I've assembled the back page scans. These scans are informal and low-res, intended for review. I'll have them redone as high-res. You can see the power line at the bottom of the picture. The positions of people on the track exactly match their positions on page 41 of my document, so this is a wider-framed version from the same exposure. Page 70 of my document shows the terrible quality that came from the Trib microfilm.

Note that it shows the right wing breaking off at the tracks. In my opinion, the break should be shown between engines three and four. I suspect the reporter conveyed the CAB story to the artist wrong, but having worked at a newspaper I can attest that it's sometimes more important to be finished than to be correct.
This is the same image which under higher resolution shows a large object on the tracks, but no large object was there by the time a photographer got to the tracks.
