Standardization of the express 4-4-0 on Austrian railroads resulted in this design, which combined an outside frame (with eccentrics flailing), the firebox mounted between the driving axles, an outside frame, and the Elbel truck with its rigid ball-and-socket pivot. Also, the engines showed the common Kobel cabbage stack, adopted to reduce sparks.

Data from [], last accessed 13 September 2006. One of Karl Golsdorf's classic two-cylinder compounds. Physically, the design is dominated by a pair of steam domes connected by a thick pipe. An usually long span between leading truck axles helped to spread the weight over the entire engine wheelbase. Such a long wheelbase, combined with the placement of the truck pivot 3 1/2" behind its center,

Although Engineering reported the railway as the Kaiser Ferdinan Nordbahn, the editors added a footnote noting that while Emil Tilp was at time of writing the KFNB's locomotive superintendent, these engines were not produced for the KFNB. The only Wiener Neustadt four-coupled with bogie express locomotives in that period went to the Sudbahn. Even so, this class appears to be the predecessor to the IIc class described in Locobase 4691. Compared to the later engine, however, the design had taller drivers. Tilp's requirements were for a locomotive that could haul 125-140 trailing tons on a line 20% of which presented adverse gradients of 1 in 70 (1.4%) at 60 kph (38 mph). In the summer, the same locomotive would haul an additional coach at 55 kph (35 mph). In trials one of the locomotives hauled 16 coaches over a 350 km (218 mile) distance in six hours including several stoppages (an average of 58 kph/36 mph). Engineering explained that the engine needed a relatively large grate because KFNB burned poor hard coal that evaporated a meager 3.5 lb of water per pound (1.59 kg per 0.454 kg) of coal. Great attention was paid to smooth running at express speeds. The bogie was connected to the buffer beam under the smokebox by short links on each side. Each link was fitted with universal joint. Further links under the center of the truck also used universal joints. "This construction has been adopted, " reported Engineering, to ensure "the greatest possible steadiness of the engine in rounding curves ...we are informed that in consequence of this complete system of flexible connection the engine runs with great smoothness even at speeds of 62 miles [100 kph]."
