Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 18 (15 July 1912), p. 145. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers were 2226-2228 in 1879.
These were the first locomotives bought for the PAeU, which was then owned by the Brazilian government. In 1898, Brazil leased the lines to the Compagnie Auxiliaire des Chemin de Fer au Bresil for a period that was extended to 1968 in 1912.
