Delhi Metro The first line of the Delhi Metro, the Red Line, was inaugurated by Atal Bihari Vajpayee, the Prime Minister of India, on 24 December 2002.[20] The Delhi Metro became the second underground rapid transit system in India, after the Kolkata Metro, when the Vishwa Vidyalayaâ€“Kashmere Gate section of the Yellow Line opened on 20 December 2004.[21] The first phase of the project was eventually completed in 2006,[22][23] on budget and almost three years ahead of schedule, an achievement described by Business Week as "nothing short of a miracle".[24]
History of rail transport in India India's first railway proposals were made in Madras in 1832.[1] The Red Hill Railway, the country's first train, ran from Red Hills to Chintadripet bridge in Madras in 1837. It was hauled by a rotary steam-engine locomotive manufactured by William Avery. Built by Arthur Cotton, the railway was primarily used to transport granite stone for road-building work in Madras.[1] In 1845, the Godavari Dam Construction Railway was built at Dowleswaram in Rajahmundry. Also built by Cotton, it supplied stone for the construction of a dam over the Godavari River.[1]
