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.
Given as a target, not a fixed date, per the pin description: "…e Airport and the Parc des Expositions. Estimated date.…"
Rail Journal's own headline, "'Shock' delays for Grand Paris Express project," is consistent with Wikipedia's[1][3] account of schedule slippage, though a 403 error blocked retrieval of the text to confirm exact revised dates.
Wikipedia[1] states Line 17 will open in phases, with full completion "from Parc des Expositions to Le Mesnil-Amelot" targeted for 2030, matching the pin's stored estimated date, while noting the schedule has already slipped from an original 2024 target.
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.
