The USRA Light Santa Fe 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 . These locomotives were of 2-10-2 wheel arrangement in the Whyte notation , or 1′E1′ in UIC classification ; this arrangement was commonly named "Santa Fe" in the United States . At the time, the Santa Fe was the largest non-articulated type in common use, primarily in slow drag freight duty in ore or coal service.
A total of 94 of these locomotives were constructed under the auspices of the USRA. They went to the following railroads:
