Tramway Rural Fluminense 0-4-2 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Nilo Pecanha (Locobase 13493)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volumes 32. p. 308. Works number was 32998 in October 1908 and 40031 in June 1913.

This locomotive apparently was named for the then-President of Brazil. It was bought by the locomotive-brokerage firm Knowles & Foster. The second engine was named Joao Medina and given #5.

Across the bay from Rio de Janeiro, Niteroi offered a quieter alternative and grew steadily, counting 50,000 persons in 1910. The two engines served the TRF's line, which extended from Neves (end of the Niterói horsecar line) to AlcGntara, pulling trams until 1917 when the electrified TRF entered service on 15 February.
