The 12.64-km long Magenta line will link south Delhi's Kalkaji and Noida's Botanical Garden. The Botanical Garden Station has been developed as the Metro's first-ever inter-change station outside Delhi. Once the entire corridor from Botanical Garden till Janakpuri West (38.23 km) is opened, commuters from Noida will be able to go to Gurgaon by changing trains at Hauz Khas.
