Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 19 (13 January 1913), pp. 16-17. Works number was 440.
This was the only locomotive ordered by the Caxias (an extension of the Porto Alegre and Nuovo Hamburgo) before it was absorbed by the Compagnie Auxiliare in 1909. Wiener reported that this extension ran for 100 miles (160 km) through "a hilly and most picturesque tract of country."
The report explained that the carrying axle under the cab used axle boxes whose sockets received the spherical end of a vertical rod connected on the other end to a leaf spring. The axle boxes themselves had horizontal rods leading forward to pins that pivoted. (The goal, obviously, was to achieve the most flexibility possible.)
