Detail of the freight car K 411 of the Wengernalpbahn seen in Wengen on 20
March 2002. A cogwheel for braking is at the axle next to the "lower" end. Next
to it are two drums on which the brake shoes work. I think the cogwheel and the
drums are not coupled with the axle, as the running wheels have a bigger
diameter than the cogwheel.
