INDIA: The Asian Infrastructure Investment Bank is to provide US$500m towards the estimated US$2·22bn cost of the metro Line 4 project in Mumbai.

To be delivered by the Mumbai Metropolitan Region Development Authority, the project is due to be completed in 2021.

Line 4 would run on a 32 km elevated alignment between Wadala in the south and Kasarvadavali in the north via Ghatkopar, Mulund and Thane. Of the 32 stations, four would provide interchange with other metro lines.

CBTC signalling would be installed, and the line would be electrified at 25 kV AC. A fleet of 216 air-conditioned cars would be maintained at two depots.
