Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 18, p. 233. Works numbers were 13566-13567 in July 1893.
Traffic conditions in Newfoundland apparently enough resembled the ups and downs of San Francisco's Ferries & Cliff House railway to permit Baldwin to reuse the boiler and cylinders--the dimensions were identical. The extra 6"(152 mm) in the gauge permitted a wider firebox, however, and the 8 and 9 benefited from a larger grate.
