Calcutta Metro plays calming music

The Indian city of Calcutta is to begin playing calming classical Indian music at its underground railway stations in an effort to prevent suicides.

Posters are also being put up at all seventeen stations, urging people to choose life over death, including one quoting the writer and poet, Rabindranath Tagore, who won the Nobel prize for literature.

Fifty-nine people have attempted suicide since the Calcutta underground railway began operating in 1984.
