Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 106. Works numbers were 10057, 10059-10060, 10063 in June 1889.
Although sold and lettered for the E de F Dom Segundo II, these were delivered to its successor, the Central do Brazil. A note in the specifications for these narrow-gauge Eight-wheelers describes Baldwin's guarantee that these engines would handle 185-ton trains up a 1% grade "...except resistance curves."
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 73 . Works numbers were 12112-12114 in August 1891 and 12727-12728 in June 1892.
This was a classic Vauclain compound Eight-wheeler whose 9" piston valves fed the grouped HP and LP cylinders on each side.
Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 18, 153. Works numbers were 13179-13181, 13187-13190, 13193 in January 1893; 13195-13198, 13201, 13206-13210, 13225, 13231 in February.
This class of 20 Eight-wheelers was fitted with large Belpaire fireboxes. They followed a large order of Vauclain compound engines with 11 1/2" HP and 19" LP cylinders.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 31, p. 163. Works numbers were 32614-32619 in January 1908 and 33142-33150 in January 1909.
Data from Lionel Wiener, writing in Cassier's Magazine - an engineering monthly Volume XXXVIII [38], No 5, (October 1910), p 470. See also DeGolyer, Volume 21, p. 91. Works numbers were 15623-15624, 15628-15633 in December 1897.
These Eight-wheelers were intended for a broad gauge line that had 1% ruling grades and gentle curves of 590 ft radii. Designed to burn high-calorie "Cardiff coal", the design had grates made up of 9 sq ft (0.84 sq m) of "water [fire brick] tubes" with intermediate bars placed close together," according to the Baldwin specification.
Belpaire's reverse gear had a set screw ahead of the lever.
Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899); Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Works numbers were 2514-2518.
Featuring a rather blocky "Improved Belpaire" boiler, this quintet showed an oversized cab, flat-topped firebox, large headlight, and inversely tapered stack.
