USRA Light 4-6-2 was the standard light passenger locomotive of the USRA types, and was 4-6-2 wheel arrangement in the Whyte notation, or 2′C1′ in UIC classification.
A total of 81 locomotives were built under USRA control that were part 3 railroads. 45 were sent to the Atlantic Coast Line Railroad which were P-5-A class and included road numbers from 1500 to 1569 (25 copies). 30 were sent to Baltimore and Ohio Railroad and were classed as P-5 with road numbers from 5200 to 5229. 6 were sent to the Louisville and Nashville Railroad which were classified K-5 with road numbers 240 to 245 (20 copies).
