Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 205. Works numbers were 36717 in July 1911and 60184 in September 1927.
Even though they arrived on the GC sixteen years apart, little changed on the sugar central's railway. Built by the South Porto Rico Sugar Company Trading Corporation, the railway resorted to curve radii of 100 metres (30.5 metres).
