Delhi Metro Rail Corporation’s first ever stretch was inaugurated on 24 December 2002 by the then Prime Minister of India Atal Bihari Vajpayee. The first installation was 8.3 km and it ran between Shahdara and Tis Hazari.
Construction of the DMRC began on 1 October 1998 with funding mostly coming from Indian public funds and a Japanese loan.
By 2011, the Phase 1 and Phase 2 of the Delhi Metro was fully operational. They comprise 6 lines, namely, Red, Yellow, Blue, Green, Violet and the Airport Express line (Orange). The Phases were opened to the public on 25 December 2002 and 3 June 2008 respectively and by November 2016 and August 2011, they were completely operational.
The Red Line, Yello Line and Blue Line are the part of Phase I. While Phase II was formed with extending the three lines further and introducing three new lines, Orange, Violet and Green.
The Phase III, on which the construction started in 2011 brought 2 new lines to the Delhi metro; Pink and Magenta. Extensions on a near dozen existing lines also took place. The completion of this phase is expected to complete by 2018.
The construction of Phase IV has recently been approved and as it stands today, the completion could take up to 2024. Another new line, Indigo, is said to be introduced. The Delhi Metro is India’s second oldest metro after the Kolkata Metro and with a spread of more than 300 km, it is among the top ten longest metro systems of the world.
