Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000). Built 1886-1889.
Fernandez, on [] (visited August 2002), says that unlike most Argentine 2-6-0s, this class was not relegated to branch-line work and retired as larger engines came into service. Instead they moved easily from main-line sugar trains to lightly built branches where the heavier locomotives couldn't go. As a result, many in this class operated for almost 80 years each.
