The third type of six-coupled locomotives of the Engerth type on the Southern State Railway consisted of eight units that 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 class 22 and from 1864 the 28 series on the Southern Railway. Six of the eight locomotives in this class were converted 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 engines that had not been converted initially remained in use. However, the No. 660 “Lipitta” was retired in 1885 and the No. 664 “Prosecco” in 1888.
