This beautiful, streamlined T-1, Pennsylvania Railroad number 5533, was built in 1946 by Baldwin Locomotive Works, where my great, great Uncle Robert F. McKee, Sr., worked as a design engineer. He only gave my father two Pennsylvania T-1 builders photo cards, the 5533 and the 6110. When my father would travel as a young boy to visit his great Uncle Rob, Uncle Rob would give him some of these Baldwin Locomotive Works builders photo and specification cards, and my father had quite a collection. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
