If you are at the railway station in Olten, Switzerland, at the full hour you might hear a bell but as usual railway stations are quite noisy many people don't notice it.

The piece listed here can be found on platform 3 in the middle of the main building attached to the roof. I didn't find an official name of the piece and I have no idea when it was made. But I remember that it was there many years ago (as far as I can remember).

And if you want to see it in action don't forget to be there at the full hour. It will only run a few minutes.
