I have enjoyed all the comments about the views of McKeesport. I have lived in the Pittsburgh area my entire life. My understanding is that the B&O tracks that sliced through the heart of McKeesport were quite a problem, especially with regard to traffic. As a result, the B&O was rerouted onto the P&LE which ran by the edge of town (along the Monongahela River) in the early or mid 1960's (1964 I think?). Once completed, the B&O tracks in downtown McKeesport were removed. I assume work was done on the P&LE as well...the bridge carrying it over the mouth of the Youghiogheny River as it spills into the Mon is of relatively modern construction given its lack of lacing bars and the prescience of oval cut outs in the girders.
I would have only have been around 8 years old at the time, and never got to that area until I started driving in 1972, but I've heard many stories about it from the old time model railroaders around here who saw it first hand.
Presumably, this photo shows the removal of the tracks once the relocation was completed.
