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 4-6-4 built for the Milwaukee Road, number 6400. It had a tractive force of 45,820 lbs., and a total engine and tender weight of 665,000 lbs. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
