Long Island 0-4-4 "Forney" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 105 (Locobase 11753)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 9, p. 103. See also [], last accessed 7 November 2010 and F J Camulla, "The New York Elevated Railroads," Industries and Iron, Volume 1 (24 December 1886), p. 662-663. Baldwin works numbers were 4649, 4652-4653, 4655-4657 in May 1879.

These Forneys had worked the elevated section of the LIRR from Brooklyn's Flatbush terminal and eventually served the line as far out as Rockaway.

(Chapter 19 of James Blaine Walker's Fifty Years of Rapid Transit (New York: Press of The Law Printing Company, 1918) -- [], last accessed 7 November 2010 -- has the juicy details of political maneuverings in 1879-1884 that included the jailing of all of the Brooklyn aldermen after they defied a mayoral veto of their award of the contract to the Kings County Elevated Railroad Company.)

After 25 years of service, the lines were electrified and the Forneys were sold in 1903-1904 to locomotive rebuilder/reseller Birmingham Rail & Locomotive. BR&L found new homes for the entire class in lumbering, a kind of railroading that suited the low axle loadings and starting-traction power of the 0-4-4T arrangement.
