Leopoldina Railway 2-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 189 (Locobase 12351)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 98. Works numbers were 16701-16704 in May 1899 and 17459-17460, 17494-17495 in February 1900.

Two batches of pretty powerful six-coupled locomotives for the metre gauge. Cylinder volume, boiler heating surface area among other measures placed them well up in the set of Moguls delivered for the 3' and metre gauges. One maintenance note in the specs required provision for the link motion to be removed "without having to take down a portion of the foot plate."
