Delhi Metro Golden Line: The Delhi Metro Rail Corporation (DMRC) has completed the construction of the second tunnel for the underground metro corridor on the Golden Line (Aerocity to Tughlakabad). The 1550 metre long tunnel is built from Kishangarh to Vasant Kunj on the Golden Line, which is under construction in Phase 4.
