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.
Date has passed, but interestingengineering.com does not confirm it happened then; unverified.
RailwayPro quotes SNCF's CEO pledging the company 'will become the first in the world to put into service an autonomous train on a high-speed commercial rail line,' targeting service by 2023 - matching the pin's stored January 2023 date, though as a 2018 aspiration rather than a confirmed launch.
CGTN similarly reports SNCF's goal of autonomous TGV trains 'by 2023' with trials starting in 2019, corroborating the pin's stored date as a target rather than a verified outcome, consistent with the pin's 'unknown' confidence.
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.
