Data from T&P 1 - 1922 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 3224-3228 in March 1883, 3233-3237 in April,
By the time the 1922 diagram book was published, this class of Moguls had been relegated to switching duty. When originally delivered, however, they undoubtedly served as freight and mixed-traffic locomotives all over the system.
