Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 13 p. 190. Works number was 5627 in May 1881.
Upstate New York's HN&P was chartered to run a 16.5 mile (26.5 km) narrow-gauge line between Herkimer and Poland. For a while, it appeared that the line would stop at Newport because Poland's citizens showed little interest in subscribing to the plan. Pressing ahead anyway, the promoters built the railway up the West Canada Valley, a narrow defile filled with rapids and rock ledges that required costly bridges and "dugways". . The first 8.75 miles (14 km) had opened by 30 September 1881, the other 7.98 miles (12.8 km) to Poland by the end of 1882.
Sentiment to widen the gauge by a third to the standard 4 ft 8 1/2 in (1,435 mm) led to a New York State law approved 16 March 1891 permitting the change. William Webb consolidated the HN&P, its extension to Remsen, and the St Lawrence & Adirondack on 22 June 1892 as the Mohawk & Malone.
At that time, the small Eight-wheeler #1 was soon sold to the Central Vermont and renumbered 9. Apparently a victim of a wreck in the 1890s, the 9 was scrapped by the end of the Century.
The resulting corporation came under the New York Central & Hudson River via lease in May 1893; main line distance between Herkimer and Malone came to 173.1 miles (279 km).
