On Tuesday morning, the Magenta Line of the Delhi Metro, running past several neighbourhoods of south Delhi and linking Noida and Gurugram, finally became operational.

With the formal inauguration (video above) being conducted on Monday, the 26.4-km stretch also put the domestic terminals of the Delhi Airport on the Metro line for the first time. (The international terminal, or T3, already had its own Airport Express line.)

Ever since the original “Metro Man of India”, E Sreedharan – who ensured that the early phases of the Delhi Metro were rolled out on schedule – retired, there have been long delays in opening various lines. Still, with the Magenta Line now complete, Delhi is far and away the best-connected city in India when it comes to this form of public transport, with increasing portions of the enormous metropolis being added to the map.
