The locomotives of the series SDZ 500 were wet steam Mallet - tank locomotives with the wheel arrangement (1 'C)' C in Bosnian gauge , which in 1913 by Borsig for the former Serbian State Railways Srpske državne Železnice were built (SDZ). In 1916 Henschel & Sohn delivered a second series to the kuk Heeresbahn Süd as kukHB VI . The railways of the Kingdom of Serbs, Croats and Slovenes (SHS) designated the wet steam mallets as SHS VIc7 , the Yugoslav State Railways (JDŽ) as JDŽ 91.

description

Locomotive No. 6025 of the kuk Heeresbahn
JDŽ 91-031 in Sarajevo

The Srpske Državne Železnice (SDŽ) procured five heavy wet steam mallet locomotives near Borsig in Berlin in 1913 for the steep, narrow-gauge line from Paraćin to Zaječar . They were able to 15 ‰ slope 350 tonnes to 28 180 tonnes ‰ trailer to transport h with an average speed of 15 km /. To make it easier to negotiate curves with a 60 meter radius, the running axle and the first coupling axle were connected to a Krauss-Helmholtz steering frame and the flange of the first coupling axle of the rear chassis was weakened. The two undercarriages were connected by a single pin and a joint. Control is based on the Heusinger system .

Because after the occupation of Serbia the existing locomotives were not sufficient for the operation of the routes taken over, Henschel & Sohn in Kassel built another 46 of the proven Mallet locomotives for the kuk Transportleitung Wien, 34 of which were intended for the kuk Heeresbahn Süd. After the First World War, like the first series, the 34 locomotives came to the railways of the Kingdom of Serbs, Croats and Slovenes (SHS). There they were classified as VIc7 together with other mallet locomotives according to the BHStB series scheme. With the Yugoslav State Railways (JDŽ) they were given the designation JDŽ 91 in 1933 and operated mainly on the Bosnian Eastern Railway and on over the Šargan Mountains from Sarajevo to Užice.

Further machines of the second series were stationed at the military railway in Klausen in South Tyrol in October 1918 and came to Italy after the war. Since there was no use there for locomotives with 760 mm gauge , the mallets were re-gauged to 950 mm (Italian meter gauge ) and used as FMS 151–159 in Sardinia .
