On December 5, 2014, my brother and I, stood on the platform at Overbrook, Pennsylvania along the former Pennsylvania Railroad Main Line.

Working with my Canon EOS 7D, I exposed this photo of an approach medium aspect on an old PRR position light signal. At left, Amtrak’s westward Pennsylvanian—train 43—glides toward the station behind P42 number 71.

I made a host of minor modifications in post processing aimed at improving the camera RAW file.
