Robert Graham of St. Paul, Minnesota snapped this image of K-5b No. 4933 somewhere on the "Big Four" before her 1936 renumbering from CCC&StL No. 6533. American Locomotive Company delivered this engine in 1927 as Pittsburgh & Lake Erie No. 9237. She was transferred to the Big Four in 1931 was dropped from the NYC roster and scrapped in 1952. These K-5s were the last 4-6-2s delivered to the New York Central System before the appearance of the Hudson type. They had a grate area of nearly 68 square feet, 3952 square feet of evaporative heating surface, and 1158 square feet of superheating surface; for other dimensions see the commentary on No. 4907 preceding. The K-5s were the last steam locomotives delivered to the NYC system to use the Walschaerts valve gear throughout their careers. The first class J-1 4-6-4s were built with the Walschaerts type but were subsequently converted to the Baker type, and nearly all subsequent NYC orders for steam engines specified the Baker gear. The advantage of the Baker gear is that all parts connect via pivots, whereas the Walschaerts type has an expansion link that is considered more prone to wear.
