Apparently the first delivered small tank locomotives NkNb 1–3 were not very satisfactory in terms of performance. The NkNb therefore ordered four stronger tank locomotives from the StEG locomotive factory , which were delivered in 1891 and 1892. The machines were compared to the car numbers 1-3, larger wheels , could be so admitted as h speed 40 km /. The steam dome sat on the first boiler shot, the sandom on the second. The vehicles were given the road numbers 4–7.
In the course of nationalization , the NkNb steam locomotives came to the Hungarian State Railways MÁV , which they classified as Category XIIk initially with the operating numbers 5641–5644, later as 6641–6644. From 1911 the locomotives formed the 383 series.
