Texas & Pacific 2-6-0 "Mogul" Type Locomotives

Class C-1 (Locobase 8491)

Data from T&P 1 - 1922 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

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.
