Chennai Monorail was a proposal for a number of lines as part of mass transit system for the Indian city of Chennai. Originally the city planned to use monorail on all lines but many were subsequently changed to railways as part of the Chennai Metro. The first tender was requested in 2011 but conditions were watered down several times. Tenders have lapsed thrice after failing to attract bidders. In the 2014 plan there were three remaining monorail corridors. As of January 2015, only two bidders remain after the Request For Qualification process of the ongoing bidding attempt.
