Louisville & Nashville operated 22 nearly-exact copies of the USRA Light Mountain in it's L-1 class, numbered 400-421. They were used on heavy passenger trains between Cincinnati and Atlanta and between Louisville and New Orleans. The 14 survivors in 1953 were renumbered into the 470-series to make way for EMD GP7's. 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.
Due to a focus on freight operations in USRA locomotive allocations, relatively few of the USRA passenger engines were built. There were only 47 of these light 4-8-2s built under the USRA, which made it the second most common USRA passenger engine (after the 81 light 4-6-2s). However, the design was modified and copied often following the end of the war. Many roads ordered similar 4-8-2s before and after the war, so this model can easily be a stand in for many 4-8-2 types around North America.
