Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 36, p. 220. Works number was 40735 in October 1913.
Three years after the Muelle de Eten took delivery of one of the smallest standard-gauge Eight-wheelers (Locobase 13752), it bought this smaller saddle tank for dock switching. After 1967, the M de E's government-owned successor Transportes y Embarques del Norte would rename the #9 Tumán.
