A year after the inception of Amtrak, standards had begun to slip a bit. When George Horna shot the Super Chief at Chicago on June 19, 1972, the half-dozen leased Santa Fe F's were not only grubby, but lead F7A 310L was carrying an extra backwards curve on its Warbonnet paint scheme thanks to a replacement stainless steel panel donated by another unit. By November 1972, the extra curve on "Santa 310" had been scraped off and the proper striping and "Fe" had been added. Photo from the Vincent J. Porreca collection.
