The New Haven operated a total of 35 of the original USRA 0-8-0 design. All were built by ALCO-Schenectady, 15 in 1920 and 1923 directly for the New Haven and 20 in 1922 originally for the Chicago & North Eastern. The specs given in the diagrams of the operator differ a bit from the original USRA diagrams, most notable a boiler pressure of 190 instead of 175 psi. The firebox surface given below contains three arch tubes with a total area of 18 square feet. They were retired between 1949 and 1952.
