Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 11, p. 155. Works numbers were 6404-6405 in October 1882.
This railway, located not far from Rio de Janeiro, was the successor to Brazil's first railway, the E de Ferro Maua. The line was extended from Piabeta to Petropolis Serra (a precipitous ridge lying about 10 miles from the port of Maua) and Areal between 1883 and 1886. The entire line later joined with others to form the Leopoldina.
