Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 71, pp. 165+.Works number was 57613 in January 1924.
Locobase 14335 discusses the history of the Slow, Jerky & Expensive. This Prairie came ten years after the earlier Baldwin and featured some superheating and shorter drivers. Piston valves measured 9 1/2" (241 mm) in diameter. When the SJ&E closed in 1933, the 205 was sold in November to the Santa Maria Valley to haul oil and asphalt between Roadamite to Guadalupe, Calif. When the 205 was retired in 1950, it was donated in May to the city of Santa Maria, where it stood on display for over 30 years. George Lavacat bought the engine in 1983 and stored it on the Willamina & Grande Ronde Railroad.
