The Delhi Metro has been instrumental in ushering in a new era in the sphere of mass urban transportation in India. The swanky and modern Metro system introduced comfortable, air conditioned and eco-friendly services for the first time in India and completely revolutionized the mass transportation scenario not only in the National Capital Region but the entire country.
The DMRC opened its first corridor between Shahdara and Tis Hazari on 25th December, 2002. Delhi Metro is the world's 12th largest metro system in terms of both length and number of stations.
Presently, the Delhi Metro network consists of about 213 Km with 160 stations along with six more stations of the Airport Express Link. The network has now crossed the boundaries of Delhi to reach NOIDA and Ghaziabad in Uttar Pradesh,Gurgaon and faridabad in Haryana.
The Airport Express link between the Indira Gandhi International Airport and New Delhi has now propelled Delhi to the league of global cities which have high speed rail connectivity between the city and the airport.
The Delhi Metro has also contributed tremendously on the environment front by becoming the first ever railway project in the world to claim carbon credits for regenerative braking. DMRC has also been certified by the United Nations (UN) as the first Metro Rail and Rail based system in the world to get carbon Credits for reducing Green House gas emissions as it has helped to reduce pollution levels in the city by 6.3 lakh tons every year thus helping in reducing global warming.
According to a study, Delhi Metro has helped in removing about 3.9 lakh vehicles from the streets of Delhi.
