Data from "Compound Ten-Wheel Locomotives for the Buenos Ayres Western Railway," The Railroad Gazette, Vol XLIII, No 10 (6 September 1907), pp. 269-270. See also DeGolyer, Volume 29, p. 220. Works numbers were 30765 and 30845 in May 1907, 31154-31156 in June.
This was the American contribution to the British version of the Von Borries cross-compound design that began with the 1904 deliveries recorded in Locobase 2720. Differences in these Baldwins from those engines were slight - the basic layout of clean boiler, inside Stephenson link motion, Belpaire firebox, and short cab remained the same.
At least one -- 696 -- was rebuilt in 1942 and renumbered 1064.
