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.
Data from DeGolyer, Volume 18, p. 5. See also "Compound Locomotives on the Long Island Railroad", Railroad Gazette, Volume 24, (5 August 1892 and 19 August 1892), pp. 585 and 622. Works numbers were 12700-12703, 12707-12709, 12718-12720 in May 1892.
These were reported to be duplicates of the 45 Chicago & South Side Vauclain compound Forney-type elevated railway described in detail in Locobase 6459. Significantly more cylinder volume was gained by adding 4" (102 mm) to the stroke. A still more substantial driver-diameter increase of 7" (178 mm) allowed for faster running. Reporting that the class was in service, the RG noted that these were"light engines, intended for the lightest kind of suburban traffic" in which they proved "exceedingly good." As an example, RG cited a run in which one of the locomotives hauled "a train of 10 cars [about 210 tons] from Manhattan Beach to Brooklyn, making one stop at East New York." A 1.24% grade was part of the profile. A report two weeks later stated that the class had "given no trouble, except that they do not steam as freely as they might." RG added that it was "though that this defect will be overcome very soon" and that tests comparing the compounds to similar simple-expansion engines revealed a 17 1/2% average fuel economy for the compound. Following the pattern of most Forney-type locomotives, most of this class enjoyed second careers working for small railroads or industrial operations. The list includes Barber Asphalt Paving Co, Sandusky Portland Cement, Carthage & Copenhagen, Newark & Marion, Tioga & Southeastern, Spitcaufsky & Wagner Construction (2), and A O Smith Co.
