Delhi Metro services will commence early at 4:30 AM tomorrow from all terminal stations across the DMRC network, instead of the usual 6:00 AM. Trains will operate at 15-minute intervals on all lines until regular revenue services begin as per the day’s scheduled timetable. The special arrangement has been made to facilitate the smooth movement of devotees observing the Usha Arghya ritual on the occasion of Chhath Puja.
