The Galician Carl Ludwig Railway originated from the k.k. Eastern State Railways and operated their lines east of Kraków. These routes are now in Poland and the Ukraine and went via Lemberg and Tarnopol to the border of the Russian Empire. In 1870, ten express locomotives with a 2-4-0 wheel arrangement were ordered from Maschinenfabrik Esslingen, which were classified as IId. In 1878 and 1882 a total of eight more were delivered by the Wiener Neustädter Lokomotivfabrik and designated IIe. As was usual at the time, all three axles were firmly mounted in the frame, but the overall wheelbase of just 3.32 meters still ensured sufficient ability to negotiate curves.

The locomotives from Esslingen were given the names of towns along the CLB routes, the others only numbers. After the railway was nationalized again in 1892, they were given the numbers 2231-2248 by the kkStB. In the same year they received new boilers. Some locomotives on the Kronprinz-Rudolf-Bahn also had numbers starting at 2201, but these became series 122 from 1905 and the CLB locomotives became series 22. All but three locomotives were retired between 1906 and 1915. The fate of the remaining ones was lost in 1917 in the turmoil of war, but probably two pieces came to Poland and one to Russia.
