     Note: In railway construction, the axle guard, or pedestal,
           with the superincumbent weight, rests on the top of the
           box (usually with a spring intervening), and holds it
           in place by flanges. The box rests upon the journal
           bearing and key, which intervene between the inner top
           of the box and the axle.
