The decision of the central government to make private participation mandatory for all metro projects has been severely criticised by E.Sreedharan, who has been the architect of most of the metro projects in the country.
Metro is a service to the people and not based on high profits. That is why the Delhi Airport Metro line which was handed over to Reliance did not function well and Reliance left it and escaped. Now again it has started running.
The government decision making private participation mandatory in Metro projects is sense less and has to be abandoned. Metro system can not be destroyed by the love of the government for the private corporates.
