Details of the suggested routes were announced by Delhi Metro Rail Corporation Ltd managing director E Sreedharan at a meeting with Pune Municipal Corporation (PMC) officials on Friday. PMC has appointed Delhi Metro as consultant to study the planning of metro rail for the city.

“The three corridors for the metro rail system — from Warje to Chinchwad of 22 km, Shivajinagar to Kalyaninagar of 13 km and Swargate to Agriculture College of 10 km — have been identified in the preliminary study,” Sreedharan said.

He said Warje-Chinchwad corridor would be 22 km long and pass through Karve Road, Jungli Maharaj Road, Shivajinagar and Mumbai-Pune highway. The Shivajnagar-Kalyaninagar corridor of 13 km would pass through Raja Bahadur Mills Road and Ahmednagar Road while Swargate-Agriculture College corridor of 10 km would pass through Shivaji Road.

“The Warje-Chinchwad and Shivajinagar-Kalyaninagar corridor will be elevated corridors passing from the centre of the existing roads while the Swargate-Agriculture College corridor will be underground,” Sreedharan said, adding the detailed project report (DPR) would be ready within four months.

He said the estimated cost of the project would be Rs 90 to 100 crore per km, which includes cost of land, structure, tracks, electric system, signalling and depot.

He said the options for funding for the project include full funding from the government, public-private participation, build-operate-transfer option or raising money from the market by a company formed jointly by the state and Union governments.

“The project cannot be implemented under the Jawaharlal Nehru National Urban Renewal Mission as it is a commercial project,” he said.

Sreedharan said the Bus Rapid Transit System (BRTS) would not be affected by the metro rail system and minimum displacement of citizens and buildings will take place. One corridor would take three-and-half years to be ready, he added.

Municipal commissioner Praveensinh Pardeshi the comprehensive mobility plan by Infrastructure Leasing and Financial Services Ltd (IL&FS) would be available in three months. “The two reports will be used for planning for public transport in the city,” he said.
