International Railway Journal reports Deutsche Bahn's CEO told the supervisory board the December 2026 phased opening date is no longer achievable; no replacement exact date has been set, so the pin's stored December 2026 date is now known to be wrong even though a precise new date isn't yet fixed.[1]

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.
