The old elevated Pennsylvania Railroad elevated freight line avoids 30th Street Station passenger trackage and is one of several ways of routing freights through Philadelphia.
Historically this was an electrified route and although the catenary was removed during the Conrail -era after it ended electric freight operations.
I was inspired by the photography of Jonathan Smith who is a regular Tracking the Light follower and University of Pennsylvania professor, and has forwarded a variety of images of this line to me.
Operations on this line are sporadic, which can make photography difficult for infrequent visitors.
During my visit last week, I was short on time, and only had a few minutes to wait. I spent a few minutes inspecting different angles on Walnut Street, while hoping to hear a train.
Fortunately, just as I was getting ready to leave I heard the unmistakable roar of EMD diesels. So, with Lumix LX-7 in hand, I exposed these views as it rolled southward across the viaduct.
I adjusted the files using Lightroom to alter contrast. Specifically, I lightened the shadows, and tempered the highlights while slightly tweaking overall contrast.
The silhouetted views required more post-processing work since the lighting was more contrasty and I wanted to retain detail in both shadows and highlights.
