After the ten express locomotives with a 2-4-0 wheel arrangement, the CLB ordered another series of twelve express locomotives in Esslingen. They date from the time when the locomotives were given names by the CLB and so they were all given the name of a town that is in what is now Poland or the Ukraine. Later the new locos were called Series I, while the older ones became Series II.

The third locomotive, called “Dnjepr”, was shown at the World Exhibition in Vienna in 1873 and apparently caused a stir because of its good looks and the large coupled wheels. Compared to the older locomotives, the driving wheels were significantly larger and the running axle, also fixed, was located under the driver's cab. Although the firebox now had a support, it was restricted in width by the large coupled wheels. Problems with this axle arrangement are also reported, which resulted in derailments due to icing in the area of the water cranes in winter. In addition, at higher speeds it was not an advantage for smooth running that the large coupled wheels were used instead of a leading axle

When they were nationalized in 1892, they were given the kkStB numbers 11.11 to 11.22. This resulted in the class 11 from 1905, but at that time only the 11.18 “Kherson” was left. It was in use until 1907, the remaining engines had already been retired between 1896 and 1902.
