Data from "Steam Motors for Street Service", Railway and Locomotive Engineering,, Volume 23, No. 2 (February 1910), p. 66. For the ECU, see Allen Morrison, "The Tramways of GUAYAQUIL Ecuador", presented on the Web at [] . See also Martin Coombs, Part 6: Ecuadorian steam locomotive list from his Railways of the Far South series, v.1.24 (March 2026) on the web at [], last accessed 7 March 2026. Works numbers were 4430-4435 in November 1909. (Six slightly earlier dummies credited with 5" x 8" cylinders appear as works numbers 4270-4272 and 4318-4320.
RLE acknowledged that by this time in the development of street railways, "Electricity has pretty nearly monopolized the street railway field." The tramway for which these were produced converted from horsecars by adopting the "steam dummy" produced by both Porter (12) and Orenstein & Koppel (4). Porter's was a tiny motor with a vertical boiler.
The result delivered only partial success, according to Morrison: "The public was happy to see fewer animals on the streets, but did not like hot, noisy, smoky locomotives running near their homes. Newspapers and magazines reported numerous accidents and complaints. The caption on this cartoon announces: "Another noisy new monster has arrived to puff through our streets" [Patria, Guayaquil, 3/1909]"
Like most other steam-powered trams, the class soon phased out in favor of the electric trams that were not long in being adopted.
