Data from "Goods Tank Engine, Buenos Ayres and Campand [sic] Railway", The Engineer, Volume 42 (29 December 1876), p. 444. Works numbers were 130-131 in December 1874 and 132 in January 1875.
The Engineer reported that these goods engines had proven to give "very satisfactory results in point of economy in fuel and repairs." Moreover, Engineer claimed the design was "very evenly balanced, and, as a consequence ...extremely steady in running, and they get away quickly with their loads."
