Is anyone home in Sarnen, Switzerland?

I once went past Sarnen, Switzerland on a train. It looked like a stereotypical rustic Swiss village at first sight in spite of the fact that none of the buildings seemed to have any paint on them. It was tempting to want to get off the train; however, I was overcome by the feeling that anyone who got off the train in this place might never see another train come along to get him or her out of it. It is supposed to be, at least near, the home of the Bio-Familia muesli company, yet, like some other places in Switzerland, it had no sign of human habitation.
