Prototype: The firm of Baldwin built two modern Mallet locomotives in the 1920s for the Uintah Railway in Utah and Colorado. These locomotives are still today the largest narrow gauge locomotives ever to run in the USA. When the Uintah Railway was shut down, both of these powerful Mallets went to the Sumpter Valley Railway, which transported agricultural and forestry products in the eastern part of Oregon. The locomotives were equipped with tenders and soon provided a considerable part of the transport service in this scenically very attractive area. The Sumpter Valley was finally shut down also. The two Mallets were sold to the International Railway of Central America in Guatemala, where they were in operation well into the 1960s.
