k.u.k. HB VI Series Locomotive JDZ 92
Military Occupation of Bosnia and Herzegovina (Manufactured 1918)
Variously called: kuk HB VI / SHS VIc7 / JDŽ 92 / JŽ 92
The locomotives of the kuk HB VI series were superheated steam mallet tender locomotives with the wheel arrangement (1'C)C in Bosnian gauge , which came to Serbia in 1918 from Henschel & Sohn to the kuk Army Railway just as WWI was ending. In 1922 Henschel built another 30 machines as reparations for Serbia. The railways of the Kingdom of Serbs, Croats and Slovenes (SHS) designated the superheated mallets as SHS VIc7 , the Yugoslav State Railways (JDŽ) as JDŽ 92.
In 1917, the German Traffic Engineering Examination Commission of the Experimental Department of Military Transportation ordered 50 newly developed Mallet tender locomotives with Schmidt superheaters from Henschel & Sohn in Kassel , 20 of which were intended for use in Serbia. Since the construction of the new series, developed from the SDŽ 500 mallet tank locomotive , took some time, only one or two machines were delivered to Serbia until the end of the war -
After the end of the war, more machines were taken over, so that a total of 19 of these superheated steam locomotives came into the stock of the railways of the Kingdom of Serbs, Croats and Slovenes (SHS). They were used in eastern Bosnia and Serbia and, together with other Mallet locomotives , were assigned to the VIc7 series according to the BHStB series scheme. A second series of 30 machines followed in 1922, again from Henschel, as reparations .
In 1933, the Yugoslavian State Railways (JDŽ) gave the superheated steam mallets the designation JDŽ 92 and proved themselves even better than their predecessors, the JDŽ 91 . They were used extensively in Serbia until 1968. The last ones were still in operation in March 1970. The JŽ 92-
