The USRA 0-6-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light switcher of the USRA types, and was of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification.
A total of 255 locomotives were built under USRA control; these were sent to the following railroads:
After the dissolution of the USRA, the Atlantic Coast Line, Chicago, Burlington and Quincy, Chicago, St. Paul, Minneapolis and Omaha Railway, Gulf, Mobile and Ohio Railroad and Texas and Pacific Railway ordered additional copies of the USRA 0-6-0 design, while the Missouri Pacific Railroad and the Wheeling and Lake Erie Railway ordered only copies.
