Die Lokomotive, June 1904
The 57 series IId machines of the Kaiser Ferdinands-Nordbahn were the first Atlantic locomotives in Europe. The trailing axle was fixed in the frame, but was only just behind the second coupled axle. In the kkStB they became the class 308 and the twelve machines from 1908 with steam dryers became the 308.5. Three units were converted to the class 227 with a 4-6-0 wheel arrangement. The Warsaw-Vienna Railway received 18 locomotives that were almost identical. After World War I almost half ended up in either Czechoslovakia or Poland. Regardless of the operator, the locomotives had almost completely disappeared around 1940.
