Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University,Volume 78, pp. 262+. Works numbers were 58549-58551 in July 1925.
Baldwin sold a lot of this small superheated Mikado design, most to Brazil. Three of them were built for stock (along with a single engine for a Brazilian importer) and redirected to the FCCC. Changes to the design were covered under Extra Order 2005 (1927). Most of the alterations were minor. A couple involved more work: the smoke box spark arrestor was removed and netting, deflecting plates, and a cleaning pipe were installed. Also, the standard back truck axles were replaced with reinforced axles under Extra Order 1115 (1927).
Each engine was shipped fully erected. Lifting slings necessary for unloading the locomotives and tenders at Rosario were supplied from a Brazilian shipment.
Data provided by Carlos Alberto Fernandez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000). See also "New Meter Gage [sic] Locomotives for South America", Railway Age, Volume 68, No 20 (12 November 1920), pp. 839-841. Works numbers were 61521-61526 in February 1920, 62638-62652 in November-December.
Quite a bit bigger than the earlier Cordoba freight engines and among the most powerful Mikados to run on the metre gauge. RA reported that many of the dimensions conformed to British practice. In addition to displaying pressures in kg/cm2 and temperature according to both Fahrenheit and Celsius scales, all of the bolts used a Whitworth pitch of 11 threads per inch.
They were rated at 1,000 metric tons (1,100 short tons) up a 1 1/4% grade.
