My great, great uncle Robert F. McKee, Sr., was a design engineer at Baldwin and he would give my father different Baldwin Locomotive Works builder's cards when my father would visit him in Collingswood, New Jersey. This beautiful 4-8-4 Northern, number 4521, was built for the St. Louis - San Francisco Railway (Frisco). According to the specifications listed on the back of the builder's card, this engine and tender had a total weight of 754,700 lbs., and it had a tractive force of 71,200 lbs. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
Dedicated to my father, John R. Doughty, Sr., and to his great uncle, Robert F. McKee, Sr., who worked at the Baldwin Locomotive Works as a senior design engineer, including working on the design for the Duluth, Missabe & Iron Range 2-8-8-4 Yellowstones
