NOT MY VIDEO, BUT USED WITH PERMISSION.
Just west of Pittsburgh, in Leetsdale's Buncher Industrial Park, lies one of Pittsburgh's more unique rail operations. MOL-DOK is a transload facility on the Ohio River that primarily loads and unloads barges and NS coal trains. The facility uses an ex-Reading SW900M to shuffle cars around the tight confines of the park and NS's mainline. Though I have not had the courage to visit it myself, a high schooler (NS 5350 on YouTube) who lives in the area and with whom I am friendly, has become a fixture at the site, documenting several of their moves and even got a cab ride. This is the most thorough of his recent videos. Of particular interest is the spaghetti bowl of diamonds that mark the facility.
