Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 14. Works number was 35780 in December 1910.
Although a little lighter than the 1904 Woodward Iron Mike shown in Locobase 12693, this was essentially the same design. The Y & OR RR was an electric interurban line that interchanged freight with several railroads. For that service, they needed a small freight engine and this one operated for about seven years, at which point two Baldwin-Westinghouse steeple-cab electrics replaced it.
In 1917, the 1 was sold to the Hetch Hetchy Railroad, which served the effort to build the San Francisco Dam then under construction. (See Robert Righter, The battle over Hetch Hetchy: America's most controversial dam (New York: Oxford University Press, 2005)). In 1927, the 1 went to the California & Oregon Coast as their #301. After decades of service, the 301 was scrapped in 1950.
