Bihar moved a step closer to Chief Minister Nitish Kumar's dream of a Metro train service in Patna with the state cabinet Tuesday approving the proposal to prepare a detailed project report (DPR).

Cabinet Secretary Brajesh Mehrotra told media persons here that state cabinet has selected Rail India Technical and Economic Service (RITES) for the purpose. 

"RITES will prepare DPR for the Metro rail in Patna," he said.

Earlier, the state government had said that Metro rail would be a reality in Patna by 2016. The project is set to cover a distance of 40 km and is estimated to cost Rs.8,000 crore.
