Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 39, p 241. Works numbers were 37515-37518 in February 1912.
The RSM was a government-subsidized railway that resulted from the merger of two smaller railways in the state of Minas Gerais -- Estrada de Ferro Minas e Rio and Viatpo FTrrea Sapucaf -- in 1910. The quartet of wood-burning Consolidations responded to a specfication that described a maximum grade of 3% (158.4 ft/mile, to be exact) and curves as tight as 80 metres (262 ft) in radius.
