Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 139.

Baldwin's 0-4-2T (retangular side tank or saddle) was a common sight on many plantations and in other low-speed, light-haul settings. This wood-burner was a little unusual in having neither a name nor a number, but otherwise it followed the pattern.
When the railway was projected in 1906, the plans called for 246 miles (396 km) of line. By 1912, the Caxias-Codo segment (52 miles/83.7 km) and the Rosario-Itapicuru portion (34 miles/54.7 km) were open. Surveys for branch line from Coroata on the SL a C to the Tocantina River had also begun. One of the biggest projects--the Benedito Leite bridge connecting Sao Luiz on the island of Maranhao with the mainland--was reserved for the very end of the project and didn't open until 1928.
