Data from "Some Foreign Compounds", Railroad & Locomotive Engineering, Volume 8, Number 1 (January 1895), p. 29.
All Locobase can find out is that these engines were Wordsell and Von Boories cross-compounds.

Locobase has not been able to match this entry to any South American deliveries during this period. A production list compiled by Dipl Ing Scmeiser shows two sets of three locomotives delivered to the NorOeste in 1892 (works numbers 4478-4480) and 1893 (works numbers 4671-4673) as their 14-19.
The list does show the wheel arrangement and metre-gauge, but does not give cylinder dimensions. The R&LE notes the engines were set up as Worsdell-von Borries cross-compounds.
