Saddle tankers with inside cylinders built by various British manufacturers over a long period (1883-1910).
Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000). See also "Central Argentine Railway - FCCA 0-6-0T steam locomotive Nr. 949 (Beyer Peacock Locomotive Works, Manchester-Gorton 6013-32 / 1920)", "Historical Railway Images' on Flickr at [], last accessed 28 April 2024. Works numbers were 5704-5718 in 1913, 6013-6127 in 1920-1921, and 6028-6032 in 1921.
The builder's photo shown in HRI depicted a typical British six-coupled-coupled tank except for the outside constant-lead radial valve gear.
Raúl Alejandro Rodríguez commented "I saw this locomotives in this last services.- When I was a boy (that is in the 50's) this engines were working in the yards of Retiro Station."
