Delhi Metro resumed services on all routes with the reopening of Airport Express Line on Saturday after a hiatus of over 170 days due to the coronavirus pandemic. All corridors of Delhi Metro network are now running with the original timings being followed from the pre-pandemic schedule of 6 am to 11 pm.

"With the resumption of service on the Airport Express Line, all lines of the Delhi Metro network are now open! Remember to follow the guidelines when travelling. #MetroBackOnTrack," the Delhi Metro Rail Corporation (DMRC) tweeted.

This comes days after Delhi Metro restarted operations with the Yellow Line after being shut for over 5 months. The Metro services were shut on March 22 to contain the spread of the novel coronavirus.

The Ministry of Home Affairs had recently issued guidelines allowing the Delhi Metro to resume operations in a graded manner, following which the DMRC had said it would be done in three stages from September 7-12.

Under stage one, Yellow Line or Line 2 and Rapid Metro were made operational with restricted service hours. Stage two kicked in from Friday with extended service hours, and stage three came into effect from Saturday onwards with Metro services going back to pre-COVID-19 time schedule of 6 am to 11 pm.
