Empresa Industrial do Melhoramentos no Brazil 4-4-0 Locomotives in Brazil

Class unknown (Locobase 11180)

Data from Exhibit of Locomotives by the Baldwin Locomotive Works (Philadelphia: J B Lippincott, 1893), pp. 54-57; and DeGolyer, Volume 18, p. 178. (Thanks to Chris Hohl for his 13 January 2020 email and extensive spreadsheet covering all of the locomotives at the Exposition.) Works number was 13351 in April 1893.

At the time of the 1893 Columbian Exposition, Baldwin was hitting its stride in the development and promotion of Vauclain's four-cylinder compound design. Locomotives of nearly every kind would eventually appear with the setup. But few if any would use such small (7"/179 mm) piston valves to supply steam to each pair of 1 HP and 1 LP cylinders.

Reflections on experience with the Leopoldina's Leopoldo Leite (Locobase 20705), Baldwin's specification contained the railway's request to increase the weight to 40,000 lb, if possible and to lengthen both the wheelbase and the tubes by one foot (305 mm). As noted in their entry (Locobase 20704), the changes were laid out in the spec used to build the Oeste de Mina pair two months earlier.

After the exposition, the locomotive was delivered to the MdeB, which later merged with the EF Central do Brasil. The engine took road number 25.
