Data from DeGolyer, Volume 66, pp. 134+. Works numbers were 54282-54283 in January 1921.
This engine was essentially identical to the Mallet tank that would be built for the FC del Sur in June (Locobase 4762), but lacked both auxiliary axles. Like those of the Sur's, all four cylinders on the Sabana engines received their steam from 8" (203 mm) piston valves.
