Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 19 (13 January 1913), pp. 16-17. Works numbers were 4021, 4020, 4019 in 1903.
The Taquara was a 28-mile (45.1 km) extension of the PA&NH that opened in 1903. This trio of German-built tank engines (the first from that country to run on the Rio Grande system) were all the motive power the Taquara would buy. In 1905 all of the PA&NH was bought by the state of the Rio Grande do Sul and integrated into the Compagnie Auxiliaire's system. The locomotives arrived with spark-arresting diamond stacks, outside Stephenson link motion, prominent "cow catcher" pilots, long side tanks, and large cabs. The LM reported that the class went through two significant changes. First, they were too heavy and too wide for other parts of the system, so they were converted to 0-6-0 tender locomotives trailing four-wheel tenders. Apparently ride quality and tracking were still an issue because the RGdeS in1910 fitted a pony truck ahead of the drivers, creating a 2-6-0 with an engine wheelbase measuring 16 ft 8 3/16 in (5.08 m). That change and the careful distribution of four tons of extra weight on the frame. Result: "The locomotive rides easily and steams well after this recent transformation."
