Buenos Ayres & Campana 4-4-0 Locomotives in Argentina

Class Details by Steve Llanso of Sweat House Media

Class II (Locobase 21135)

Data from "Goods Tank Engine, Buenos Ayres and Campand [sic] Railway", The Engineer, Volume 42 (24 November 1876), p. 358. Works numbers wre 320-324 in 1876.

The BA&C connected Argentina's capital city to the deep-water port of Campana, 50 miles (80 km) away on the Parana River.

According to the Engineer's report, superintendent Cleminson's design had bogie bar frames "so universally used in the United States," but it wasn't built up with layers of flat iron. Rather, "the several parts are strong forgings, marchined and fitted together with the greatest precision." On the other hand, the main frame was of the typical British "plate kind ....of such a form as to afford immense vertical stiffness."

Performance was reported to have included "very moderate consumption of fuel and with very little expenditure on repairs."
