Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 32, p. 55. See also "Railway Systems - Brazil", Monthly Consular and Trade Reports, No. 322 (July 1907) (Washington, DC: Government Printing Office, 1907), p. 175. Works numbers were 33201 in February 1909.
The tender behind this little 6-wheeler is surprisingly big and held a considerable amount of water for the size of the engine. It was required to scale 2 1/4% grades.
The Goyaz began from the terminus of the Oeste de Minas at Formiga and was intended to extend a total of 436 miles (702 km) to Goyaz. According to the 1907 Trade Report, the Brazilian government had authorized support for settlers "...of one nationality and as far as possible from the same portion of the same country to form communities in Brazil. The inducements offered are very liberal."
Construction of the Goyaz saw a revision by the Minister of Public Works of Brazil in which the railway would run across the State of Goyaz through the capital to San Leopoldina, on the Araguaya River. "The road is to have two branch lines, one going to Araxa and Uberaba and the other through the Paracatu district to the Tocatins River, in the north of the State."
Details of the "'nucleus' colonies" included the establishment "...at certain convenient points yet to be selected, the colonists being given land as their own property, as well as further assistance until crops can be harvested. The road to Arcos is expected to be in operation by the end of the year. The Uberaba branch will be pushed as rapidly as possible to open up the country dependent upon it."
