ThyssenKrupp's own press release states "In 2020, MULTI will be installed at the Eastside Tower in Berlin for the first time," matching the pin's stored late-2020/early-2021 date, though as of its October 2017 publish date the system was still undergoing testing.[1]
Dezeen's own headline and July 2017 publish date report ThyssenKrupp unveiling its ropeless MULTI elevator system - an earlier unveiling than the Berlin installation itself, consistent with but well predating the pin's stored 2020-2021 installation date, though the page itself could not be verified directly.
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.
