cities. Three out of six stations will be underground.
• It is expected to zoom through a 520-meter stretch under the Hooghly in just 45 seconds.
