Data from "Brazil Great Southern Ry", The Locomotive, Volume 16 (15 August 1910), p. 176. See also Frederic M Halsey, Investments in Latin America and the British West Indies, Special Agents Series - No 169, United States Department of Commerce (Washington, DC: Government Printing Office,1918) p. 158. Works numbers were 4715-4717 in 1911.
It's hard to figure that a 20-year-old railway would be buying locomotives 1, 2, and 3 in 1910, but this trio of very small Ten-wheelers was headed for the Extensions, which opened in 1913.
Halsey's 1918 report noted that the railway hadn't paid a dividend on its shares for the past 26 years and that 154 per cent of the back dividends was due on the 7 per cent cumulative preference shares. That is, this railroad operated in a constant state of penury. It connected the Uruguayan border town of Quarahim with Itaqui (110 miles/177 km away) and an extension to Sao Borja that covered another 77 miles (124 km).
