( CNN ) -- Away from the hustle and bustle of Delhi 's dusty streets , where rickshaws , crammed buses and the occasional elephant usually set the tone for a cacophonous commuting experience , there is an air-conditioned haven that is the pride of local residents : The Delhi Metro . Just eight years old , the Indian city 's transport system has been hailed as a great success story -- its trains run on time , platforms are clean and journeys are quick . The metro carries hundreds of thousands of daily commuters and has helped to reduce Delhi 's massive traffic and air pollution problems . Since the start of its first phase , it has saved around 300,000 tons of fuel , and its potential to reduce greenhouse emissions is `` quite substantial , '' according to Anumita Roychowdhury of India 's Center for Science and Environment .
