See also Eduardo Jose de Jesus Coelho, Brazilian articulated steam locomotives (Memoria do Trem, 2003), p 38. Works numbers were 2091 in 1927 and 2108 in 1928. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.). His locomotives list suggests 2109 might also have been part of the order.)
As with other Saint Leonard garratts, these were licensed from Beyer-Garratt. Another in a series of industrial Garratts from this firm and the only industrial Garratts to operate in South America. These pulled cane cars from the plantations in Lorena, Piracicaba, and Porto Feliz among others.
The pair had small boiler, cab, bunker, water tank, but a large balloon spark-arresting stack By this time, most other Garratts used at least one leading (and, consequently, one trailing) carrying truck.
Coelho wrote that the two engines enjoyed long careers before being retired in 1972.
