I remember the thread from a couple of years ago, but don't know the exact info that was there. What I remember mostly was the smaller pipe bundles when I was there. I only have images from 1968 scanned, and really only have the one train with loads...478 to Farmington. Here are a couple of images that might show something for you.

I attached these out of order...The last scene at the bottom comes before the first shot south of Carbon Junction. I picked these cause you could see more of the train from an elevated position. The other shot is at Aztec. For what it is worth, this was the first delivery of 1968 to Farmington by train.
