The beginning of the rack section at the exit of the station Lauterbrunnen of
the Berner Oberland-Bahn seen on 18 March 2002. I do not know what this first
flat rail at the beginning is for. Then comes a movable rack where even the
teeth seem to be movable, followed by the normal rack. At the second track in
the background, the movable part of the rack seems to have fixed teeth.
