In September of 1949, the Baldwin Locomotive Works built its last domestic steam locomotive, the No. 1309 "Mallet." Ironically, the "Mallet" was one of the last types of steam locomotives retired when diesel-electric engines entered the arena, yet its design dated back to the late-19th century. Anatole Mallet created the first 0-4-4-0 type compound engine in 1885 for the tightly curved tracks in Bayonne, France. The design first appeared in the United States when ALCO constructed a 0-6-6-0 compound "Mallet" for the B&O in 1904. The engine was described as "compound" because it used the steam twice; first for the rear set of high pressure cylinders, and second for the low pressure front cylinders. It was changed in 1910 by the C&O, their version of the 2-6-6-2 compound "Mallet" was even more capable of hauling heavy coal drags around tight curves.
The No.1309 worked out of the C&O's Peach Creek terminal in Logan, West Virginia for coal transportation and shifting hoppers back and forth. In 1956, the No. 1309 retired from service as one of the last locomotives built for the C&O. It remained in the Peach Creek Terminal Roundhouse until 1972 when the No. 1309 was transferred to the Baltimore & Ohio Railroad Museum.
