[PRCo] Castle Shannon slum???

[Fred Schneider]

This link leads to an abandoned mining patch story in the Pittsburgh Press ("50 Heath Law Violations….") in the postwar period at Castle Shannon.   Pittsburgh Terminal Coal Company sounds like a subsidiary of Wabash-Pittsburgh Terminal Railroad, i.e. the Pittsburgh and West Virginia.   The earlier maps show they did own Mine 7 down at Washington Junction.  However, I have no clue that it was in Castle Shannon borough in 1947 … it was not 40 years earlier.

Anyone knowledgeable enough to tell me what this refers to in todays terms?
