KFNB No. 202 ‘Gnadendorf’ (Wiener Neustadt 3194/1888), location and date unknown. This engine later became 104.19, was passed over to ČSD and withdrawn in April 1923, still bearing her KkStB number. Source: www.pl.wikipedia.org.

 

 

 

 

 

 

In 1884 Kaiser-Ferdinands-Nordbahn (KFNB) took delivery of seven light express locomotives from Wiener Neustadt, classed IIc, which featured single-expansion steam engines, 2-2-0 axle arrangement and 1862 mm drivers. Further engines of this type were ordered in 1887 and production continued until 1893, totaling 41 examples from Wiener Neustadt (nineteen), Krauss Linz (ten) and WLF (twelve), with service numbers 184 through 224. Last six engines from WLF featured improved pony trucks, which replaced the obsolete Camper-type units. In 1906, after KFNB had been incorporated into state railways KkStB, they were classed 104 and given consecutive service numbers.

Three examples were withdrawn in early 1918 and, of the remaining 38, the majority (28) went to Czechoslovakia. Three were initially kept by BBÖ, but eventually were also handed over to ČSD. Of these, only nineteen survived until the introduction of new designation system in mid-1920s and were classed 264.6. Last of them, 264.610 (former 104.26, Wiener Neustadt 3343/1889) was withdrawn in August 1930 and for a few more years remained in use as a stationary boiler. One engine, 104.28 (Wiener Neustadt 3345/1889) was taken over by Romanian state railways CFR and retained her original service number; she was withdrawn before 1934, but exact date is not known.

Polish state railways acquired six locomotives of this type, built between 1884 and 1887 by Wiener Neustadt (four) and Krauss Linz (two). Most probably they were to be classed Pd11, although some sources suggest Od14; the latter seems less probable, as their drivers’ diameter qualified them as express engines. Due to obsolescence, they saw little service and all had been withdrawn before the new designation system was actually introduced. Allocation of new service numbers to individual examples is not known. No locomotive of this type has survived until today.
