Subway Rapid Transit systems in India

The Delhi Metro is a rapid transit system serving Delhi, Gurgaon, Noida and Ghaziabad in the National Capital Region of India. The network consists of six lines with a total length of 189.63 kilometres (117.83 mi) with 142 stations of which 35 are underground. It has a combination of elevated, at-grade and underground lines and uses both broad gauge and standard gauge rolling stock.

 Planning for the metro started in 1984, when the Delhi Development Authority and the Urban Arts Commission came up with a proposal for developing a multi-modal transport system for the city. The Government of India and the Government of Delhi jointly set up the Delhi Metro Rail Corporation (DMRC) in 1995. Construction started in 1998, and the first section, on the Red Line, opened in 2002, followed by the Yellow Line in 2004, the Blue Line in 2005, its branch line in 2009, the Green and Violet Lines in 2010 and the Delhi Airport Metro Express in 2011.

 Namma Metro (Our metro), also known as Bengaluru Metro, is a rapid transit rail system for the city of Bengaluru, Karnataka, India. The agency responsible for its implementation is the Bangalore Metro Rail Corporation Ltd (BMRCL). The first stretch between Baiyyappanahalli and M.G. Road was inaugurated on October 20, 2011.
