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.
An Coimisiun Pleanala's[4] own notice of decision for Railway Order Application ABP-314724-22 (Metrolink - Estuary to Charlemont via Dublin Airport) carries the decision date 02/10/2025, and RTE[5] reported that day that "An Coimisiun Pleanala published the Railway order this morning which gives construction for the MetroLink Project the green light". The pin's milestone - the grant of planning permission - therefore has an exact day, 2 October 2025; the old date stood for the separate 2027 target for enabling works.
Engineering News-Record's own headline reports Ireland splitting the $18B MetroLink procurement into separate civil and rail systems packages, consistent with the pin's estimated 2027 start date, though the page itself could not be fetched to quote directly.[1]
The Irish Times confirms Minister Darragh O'Brien's statement that MetroLink "enabling works" could start in 2027, in an article dated 3 October 2025 that also reports planning permission was granted the day before - consistent with the pin's estimated 2027 target date.
The deciding body's own notice gives the decision date as 02/10/2025, which is the day the pin's milestone happened; nothing else pins the grant of the Railway Order to a day.[1]
RTE, publishing on 2 October 2025, reports that "An Coimisiun Pleanala[4] published the Railway order this morning which gives construction for the MetroLink Project the green light", independently dating the approval to that morning.
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.
