Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 242. Works numbers were 29663-29664 in December 1906.
Much had changed in Cuba since 1881, but the specification for a Mogul locomotive for sugar operations obviously had a limited range. So the two (Rayo was #3's name) that arrived in early 1907 had the same dimensions as the engine described in Locobase 11818, although the boiler was pressed a little harder.
