74 was the last new locomotive built for the Copper River & Northwestern. Constructed by Alco’s Brooks Works in August 1917. The locomotive lasted until the end of operations in 1938 and was sold to the Midland Terminal as their #63 in 1940. The Midland eventually sold the engine in December 1948 to the Ferrocarril Noroeste de México (Mexico Northwestern Railway) as their #201. From there, it may have become Ferrocarril Chihuahua al Pacífico #201 before presumably being scrapped.
