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.
Confirmed by Guinness World Records[3], which credits BHP Iron Ore with running the record 7.353km train from the Newman/Yandi mines to Port Hedland on 21 June 2001.
Wikipedia's article on the Mount Newman railway line corroborates that BHP's Pilbara iron-ore railway between Newman/Yandi and Port Hedland is the line that set the world's longest-train record, consistent with the pin's account of the June 2001 run.
Guinness World Records' own record page states the longest train ever was 7.353km long with 682 ore cars and 8 locomotives, run by BHP Iron Ore in Western Australia on 21 June 2001, matching the pin's date and details exactly.
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.
