Chesapeake & Ohio 4-6-2 No. 464 receives a good washdown in this photo of unknown origin furnished by Tom Rock of T.D.R. Productions. This engine belonged to the C&O's class F-16, built by Baldwin Locomotive Works in 1913. These Pacifics had 73-inch drivers and 27x28-inch cylinders, and sustained a boiler pressure of 185 p.s.i. Their grate area measured 60 square feet, while their evaporative heating surface totaled 3785 square feet and their superheater surface 880 square feet. Weighing 290,000 pounds minus tender, they developed 43,950 pounds of tractive effort. No. 464 displays the typical appearance of C&O steam locomotives erected in the earlier decades of the twentieth century, with the air pumps hung on the front of the smokebox, the headlight mounted just above the pilot, and the Vanderbilt tender. The location of this terminal is unknown, but the date is prior to 1943-44 when the C&O started using number boards on the smokebox front; they would have appeared on either side of the bell. The locomotive in the background is C&O K-3-A 2-8-2 No. 2336.
