Bob, in this cropped 126 image the pot is visible just beyond the switch immediately in front of my engine.  The white object is a stone bridge pier.
 
In the other view, shot from #21, a feature, possibly unique to Oregon, is that a westward diverging move is controlled by a pot signal also.  The elements demanding this unusual method of signal arrangement were viewing distance and clearance considerations.  In order for the signals to be visible to the Engineer of a westward move they had to be placed closer to the track than standard plans called for.  In fact, the clearance was so limited that only half of the roundel on the high signal was used.  An O5, while rounding the curve, was in danger of loosing its Engineer-side Clear-Vision wind screen if the screen was not folded in at this location.
 
All-in-all, this was a poor location for a siding switch and signal due to the extreme restrictions imposed by the bridge.  One other location with a non-standard signal installation was the east end of Milledgeville.  This signal arrangement was also dictated by the visibility requirements of westward trains.
