CR 8054, CR 8093, CR 8267, CR 6499 Horseshoe Curve 1990

I forget now if this was a light engine movement or just a weird consist for lugging freight around Horseshoe Curve, but in 1990 I caught GP38-2s 8054, 8093, and 8267, SD40-2 6499, and it appears others rounding the Curve from a parking lot vantage point. It is interesting that in 1990 the view is tree-free and I was recently reading that after much money and effort it is again tree-free in late 2016.
