Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p. 267. Works numbers were 32905-32910 in August 1908.
This sextet of Ten-wheelers was delivered to the FCCNA to help to build the railway. It had a Belpaire firebox made of copper that would burn either wood or coal.
Data from Record of Recent Construction #54 (Baldwin Locomotive Works, 1905), p. 24-25. See also DeGolyer, Volume 28, p. 2. Works numbers were 25029-25030 in January 1905 and 25045-25046, 25070, 25076-25079, 2509-25092, 25095 in February.
Among the operational conditions were curves with a minimum radius of 100 m (328 ft). Oil cups had to be of sufficient capacity to allow 200 km (124 mi) without refilling and the driver and front truck tires had to be guaranteed to run 350,000 km (217,350 miles).
The design's deep, narrow Belpaire firebox provided a good percentage of evaporative heating surface area. The cylinders received their steam through piston valves.
Many precise notes in the Baldwin specs include the requirement that the boiler be "strengthened with longitude or gusset stays." Another advises that the dry pipe (which conveyed the steam from the regulator to the smokebox) be made of "soft seamless copper of sufficient thickness to prevent collapse from external pressure that it has to support."
Data from "Locomotive Building", Railway Age Gazette, Volume XLV, No 11 (14 August 1908), p. 732; and "Locomotives for the Central Northern Railway of the Argentine [sic]", Railway and Locomotive Engineering, Volume 22, No. 3 (March 1909), p. 129. Works numbers were 45619-45628 in October 1908.
The FCNA ordered 30 locomotives from Alco in 1908. Twenty were the relatively large Pacifics described in Locobase 12883. Ten were these freight Ten-wheelers, which were smaller and less powerful. Their narrow Belpaire fireboxes were made of copper.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 28, p. 249. Works number was 27361 in January 1906.
The Luis Stremiz construction company bought this Ten-wheeler and soon sold it to the the Central Norte.

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 26, p. 293. Works numbers were 24034, 24048-24049, 24078 in April 1904.
Priotti's data showed a smaller boiler, but Locobase chose the Baldwin specs because of their completeness while acknowledging the possibility that the engine lost some boiler tubes before delivery or in a later update.
The specs reported a requirement that the engine pull 300 long tons of "cars & lading" up a 1 1/2% grade (78 feet/mile) at a speed of no less than 15 mph (24 km/h) and negotiate curves as tight as 100 metres (328 ft) in radius.
