Data from "Compound Consolidation Locomotives for the Ogdensburg & Lake Champlain", Railroad Gazette, Volume 30, No 6 (11 February 1898), p. 93 See also Dimensions and Classifications of Locomotives of the NYC&HR et al, September 1905, p. 339-340. (Thanks to Wes Barris of steamlocomotive.com for his 28 June 2018 email reporting the missing metric equivalents to cylinder diameter and stroke.) A list of Schenectady production compiled by Robert Lehmuth (and supplied to Locobase in August 2013 by Allen Stanley from his extensive Rail Data Exchange) lists the class's works numbers as 4645-4647 in December 1897.
Firebox heating surface includes 11.5 sq ft (1.07 sq m) of arch tubes. Schenectady heavily promoted the cross-compound version of two-stage expansion during the 1890s, but with little long-lasting success in North America. Outside of articulated compound Mallets, locomotives that started out as compounds were soon converted to simple-expansion. So it was for these three Consolidations. According to Lehmuth's meticulous recounting, the three engines were soon modified as 19" x 28" simple-expansion engines; see Locobase 14561. They later served on the Rutland as their 550-552.Data from Dimensions and Classifications of Locomotives of the NYC&HR et al, September 1905, p. 337.
This diagram book reflected the New York Central's assumption of control over the Rutland in 1905. By that time, the cross-compound setup with which the locomotives had been driven when they were delivered in 1897 (Locobase 3286) had been replaced by the two simple-expansion cylinders shown in the specs. When the New York Central gained operating control of the "Rut" in 1905, it renumbered them first as 2424-2426, then 2402-2404. When local interests regained control of the Rutland in 1913, they renumbered the engines 10-12. As such, the class served the railroad until 1934 with the 11 and 12 being retired in January and the 10 in June of that year.
