There is little I can see to tell us where this yard is

As Eric said, the answer is in the descriptive info. There's a bit more info, (and more photos) if you go to the actual Cornell site:

   Title:   Rutherford Yards   Collection:  U.S. President's Railroad Commission Photographs   Set:   Reading Railroad: Rutherford Yards and Steelton Industries   Date:   1960   Site:   Harrisburg, PAYou can use the links to see the entire set or the whole collection.  The photos in the collection are generally well identified, as they were evidence in a labor dispute.Jack Mullen
