The United States Army Transportation Corps S160 Class is a class of 2-8-0 Consolidation steam locomotive designed for use in Europe during World War II for heavy freight work. A total of 2,120 were built and they worked on railroads across the world, including Africa, Asia, all of Europe and South America.

During the 1930s, the United States Army Transportation Corps approved update of a Baldwin Locomotive Works World War I design in contingency for war transportation, to create the S159 Class. During the period of World War II when America was neutral, the government of Franklin D. Roosevelt approved the Lend-Lease supply to the United Kingdom of the S200 Class, designed specifically to fit into the restricted British loading gauge.

With America's entry to World War II, the USATC needed a developed design from which to create a volume of locomotive power for the wrecked railways of Europe, which they could use to deploy military hardware and civilian goods. Hence the design created by Maj. J. W. Marsh from the Railway Branch of the Corps of Engineers learnt from both previous locomotives, designed on austerity principles and built using methods which created efficient and fast construction speed over long life, such as axlebox grease lubricators and rolled plates preferred to castings.

With cast frames and cast wheels, the front two driving axles were sprung independently from the rear two driving axles to allow for running on poor quality track. The larger tender layout was derived from the similar design for the WD Austerity 2-8-0, with the coal bunker inset above the water tank to improve visibility when running backwards.
