Data from Lionel Wiener, writing in Cassier's Magazine - an engineering monthly (Vol XXXVIII, #2, June 1910), p 110; and DeGolyer, Volume 32, p.265. Works number was 32896 in August 1908.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 48. Works numbers were 13841 in November 1893 and 14475-14479 in October 1895.
Vauclain compounds were sold for all purposes; all had piston valves (these were 8" in diameter) and higher pressure boilers.
The proper name for the railway on which this Ten-wheeler operated was the Prolongamento do Bahia & San Francisco. After testing the 28, the Bahia bought a batch of 5 more. These had names: Antonio Olyntho, Fernandes Pinheiro, Rocha Dias, Miguel Burnier, Pires Ferreira.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 20, p. 131. Works numbers were 14815-14819 in April 1896.
After the initial trial with the Vauclain-compound Ten-wheeler delivered in 1893 and described in Locobase 12090, the Bahia chose to go with the simple-expansion system and ordered five identical locomotives with 16" x 20" cylinders.
