The BVG is the heart of Berlin – so what would happen if this heart suddenly stopped? On 29 September, World Heart Day, the whole BVG paused for a moment. At exactly 8am, all of the passengers in the trains, busses and metros stopped for a powerful message that came from the heart.

A real organ donor addressed all passengers via a video announcement and appealed to them to become a potential organ donor. Another film was created to inspire millions of people more online.
