This is the Denver & Rio Grande's narrow gauge pile driver OB set up in the operating position as if it
were driving a piling off the end of the track without lettering (by request). This is animated with sound effects. Surveyor
will not allow you to place this car far enough toward the end of a track. This can be overcome by adding a short section
of invisible track at the end. This allows the hammer to be off the end of the visible track.
