Phase 1 (253 km, 179 billion baht) began construction on 21 December 2017 and was only 52.4% complete as of March 2026; it was originally due in 2026 and slipped to 2027 before the current target[2]
Phase 2 (about 357 km, about 341 billion baht) was approved by the Thai Cabinet on 4 February 2025, with operations expected in 2031[2]

已延期延期2年可信度 61%99天后Construction World[2], 16 September 2026, narrows the year to a month: DMRC is "targeting December 2026 for the opening of the first operational section of the Golden Line between Tughlaqabad and Sangam Vihar. 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.

The first stage of Singapore's fully elevated, driverless Jurong Region Line opens, serving Tengah and the western estates around Choa Chu Kang. LTA pushed the opening back by about six months after viaduct construction over the Pan-Island Expressway could only be carried out during overnight road closures, and will run interim shuttle buses from end-2027 until the line opens.
