Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol ume 17, p. 161 Works numbers were 11559, 11568 in January 1891; 12937, 12949 in September; 13619 in August 1893; 14304-14305 in April 1895
The Parana, by this time owned by the Compagnie General de Chemins de Fer Breslien, operated a 110-mile(177-km) line from Paranagua to Curutiba over an often precipitous and steeply inclined profile. These Moguls were relatively large examples of their wheel arrangement at the time they were built and they needed every bit of power.
