The Santa Fe Railroad ordered fifteen 2-8-4 Berkshires from the Baldwin Locomotive Works in 1927. These locomotives were designated as Class 4101 and assigned road numbers 4101 through 4115. The Class 4101 "Berkshires" had 63" diameter drivers, 27" x 32" cylinders, boiler pressure of 220 lbs and could exert a tractive effort of 69,200 pounds. They were all retired and scrapped by 1955. This image, from the A. B. Johnson collection, was taken at the engine terminal in Kansas City.
These locomotives were almost unknown by the railfan community and were rarely photographed. They spent most of their lives working in the midwest.
