Thanks for your kind appreciating views. However, DMRC has already recommended the proposed link between Huda City Centre & Dwarka Sec 21 ( via Iffco Chowk, Maruti Udyog & Palam Vihar )as an extension of the Highspeed Delhi Airport Metro express line connecting GGN with NDLS within 30-35 mins.This proposal only can ease out the traffic congestion on DEL-GGN corridor in future. No idea about linking GGN rly stn with metro.
