Sao Luiz a Caxias 0-4-2 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 14204)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 49, p. 139. See also Carlos Cornejo e Jopo Emilio Gerodetti, Railways of Brazil in Postcards and Souvenir Albums (Solaris Editorial, 2005), p. 248. Works number was 40321 in August 1913.

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.
