Fairfield Traction 0-4-0 "Switcher" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 12269)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p. 170. See also John H White, The American Railroad Passenger Car, Volume 2 (Baltimore, MD: Johns Hopkins University Press, 1978), pp. 585-587 and "Steam Motor Cars for Minor Railway Lines," Railway World [London], Volume 7 (5 May 1898), pp. 138-140. Works number was 15887 in April 1898.

See Locobase 12237 to see an outline of Baldwin's steam coach design. White archly notes that the company managed to sign two Midwestern companies to contracts for a larger design with a much larger coach before the Woodsdale's "disgrace" became apparent.

Detroit & Lima Northern was one buyer, but suffered cold feet even before the vehicle was ready. Thus the car went to Fairfield Traction, which operated it briefly before removing the engine and dedicating that to a small switcher while converting the body into a combine coach.
