Boston & Albany received ten light 2-10-2's from the USRA, class Z-1, #1100-1109. After the purchase of the 2-8-4's, these engines were seen as too slow to keep up and they were sold, first to CCC&StL in 1926, then NYC proper in 1927, then to Canadian National. 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.
94 of the light USRA 2-10-2s were allocated and delivered. Only 4 copies were built after USRA control ended. That makes the 2-10-2 the 2nd least copied USRA design (after the light Mallet with 0 copies). There were many reported teething problems and small nitpicks initially, but the light 2-10-2s did provide good service until the end of steam on the few roads that got them.
