Data from "Double-End, Narrow-Gauge, Tank Locomotive for the Matanzas Railroad", Railroad Gazette, Volume XI [11] (28 March 1879), p. 167. Works number was 2504 in November 1878.
Relatively large for its day and gauge, this wood burner continued a long-standing partnership between the Paterson,NJ builder and the Cuban north shore sugar producer. It joined an earlier Rogers double-ender (works number 2395 in February 1875), which rolled on 30" (762 mm) drivers as a 2-4-4T with 11"(279 mm) x 16" (406 mm) cylinders.
This may have been the first tank engine to have a six-wheel bogie under the tank. A large cab with extended roof dwarfed the slender boiler, although the other end featured an enormous spark-arresting cabbage stack over the smokebox. The latter rested on an extension of a frame that began just behind the last set of drivers. Roger's William Hudson had developed the definitive leading truck for a Mogul arrangement (see Locobase 2558) and that setup served the 32 as well.
