Data from DeGolyer, Vol 66, pp. 307+. See also Joao Emilio Gerodetti and Carlos Cornejo, Railways of Brazil in Postcards and Souvenir Albums (Solaris Editorial, 2005) , p. 24. Works numbers was 52627 in December 1919.
Work on the EF Rio D'Ouro was begun in 1876 to build a line that would carry construction equipment and materials to support the building of reservoirs and the associated aqueducts that supplied Rio de Janeiro. After that phase had passed, the railway came under government ownership in 1878 and began passenger service on 15 January 1883.
By 1925, the D'Ouro comprised 145 route km (90 miles) of track. And this wood-burning Mogul worked freight trains on the line.
