In the first photo, your looking to the SW. In the very bottom right runs a little bit of "Main St.". The next over street is "Broadway" The stack of "Downtown" buildings still stand. If you follow the tracks past the water tower and the depot, up at the top to the left of the rail line just as it goes out of the frame, I believe are the stock pens. I have not ben able to find a decent photo of them yet. And just off of the top would be the start of the "WYE". This photo appears to have been shot in the 50's
The Aerial view (second photo) is of the ElPaso pipe yard. The view is looking to the East. The yard is still in use today ( not by ElPaso ). Today the areas that are not in use in the 1956 photo, are actually in use today. Though there isn't that much pipe on the ground right now. This view, my friends is the ultimate reason that we have the D&S and the C&T today. The Farmington pipe boom saved all the K's that we so dearly love. Otherwise the abandonment would have happened much much earlier, And there may not of been the "Friends" to save the C&T and the tourists to keep the D&S running.
