Federaux de l'est Bresilien 4-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 20 (Locobase 15104)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 66, p.193 and Vol 72, pp. 117+. Works numbers were 55119-55123 in November 1921, 55398, 55411(26), 55421 (25) in May 1922, 55528-55529 in July. Another three--57929-57931--in July 1924.

These small wood-burning Ten-wheelers had outside constant-lead radial valve gear operating 8" (203 mm) piston valves. Their specs indicated typical narrow-gauge limitations of 2% grades and curve radii of 100 metres (328 feet). Also, the springs were to be made "extra strong, account of extreme roughness of road." Tenders held 3.6 cords of wood in a bunker measuring 13 cubic metres (459 cu feet) in volume. The fuel supply dictated the use of a Rushton Improved cabbage stack to arrest sparks.

The stack needed tweaking after delivery "to improve steaming," according to a "Hereafter" note.The barrel was extended ten inches (254 mm) to 17" (432 mm) high, the stack cone diameter increased by an inch to 26" (660 mm) and the distance from the spark netting to the bottom of the cone decreased by an inch to 3" (76 mm).

The three later engines were built to the same specs for the nationalized Fl'EB (now called Este Brasilero) but somehow weighed 3,000 lb (1,361 kg) more each. Tender capacity was unchanged, but loaded weight increased by 3,500 lb (1,588 kg).


Class 357 (Locobase 13972)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p. 131. Works numbers were 39247-39251 and 39315-39321 in February 1913.

The French-owned Bresilien sought out superheat ahead of most of its contemporaries and bought this large batch of dry-steam Ten-wheelers at the same time they bought their Atlantic quintet (Locobaes 13971) and the Consolidations described in Locobase 13973. Like the Atlantics, these engines had 8" piston valves (with "vacuum valves"), but their deep fireboxes sat inside the frames and the drivers were smaller.

See Locobase 13973 for Baldwin notes from 1915 that described problems with all of the engines ordered on this date. One general observation was that the locomotives were not quite sturdy enough for "very rough road service."


Class 58 (Locobase 13773)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 36, p.278. Works numbers were 34401-34402 in March 1911.

On the very same day that Bresilien ordered Moguls (Locobase 13772) and Consolidations (Locobase 13774) from Baldwin, it also purchased 2 wood-burning Ten-wheelers. Although they had the same power dimensions, the latter were the passenger engines, rolling on taller drivers and thus exerting less tractive effort. The boiler and firebox were essentially duplicates of those of the Moguls, but longer by 18 inches.
