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. Here is the 2-6-6-2 built for the Baltimore & Ohio Railroad, a KK-2 number 7450. According to the specifications listed on the back of the builder's card, this single expansion articulated locomotive had in working order, a total engine and tender weight of 739,000 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.
