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. A total of 15 locomotives were built under the auspices of the USRA.

The USRA developed designs for 0-6-0 and 0-8-0 switcher locomotives, 2-6-6-2 and 2-8-8-2 Mallet locomotives, and both light and heavy versions of the 2-8-2, 2-10-2, 4-6-2, and 4-8-2 types.

Only 15 "Heavy" mountains entered service under the USRA aegis. Baldwin built two engines for the C&O, Alco-Brooks supplied three more to the C&O as well as 10 more to the N&W. LeMassena argues, however, that this particular design influenced not only 4-8-2 designs, but also encouraged the development of the larger 4-8-4.

The USRA produced standard designs for 0-6-0 and 0-8-0 switching locomotives, 2-6-6-2 and 2-8-8-2 compound articulated freight locomotives, and light and heavy versions of the 4-6-2 Pacific, 4-8-2 Mountain, 2-8-2 Mikado and 2-10-2 Santa Fe-type locomotives.

Louisville & Nashville 4-8-2 "Mountain" Locomotives in the USA The Louisville & Nashville Railroad took delivery of 16 USRA design 4-8-2s in 1926. These locomotives had 27 x 30 cylinders, 70" drivers, a boiler pressure of 200 psi, exerted 53,900 lbs of tractive effort and each weighed 334,240 pounds.

Heavy USRA 4-8-2s built by Alco's Brooks works in 1919 (K-2, 116-125) and Baldwin (K-2a, 126-137) in 1923. Baldwin's works numbers were 56138 in January 1923, 56279-56289 in March. Because they came four years later, the railway had some modifications to make to the original USRA design (Locobase 232).

2001年8月4日 · These locomotives were designed from the USRA 4-8-2 Light Mountain starting originally by ALCO in 1919. Even back then many parts were interchangeable with other NSRA type engines. Cylinders were 27" by 30" with drivers 69" in diameter. Boiler pressure was rated at 200 pi with a weight of 327,000 pounds and a tractive force of 53,900 pounds.
