Chennai Metro Trial Run to Begin Between Koyambedu and Nandambakkam in November
Phase-2 Corridor 2 trial operations between Koyambedu and Nandambakkam are expected to begin in November 2026, bringing metro service closer for West Chennai commuters.
Why this matters to Tamil Nadu
For commuters in West Chennai — particularly residents of Virugambakkam, Vadapalani, Ashok Nagar, Alandur, and the Poonamallee road belt — the Koyambedu–Nandambakkam stretch is the first Phase-2 segment to reach trial stage, giving a concrete timeline for when metro connectivity arrives in areas currently dependent entirely on congested bus routes. Trial runs precede commercial operations by 6–12 months depending on safety certification; this means West Chennai residents could see operational metro service in mid-to-late 2027.
