Delhi Metro begins train services at 6:00 AM on Sunday, September 13, 2026, across all lines, to help candidates reach exam centres for the National Defence Academy (NDA) and Combined Defence Services (CDS 2) examinations. The decision is aimed at ensuring candidates can arrive before reporting and entry deadlines, while also supporting general passenger movement on the day.

Metro services on Sundays typically start later on some corridors, including the Pink, Magenta and Grey lines at 7:00 AM. Delhi Traffic Police and DMRC coordinate the change after a CDS aspirant raised concerns about availability of early morning travel. Media reports also note that traffic and operational planning around the BRICS Summit may have been a factor. Candidates are advised to check reporting times and instructions on their admit cards, plan for additional travel time, and carry a printed e-admit card and valid photo identity for verification.
