Chesapeake & Ohio 0-8-0 switcher No. 120 represents the C-15 class (originally C-15a) that came from Baldwin Locomotive Works in 1929. They had 51-inch drivers, a boiler pressure of 185 p.s.i., and cylinder dimensions of 25x28 inches. Weighing 228,340 pounds, they mustered 53,950 pounds of tractive force. August A. Thieme of Richmond, Virginia captured this view of No. 120 at Richmond at an unspecified date, perhaps not long before the retirement of this group of engines by 1953.
