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 2-10-4, number 6312, was built for the Chicago, Burlington & Quincy Railroad. According to the specifications listed on the back of the builder's card, this engine and tender had a total weight of 879,900 lbs., and it had a tractive force of 90,000 lbs. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
