Model railroading at 12" to the foot scale. Looking every bit like some of the over/under arrangements that are common on basement model railroad layouts, Grand Canyon Railway #29 comes cruising under the BNSF overpass at the north end of the Williams Yard, just as an eastbound freight charges overhead.
The Grand Canyon Railway is an old Atchison, Topeka and Santa Fe Railway branch line, so it should not surprise viewers that multiple main lines of the present-day BNSF run right through the Williams Yard. This particular overpass, just north of the GCRX shops has two tracks and is extremely busy. So when the 2019 Trains Magazine Charter attempted to set up an over/under shot including the #29 on her last day in service, it wasn't difficult to do. For this particular shot, the 29 was staged in position, and a freight was there literally within a minute or two. Just moments later, the 29 backed up for a higher speed run-by, and another freight came charging past just as she came through the tunnel, this time on the far track, going westbound. Although the bottoms of the wheels on the BNSF units weren't visible, the serendipitous timing amazed everyone. During the day, freights seem to pass over this bridge about every 5-10 minutes.
