Class Details by Steve Llanso of Sweat House Media

Class Class 65 (Locobase 20065)

Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 18 (15 July 1912), p. 145.

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.
