FC Santa Fe 2-8-0 Locomotives in Argentina
Class Details by Steve Llanso of Sweat House Media
Class IX (Locobase 3742)
Data from Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([
] Steam Locomotive simulator program (April 2000).
These came to the Santa Fe over a 5-year period (1906-1911). Fernandez, writing on [] (visited November 2004), says these locomotives were well-suited for the lightly built metre-gauge lines that formed an important part of the Santa Fe's service.
Operating on rails with weights of 15-22 kg/metres (30 to 44.5 lb/yard) and 1,000 to 1,200 sleepers per km (1,610-1,932 per mile) on earth ballast, these little Belpaire-firebox, wood-burning engines used an unusual combination of Walschaerts gear and slide valves. Their demand for calories from such a low-energy fuel as quebracho colorado, quebracho blanco and lapacho was only met by embarking an assistant "wood-passer" (pasa lena) who pulled the wood off the high stack carried in the tender. In some cases, he was joined by another known as the arrimador.
The class eventually was superheated and carried on until the 1960s.
