Timeline

Year	Month and date	Event type	Details	Associated parts
1956	November 1	Prelude	Delhi becomes a union territory of India, as a result of the States Reorganization Act of 1956.[6] Planning and research on a transportation system leading to the development of the Delhi metro begin around this time.[7]
1969		Prelude	The concept of mass rapid transit for New Delhi emerges from a traffic and travel characteristics study conducted in the city. This study lays the foundation for future planning and development of the city's transit system.[8]
1984		Prelude	The Urban Arts Commission proposes the development of a multi-modal transport system, which includes building three underground mass rapid transit corridors and augmenting the city's suburban railway and road transport networks. This proposal aims to address the growing transportation needs of the expanding city.[9]
1992		Prelude	An attempt to privatize the bus transport system results in significant issues, including poorly-maintained, noisy, and polluting buses operated by inexperienced drivers. This leads to long waiting times, unreliable service, overcrowding, and an increase in road accidents. This outcome highlights the need for a reliable public transit solution, and would influence the development of the Delhi Metro system.[10]
1995	May 3	Early development	The Delhi Metro Rail Corporation (DMRC) is established for the implementation and subsequent operations of the mass rapid transit system in Delhi. It is incorporated with equal equity participation from the Government of India and the Government of National Capital Territory of Delhi.[11]
1996	September	Early development	The Union Cabinet approves the initial project, which includes three corridors. This approval marks a significant step towards the realization of a modern mass rapid transit system for New Delhi.[12]
1997		Funding	Japan grants official development assistance loans to finance the first phase of the metro system. This funding is crucial in advancing the construction and development of the Delhi Metro.[12]
1998	October 1	Early development	Construction works to build the rail mass transit system begin, following more than 40 years of studies.[7][13]
2002	July 19	Early development	The Delhi Metro Rail Corporation, recognizing the imperative need for competency building in rail-based urban transportation systems, establishes the Delhi Metro Rail Academy at the Shastri Park Train Depot. Since its inception, the Academy would play a crucial role in training over 45,000 DMRC employees, contributing significantly to the organization's functioning.[14]
2002	December 24	New line	The Red Line, the inaugural line of the Delhi Metro, is inaugurated by then-Prime Minister Atal Bihari Vajpayee.
