The length of operational metro rail projects has reached 824 km, and work on another 1,039 km is in progress, as per Housing and Urban Affairs Minister Hardeep Singh Puri. The figure was zero in 2002. This is a result of advocating for bringing more public transport, Puri stated, and that is why we have gone from 0 to 824 km, and another 1,039 km coming up. India is already one of the largest metro operators, Puri said adding that the country would soon be the second largest metro operator in the world. The central government has been encouraging public transport under different schemes. Contact: Ministry of Housing and Urban Affairs Website: mohua.gov.in
