Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Vol 16, p. 69.
Works numbers were 11117 in August 1890 and 11517 in January 1891.
Soon after the K & BH was incorporated in Nebraska in May 1889, the Wood River Improvement Company bought these two small Americans, part of a quartet that included 2 others being produced for Vermont's Lebanon Springs Railway (see Locobase 11696). This pair first helped to build then serve a line that would ulitmately stretch 65.74 miles from Kearney Junction, Neb to Callaway. The UP took control of the K & BH in 1894.
Both of these Eight-wheelers were sold by the K & BH in November 1898 to the Wood River Improvement Company as part of the railway's absorption into the Union Pacific. 3 later operated on the Bellingham Bay & British Columbia, a 45-mile road in northern Washington State.
