Data from DeGolyer, Vol 79, pp. 241+. Works numbers were 60803-60804 in May 1929.
The EFI was located in the state of Espirito Santo and was named for the river that flows across the entire state and forms its southern border with Rio De Janeiro. This bi-fuel Mogul (coal or wood) had grates and tender that could be made suitable for either one (3 1/2 cords of wood).
