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.
Happened as dated, per the source: "Brightline West[4] officially broke ground on April 22, 2024, on the nation's first true high-speed rail system." Completion: Brightline West PR director Antonio Castelan to Equipment World[2], 18 Feb 2026: the project's "formal completion date is now late 2029" (end = end of 2029).
The owner's spokesman confirmed the formal completion date moved to late 2029 (from the 2028 Olympics target), with cost now $21.5B. Year-level ('late 2029'), so endDate null.[1]
Railway Technology corroborates that "the ground-breaking ceremony for the project was held in April 2024," matching the pin's stored date.
Brightline West's own press release confirms it "officially broke ground... on April 22, 2024" on the Las Vegas-to-Southern-California line, matching the pin's stored date 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. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
“218-mile system”
Many city pairs are too short to fly and too far to drive.
How: A 218-mile, 200 mph high-speed rail line in the middle of I-15 connecting Southern California and Las Vegas in about two hours, almost half the time of driving.
