Southern State Railway “Nabresina” to “Prosecco”

Austrian Southern Railway class 22 (old) and class 28

Austria-Hungary 1857 8 produced
Die Lokomotive, July 1929

The third type of six-coupled locomotives of the Engerth type on the Southern State Railway consisted of eight which were delivered in 1857 by the Esslingen machine works. They had the same wheel diameter as the second type, but were slightly heavier. From 1858 they became the 22 and from 1864 class 28 on the Southern Railway. Six of the eight locomotives in this class were rebuilt between 1869 and 1886 into tender locomotives with a 0-6-0 wheel arrangement. The boiler was pushed forward to distribute the weight evenly over the axles. These six locomotives all remained in service until at least 1897, the last being the last rebuilt No. 665 “Reifnitz”, which was retired in 1907. The two locomotives which had not been rebuilt initially remained in use. However, the No. 660 “Lipitta” was retired in 1885 and the No. 664 “Prosecco” in 1888.
