The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
A target, not a fixed date: Railways Minister Ashwini Vaishnaw told the Lok Sabha on 23 July 2025 that the full 508 km corridor is to be completed by December 2029, and reports in September 2026 still gave December 2029; the first section is due on 15 August 2027. Dated to the end of December 2029.
Added when correcting this pin: The official target for the full line is December 2029 (minister's Lok Sabha reply, 23 July 2025, repeated September 2026); 15 August 2027 is only the first section. The line was first due in 2023 per Wikipedia[1], so it is marked delayed from 2023-12-31. Month-only target dated to the month's last day per the house convention.

India's official government news service reports Railways Minister Ashwini Vaishnaw's statement that the first section (Surat-Bilimora) starts service on 15 August 2027, with the full Mumbai-Ahmedabad corridor phased in through 2029; left without an exact day since sources disagree on which milestone counts as the full corridor 'opening'.[1]
Deccan Herald, a major Indian daily, independently corroborates the government's phased timeline: first section in 2027, full Mumbai-Ahmedabad corridor by 2029.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
