Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 205. (Thanks to Chris Hohl for his 23 October 2019 email reporting the correct boiler pressure.) Works number was 18627 in January 1901.
Locobase 12269 describes the failure of the Baldwin steam railcar design and its rapid conversion to a switcher. The need for traction on this street railway remained, however, and the company bought this small saddle-tank engine. The earlier unit's engine truck contributed many of the running gear's parts: "cylinders, wheels, axles, [axle] boxes, connecting rods, valve motion (except reversing shaft and lever), crossheads, guides, and truck. Also frames which are to be welded out."
8" (203 mm) piston valves served the cylinders. But the earlier unit's self-firing feature was to be omitted and fuel capacity needed to be increased to confer a 25-mile (40 km) range.
Surviving Fairfield Traction's reorganization as the Lancaster Traction & Power company, the 1 was sold to the locomotive rebuilder/reseller Southern Iron & Equipment in 1907.
