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 2-10-4 steam locomotive, number 634, was built for the Bessemer & Lake Erie Railroad. According to the specifications listed on the back of the builder's card this engine had a total weight of 820,200 lbs., and a tractive force of 96,700 lbs. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
