Costa do Mar 2-4-2 Locomotives in Brazil

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 20099)

Data from Lionel Wiener, "Locomotives of the Rio Grande do Sul", Locomotive Magazine, Volume 18 (15 November 1912), p. 235. See also "Southern Brazilian Rio Grande do Sul Railway", Railway News, Volume 73 (26 May 1900), pp. 808-811. (Thanks to Teemu Koivumaki for his 14 June 2020 email putting Locobase on the trail of the three locomotives by providing their Porter works numbers.) Works numbers were 1034 in May 1889, 1191 in July 1890, 1231 in December.

Wiener claimed that this trio of saddle tanks was produced by the "Porter Locomotive Works, of Delaware". Porter had no facilities in Delaware and Porter rosters show no such locomotives being produced anywhere for Brazil. Teemu Koivumaki's email led Locobase to Robert Lehmuth's Porter builder's list (supplied by Allen Stanley from his extensive Rail Data Exchange collection).

Ultimately, the New York City firm Coombs, Crosby & Eddy ordered all three locomotives; CCE was well-known as a leading broker in South American business. According to Koivumaki, works number 1034 originally served the Companhia de Bonds Suburbanos da Mangueira as their #1 Andorinho. This company quickly rebranded itself as the EF do Rio Grande a Costal do Mar. Lehmuth's list reflects a more complicated path for the later pair as they were bought by S.H.Payne for Coombs Crosby & Eddy. Koivumaki suspected that they too wound up on the Costa do Mar and Wiener's grouping the three together support that idea.

"These engines, " Wiener wrote," were built for passenger service and carried sufficient water in the salddle tanks to make the 10 mile [16 km] run."

G Von Chauvin, chairman of the RG do Sul, used this line to outline the principles of capitalism during the general meeting remarks in 1900. "The small line which you have seen figuring in our report for the last ten or twelve years--Costa do Mar--will most likely pass into possession of this company. The owners of the Costa do Mar Railway ...are tired of working the line. We have received a nice commission out of working that business, and we, of course, by controlling that traffic to a little seaside resort on the coast, have been able to direct that traffic in the best way for our own purposes on to our own system. But the owners of that company have not made any hay over it. The company are tired of it and want to give it up."

And, of course, they soon did.
