It is reported that Mumbai Metropolitan Region Development Authority's Charkop Bandra Mankhurd Metro Rail project will be implemented on a public private partnership basis.

Earlier, the government had planned to develop the remaining metro lines on its own. The first corridor linking the eastern suburb of Ghatkopar to western Versova is already under construction and is being built by the Mumbai Metro One on the PPP model.

The Mumbai Metro One was formed by a consortium led by Reliance Energy Limited.
