The steam locomotive series KFNB IIIb 1,2 was a series of passenger trains with a tender of the Kaiser Ferdinands-Nordbahn (KFNB).

The StEG locomotive factory , the Bethel Henry Strousberg locomotive factory in Hanover and the Wiener Neustädter Lokomotivfabrik supplied 52 of these type 1B locomotives from 1867 to 1873 . The KFNB gave the machines of the IIIb series the numbers 110–161 . The vehicles were also given names, e.g. B. the first one was called NORDSTERN " and the last one delivered was LEMBERG .

The old, inefficient boilers were gradually exchanged for better ones. In this context, the machines that had not yet been converted were assigned to the IIIb1 series , the converted to the IIIb2 series . In 1907 there were only two class IIIb1 locomotives that had not been converted.

The machines were mainly stationed in Lundenburg and hauled the passenger trains to Zellerndorf and Grußbach / Schönau .

At the kk Austrian State Railways (kkStB) they formed the 121 series after the nationalization of the KFNB .

After the First World War , six of them came into the possession of the Polish state railway PKP . The remaining machines came to the Austrian railway company BBÖ , which they decommissioned by 1926.
