Kolkata Metro holds a special place in Indian history as the country's very first underground metro, opened in 1984. Its Blue Line still runs the original north-south spine from Dakshineswar down through the heart of the city to Kavi Subhash, and remains one of the cheapest metro rides anywhere in India. The newer Green Line, or East-West Metro, links Howrah and Sealdah — two of India's busiest railway stations — and carries a world first: a stretch that runs in a tunnel beneath the Hooghly River, the first under-river metro in the country.
