In 2007 and 2008, it was reported that small pieces of glass had fallen onto the street from cracks in the façade. This was followed by a near-fatal incident in 2016 in which a pane of glass measuring 30 by 150 cm (1 by 5 ft) fell onto a car on the street below.[2]
The original owner of the skyscraper was Sony as part of the wider Sony Center. In February 2008, Morgan Stanley and others bought the Sony Center with the tower for €600million.[3][4] In 2007, Deutsche Bahn had planned to move to a new headquarters built by Danish company 3XN outside the Berlin Hauptbahnhof,[5] although this fell through and Deutsche Bahn extended its Bahntower contract.[4][6]
When Morgan Stanley's real estate funds came into difficulties they sold their stake to South Korea's National Pension Service in 2010.[7]
In 2016, the Bahntower was featured in the Berlin skyline scene, which is part of the Lego Architecture series.
