Central Uruguay 4-4-0 Locomotives in Uruguay

Class Details by Steve Llanso of Sweat House Media

Class C (Locobase 20435)

Data from "Locomotives from Uruguay", National Car and Locomotive Builder, Volume , (October 1892), p. 150. See also Juan Jose Castro, Treatise on the South American Railways and the Great International Lines, Published under the Auspices of the Ministry of Foment [sic] of the Oriental Republic of Uruguay and sent to the World's Exhibition at Chicago (Montevideo: La Nacioon Steam Printing Office, 1893), pp. 118-119. Works numbers were 3295-3300.

Although the Treatise refers to the Robert Stephenson built compound Eight-wheelers, its table shows all twelve locomotives (6 Stephenson, 6 Beyer, Peacock) as a class. Castro noted that the C class hauled 250 tons gross weight up a 1.6% rising grade or could, with a light train, "easily travel at the maximum permitted of 72 kilometers (45 miles) per hour.
