Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 44, p. 268 and 270. Works numbers were 37268 in November 1911 and 40219 in July 1913.
Supplied by American Trading Company and joined by younger sister Marta Abreu a year and a half later, the Villa Clara provided power for this lightly built line that served the Santa Rosa sugar mills in the province for which it was named. Havana lies 166 miles (267 km) to the west while Cienfuegos is 47 miles (75 km) to the south.
A note on Marta Abreu's specs ordered that the sand box be placed just ahead of the cab so that it could spray its sand behind the last set of drivers. To create the room for the sand box, the steam dome needed to be moved forward.
