Скачать

In 1919, the Northern Pacific received four USRA standard 0-8-0 switchers from ALCo-Brooks. Designated as the G-1 class, they were numbered 1170-1173. Twenty copies of the original USRA switcher design were ordered from ALCo-Brooks in 1920, forming the G-2 class. The NP's original G Class switchers were rebuilt from older F Class 2-8-0s and were all retired by the late 1930s. Both the G-1 and G-2 classes ran until the end of steam on the Northern Pacific in the late 1950s.

During the first World War, the United States government put the nation's railroads under the control of a government agency: the USRA (United States Railroad Administration). The lasting legacy of the USRA was a group of standard locomotive designs, which were used by railroads across the country. The locomotives were designed to use a minimum of materials to conserve vital materials for the war effort. To serve as many roles as possible, the USRA created a set of 12 standard steam loco designs.
The first to be delivered was Baltimore & Ohio 4500, a USRA light 2-8-2. This engine is currently on display at the B&O Railway Museum in Baltimore, Maryland. The USRA engines came very late: even 4500 served for only a few months before the war ended; many USRA engines were not delivered until after the war.

Up to World War I, 0-6-0 switchers had been sufficient for most switching chores. The 0-8-0 had begun gaining traction, yet 0-6-0s far outnumbered 0-8-0s as late as 1916. During the war, the USRA decided to design both 0-6-0s and 0-8-0s. 0-6-0s were allotted in higher numbers than the 0-8-0, mirroring the trend of the decade prior. Under government control, 175 of the 0-8-0 switchers were produced versus 255 0-6-0s. Increased train weight over the war and interwar period saw construction of 0-6-0s decline rapidly while 0-8-0 production increased. Thanks to the changing trends, the unassuming 0-8-0 switcher became the most copied USRA design, with 1,200 units produced as copies. The design also had significant longevity, with the Norfolk & Western (which did not receive originals) building copies into 1953.

As originally designed, the only significant complaint of the railroads was the lack of rearward vision due to using road engine tenders. These tenders were modified to improve visibility by the receiving railroads. In all other respects, the railroads were generally impressed with the 0-8-0.
