USRA locomotives

Grand Trunk Western 5632 is a class K-4b 4-6-2 "Pacific" type steam locomotive built by the Baldwin Locomotive Works in November 1929 for the Grand Trunk Western Railroad.

Grand Trunk Western 5629 was a 4-6-2 K-4-a steam locomotive, which was a copy of the United States Railroad Administration's (USRA) Light Pacific design, built by American Locomotive Company (ALCO) in 1924, for the Grand Trunk Western Railroad. It was used to haul commuter passenger trains in Michigan until 1959 when it was purchased by Chicago-based railfan Richard Jensen for use in pulling several excursion trains in the Chicago area throughout the 1960s.

The Atlantic Coast Line P-5-A was a class of 70 4-6-2 USRA Light Pacific steam locomotives built by the American Locomotive Company's Richmond and Brooks Works between 1919 and 1920 for the Atlantic Coast Line Railroad and operated by the railroad until the early 1950s.

The USRA standard locomotives and railroad cars were designed by the United States Railroad Administration, the nationalized rail system of the United States during World War I. 1,870 steam locomotives and over 100,000 railroad cars were built to these designs during the USRA's tenure. The locomotive designs in particular were the nearest the American railroads and locomotive builders ever got to standard locomotive types, and after the USRA was dissolved in 1920 many of the designs were duplicated in number, 3,251 copies being constructed overall. The last steam locomotive built for a Class I railroad in the United States, an 0-8-0 built by the Norfolk and Western Railway in 1953, was a USRA design. A total of 97 railroads used USRA or USRA-derived locomotives.

The USRA Heavy Mountain 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 freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification.

The USRA Light Mountain 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 freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification.

The USRA Heavy 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.

The USRA Light Mikado 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 freight locomotive of the USRA types, and was of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification.

Baltimore and Ohio 4500 is a 2-8-2 "USRA Light Mikado" steam locomotive built by the Baldwin Locomotive Works in Philadelphia, Pennsylvania in July 1918 for the Baltimore and Ohio Railroad (B&O) as a member of the Q-3 class.
