Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 34, p.340. Works numbers were 34077 in November 1909 and 36095 in February 1911.
The weight problem this Ten-wheeler posed for the Entre Rios in their first locomotives clearly did not go away. Although 5 were ordered in 1908 (Locobase 12907), a sixth was diverted from the ER to the FCCBA and another of identical design a year or so later. Compared to the 1908 trio delivered to the FCCBA, these locomotives had 8 fewer tubes, but was otherwise quite similar.
Note that the specs included extracts from the Law and General Regulations of the National Railroads of Argentina that governed the types and data concerning locomotives and tenders.

See also Stephen H M Killik, Manual of Argentine Railways for 1908 (London: Effingham Wilson, 1908), pp. 31- 33. Works numbers were 32580-32582 in January 1908.
The CBA was built on light rails at the turn of the 20th Century. The 1908 version still ran on 47-lb/yard (23.5-kg/metre) rail. The main line ran from Buenos Aires to Salto, 108 miles to the west and an extension of 30 miles to Rojas was under construction. The Zarate branch ran from a point 35 miles west of the capital to the Parana River.
