Such signal bells stood at railway stations and signal boxes. They announced the arrival of a train, and the sound could tell from which direction it came. Both of them were allowed to stay, because the signal box in Heerbrugg was not broken off. It was made available to artists for exhibitions. In between you see the new residential and office building which is the subject of the poster in the previous photo. Heerbrugg station, Switzerland, May 11, 2010.
