The 8.4-km stretch is planned as the initial section". December is the last month of the year the pin already sat on, so the day stands at 31 December 2026 - now as the end of a named month rather than a bare year. The full Aerocity-Tughlakabad corridor follows later.
The first 8.4 km section of the Phase 4 Golden Line, from Tughlakabad to Sangam Vihar, is targeted to open in December 2026; the rest of the 29.785 km Delhi Aerocity-Tughlakabad corridor, 19 stations with 12 of them underground, follows in phases. By April 2026 civil work was 78 per cent done with five tunnel boring machines still at work, and trainsets had begun arriving at the modified Sarita Vihar depot.
