Data from Secretaria da Agricultura, Commercio e Obras Publicas, Relatorio Aprestado ao Dr. Presidente do Estado de Minas Geraes ...Dr Francisco Sa, Vol 1, Primeira Parte, Seccao Primeira-Viacao Ferrea (Ouro Preto-Imprensa Official do Estado de Minas Geraes, 1895), pp. 48-50. See also DeGolyer, Volume 17, p. 70. Works numbers were 14139-14148 in October 1894.
The Baldwin specifications and the extensive details given in the Brazilian report agree in most respects except for the tube heating surface area. Locobase suspects the difference reflected a Leopoldina calculation using the inside diameter for the tubes.
The ten engines were named Coelho Bastos, Andre Cordeiro , Martins Esteves , Parreiras Harta, Jacintho Bittencourt, Carlos de Niemeyer, Fernando Lobo, Porciuncula , Miguel de Corvalho, and Antonio Lage.
The class was rated with a trailing load on the level of 1,413 tons.
Data from "Consolidation Locomotive, Leopoldina Railway," Locomotive Magazine, Volume 20 (15 September 1914), p. 235. (Teemu Koivumaki for his 20 March 2021 email reporting the works numbers for this batch.) Works numbers were 3581-3582 in 1914.
This Consoldation design was based on the earlier class delivered in 1907 and shown in Locobase 20284. The new batch gave a nod to modern practice by including a superheater and outside constant-lead radial valve gear operating piston valves. It was one of the smallest 2-8-0s operating on the Brazilian metre gauge even with the superheater area added in.
Data from Charles S Lake, "New Locomotives for the Leopoldina Railway," Model Engineer and Electrician, Volume 17 (31 October 1907), p. 421. (Thanks to Teemu Koivumaki for his 20 March 2021 email reporting the works numbers for this batch.) Works numbers were 3214-3219 (?).
A typical cabbage-stack Consolidation of quite modest proportions even for the metre gauge. Its Belpaire firebox was connected to a slightly smaller diameter boiler with a tapered brass collar.
A 1914 update with superheater appears in Locobase 20285.
Data from Lionel Wiener, Les chemins de fer du Breñsil (Paris: H. Dunod et E Pinat, Editeurs, 1912), p. 115. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Tentative works numbers were 5001-5009 in 1914.
Using both Temmu Koivumaki's spreadsheet and Jens Merten's Kitson production list, the closest Locobase comes to locating the Consolidations in question shows a build date of 1914 and 18" (457 mm) cylinder diameter. But a 1914 date conflicts with Wiener's publication date pf 1912.
