33156-33158 (January 1909) and 33181, 33187-33188 (February 1909).
The Clinchfield favored larger freight locomotives and had a disproportionate number of articulateds to handle the long coal drags that were the railroad's mainstay business. There were shorter, lighter freights to handle, though, and the Clinch bought this batch of Consolidations as its largest single purchase ever soon after the railroad opened under the CC & O banner. Equipped with a sizable boiler, medium-sized drivers for a 2-8-0, and 12" piston valves, the class remained essentially unchanged throughout its career.
Two were sold -- 314 in October 1937 to Sloss Sheffield Steel Company as their #28, and 309 in May 1941 to American Rolling Mill Company. The others were scrapped in July 1951 (312), December 1951 (300-303, 307-308, 310-311, 313), and September 1953 (304-306)).
