 The Red Line was first line of the Metro to be opened and connects Rithala in the west to <unk> Garden in the east , covering a distance of 25 @.@ 09 kilometres ( 15 @.@ 59 mi ) . It is partly elevated and partly at grade , and crosses the Yamuna River between Kashmere Gate and Shastri Park stations . The inauguration of the first stretch between Shahdara and Tis Hazari on 24 December 2002 caused the ticketing system to collapse due to the line being crowded to four times its capacity by citizens eager to have a ride . Subsequent sections were inaugurated from Tis Hazari – <unk> ( later renamed Inderlok ) on 4 October 2003 , Inderlok – Rithala on 31 March 2004 , and Shahdara – <unk> Garden on 4 June 2008 . The red line has two interchange stations , the first Kashmere Gate with the yellow line and the second Inderlok with the green <unk> from 24 November 2013 six coach trains will be inducted in a phased manner in red line .
