One of the reasons trams have gone out of favour in Calcutta is the Calcutta metro, a modern classic the locals are justifiably proud of. It's fast, clean and efficient, and the trains can get quite crowded as seen here. The network consists of one operational line (Line 1) and five lines currently under construction. It was the first such form of transportation in India, opening commercial services in 1984. Photography in the metro is strictly prohibited, this is a sneak shot taken by one of the members of a railway group I'm member of. (May 2009)
