Baltimore & Ohio S-class 2-10-2 6001

Baltimore & Ohio operated 31 extremely large (by anyone's standards) 2-10-2's in class S starting in 1914. They were improved slightly and re-ordered in 1923-26 as their famous class S-1 and S-1a, some of the heaviest, most powerful, and perhaps the fastest and best balanced 2-10-2's ever built. During WWII, B&O considered rebuilding them into 2-10-4's (and some Mikes into 2-8-4's) along with the T-3 rebuild program, but the new-fangled FT's and E-units changed that. The S's were used mainly as pushers while the S-1's handled mainline traffic of all sorts, including hot merchandise trains. The boilers from two S-class were used in building the first 4-8-2's that weighed more than 400,000 pounds while the running gear was used in building the two largest 0-10-0's ever built. The USRA Light 2-10-2, let alone the Heavy version, can't hold a candle to the B&O engines, but it will stand in until a more suitable model is available. 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.
