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 2-10-4 built for the Chicago, Burlington and Quincy Railroad, number 6325. It had a tractive force of 90,000 lbs., and a combined engine and tender weight in working order of 897,400 lbs. This Baldwin Locomotive Works builders photo specification card is from the John R. Doughty collection.
