In the 1847 station, bells rang before each departure of the Spanisch-Brötli-Bahn. The signal order prescribed as follows: "10 minutes before the departure of a train, one [bell]; 5 minutes before the same, two [bells]; and immediately prior to departure, three bells". For the 1871 renovations, the architect Jakob Friedrich Wanner gave the station clock the place of honour in the portal above the main entrance, and the bells were placed in a small tower in the east facade.
