Come May 29, travelling from Delhi to Gurgaon via Delhi Metro will just take 50 minutes. With inauguration of a new corridor on Delhi Metro Magenta Line, 16 new stations will be open to public connecting Janakpuri to Kalkaji. One of the prime attractions on this Magenta Line would be a 15.6 metre long escalator, which would be India's tallest. Metro officials say the escalator on Janakpuri West Metro station would be as tall as a five-storey building.
