It is late 1949 and a local amateur photographer was near the Pennsy yard and decided to take some photos of switchers doing their job. He was looking for his favorite subject, steam switchers, but he did not see any this day. Very unusual since the Pennsy still had mostly steam switchers on their roster. He did catch a FS10, BS10, and a GS4. The little GS4 was working hard moving a string of reefers to the icing track.
