Data from "Twelve-Coupled Tank Locomotive, Java State Railways", Locomotive Magazine, Volume 18 (15 August 1912), p. 163, and Metzeltin, "Fourteen-Wheeled (1 F 1) Superheated-Steam Tank Locomotive, Java State Railway", Zeitschrift des Vereines deutscher Ingenieure, translated for Bulletin of the International Railway Congress, July 1913, items 621.132.6 (.92) & 623.616 (.92), pp. 585, et seq.

Nicely proportioned, if massive, tank that switched or handled freight traffic over relatively short distances. Its stability came from placing the tanks 450 mm (17.7") lower than earlier designs
The running gear included a rigid wheelbase of only 3.75 m (12 ft 3 5/8 in). The first and sixth axles were given considerable side play within a Golsdorf axle arrangement while both the leading and trailing axles were Adams radial types.
Nine-inch (229 mm) piston valves supplied steam to the cylinders.
Doug Self, commented that the wheel arrangement acquired a name that specifically referred to this class: "Javanic". He notes that "Although they coped with the work , the tight curves caused severe flange wear on the leading drivers, and they were moved to other mountain lines with milder curves, where they were very successful."
See Indra Krishnamurti at [] for roster of 2-12-2Ts delivered in four batches by Hanomag (1912-1915 -- 6450, 6813-6821, 7362-7367) and Werkspoor (1915 -- 372-374).
Heating surface data differs in dspace.dial.pipex.com/javatour/ambarawa/locos/F1015.htm, a site for the Ambarawa Railway Museum maintained by Rob Dickinson. Dickinson, in describing 7366 of the last Hanomag batch, gives 122.2 sq m for heating surface, which converts to 1,315 sq ft. Superheat and grate areas are nearly identical with the above. Weight on the drivers is higher at 137,347 lb (62,300 kg) while overall engine weight is 173,502 lb (78,700 kg).
Krishnamurti, at [], says F10 01-23 had 120.2 sq m/1,293 sq ft of EHS, 36 sq m /387 sq ft) of SHS. F10 24-28 he lists has having 110.8 sq m/1,192 sq ft of EHS.
