Otis traction glass elevator at a pedestrian bridge in Bonn

Between the light rail stations Ollenhauserstraße and Olof-Palme-Allee in Bonn, there is a pedestrian overpass which crosses a street and the light rail tracks. Those seperate the street into two one-way streets with two lanes each. In the video, a light rail train passing by is shown.
The elevators are Otis GeN2 systems using belts rather than steel cables. Oddly, they take quite a while to level.
