Data from Commissioner Anderson, Reports of the United States Commissioners to the Paris Universal Exposition , 1878, pp.437-440.
Commissioner Anderson praised the kKStB for the way in which its designs made the best use of some indifferent coal, "... a small and inferior article of fuel supplied by the coal mines of Kladno, near Prague, and Rossnitz, near Vienna. Kladno's coal "...give a short flame, coke with difficulty, and contain a little sulphur and 20 per cent. of cinders and stone." This was mixed with the Rossnitz product of mixed coals, which also coked poorly, "...are very sulphurous ...and contain 20 to 25 per cent. of ashes."
Pretty poor stuff and, the Commissioner observed, "Employed alone, they work badly, but mixed with the slack coal from the Kladno mines each seems, to some extent, to correct the defects of the other." The railroad also mixed in some high-quality Steyerdorf coal, which was quite good. Locobase notes that the rate of consumption per 100 ton-miles varied by only two pounds between the Kladno and the Steyerdorf coal (16 lb vs 14 lb).
The boilers and rods were made of Martin steel and the latter were grooved to reduce weight. The tube plate was made of copper. See Locobase 4612 for a later batch that had a still bigger grate.
