Explanation: The Delhi Metro is a rapid transit system that serves the National Capital Territory of Delhi and its neighboring regions. It is a significant part of the public transportation infrastructure in Delhi, providing a reliable and efficient mode of transport for millions of commuters daily. The history of the Delhi Metro dates back to the late 1990s when the Delhi Metro Rail Corporation (DMRC) was established to plan and construct the metro system.
The planning and construction phases of the Delhi Metro began in earnest in 1998, with the first phase of construction starting in 2000. However, the actual operations of the Delhi Metro did not commence until December 24, 2002. This date is significant as it marks the official launch of the metro system, with the first line connecting Shahdara to Tis Hazari. The opening of this line was a major milestone in the transportation history of Delhi, providing a modern and efficient alternative to the existing modes of public transport.
The Delhi Metro has since expanded to cover a vast network, with multiple lines and stations serving various parts of Delhi and its neighboring regions. The system has grown to become a crucial part of the city's infrastructure, contributing significantly to the reduction of traffic congestion and air pollution. The metro system has also been recognized for its innovative features, such as the use of regenerative braking technology and solar power, which have helped to make it one of the most sustainable public transport systems in the world.
Understanding the start date of the Delhi Metro is important for students of Delhi General Knowledge (GK) as it provides a key historical reference point for the development of the city's transportation infrastructure. It is also relevant for those preparing for competitive examinations that include questions on Delhi's history and development. The correct answer to the question is 2002, as this is the year when the Delhi Metro began its operations, marking the start of a new era in public transportation in Delhi.
