Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 18 (15 July 1912), pp. 257-258. See also Report by Consul Bennington, "Sao Pedro do Rio Grande do Sul, Consular Report on Commerce, Manufactures, Etc. No. 121 (October 1890), pp. 117-. Works number was 1160 in 1878.
Wiener explained that the 26-mile (43 km] PA&NH between Uargem on the Porto Alegre & Uruguayana and Novo Hamburgo was one of the oldest railways in the republic (having opened in 1874) and the oldest constituent of the RG do Sul. Bought by Rio Grande do Sul State in 1903 and leased to the Compagnie Auxiliaire in 1905, the PA&NH built a connection to Jacuhy in 1910 and became a trunk line connector between Porto Alegre and the interior.
The small Dubs tanks had outsized cabs, a tall stack, small dome, and enormous headlight.
