The . No. 1 to 3 were vierfachgekuppelte narrow gauge - Tender locomotives the Rózsahegy-Korytniczai helyi érdekü vasút (RKV) in the then upper Hungary .
history
The three locomotives were built in 1908 by the Hungarian machine works MÁVAG in Budapest with the serial numbers 1993 to 1995 for the 760 mm- gauge narrow-gauge railway from Ružomberok to Korytnica in what is now Slovakia . Corresponding locomotives had already been delivered to the Vajdahunyad - Gyálar coal railway as MÁVAG Type 51 .
During the First World War , the machines were confiscated in 1916 in exchange for other locomotives for use at the front in South Tyrol . The kuk Heeresbahn used the three locomotives from then on on the Fiemme Valley Railway and Val Gardena Railway lines serving as supply lines on the Dolomite front .
After the First World War they stayed in South Tyrol. As a replacement for several locomotives that were lost in the war, they came as R 1 to R 3 to the Mori – Arco – Riva local railway in Trentino . There they were in use until the line was closed in 1933.
In 1960 they were retired by the Italian State Railways (FS).
technical features
The engine of the locomotives was remarkable. The first and fourth coupling axles were designed as Klien-Lindner hollow axles in order to achieve good arching . Only the second and third axles, which together formed the fixed wheelbase of 1400 millimeters, were fixed. The power transmission from the coupling rods to the axles took place via Hall cranks .
The water supply was in side containers next to the boiler; the coal in a box behind the driver's cab.
