HCW: An unprototypical pair

I typically post HCW's that are quite prototypical, but this time, I'm going to go unprototypical, by employing a Union Pacific SD-type locomotive.

Around 1 P.M. in the afternoon, two locomotives were spotted going up to the Horseshoe Curve. In lead was Union Pacific SD40-2 #3808, with PRR GP35 #2253 trailing behind. Both were hauling boxcars to Pittsburgh.
