The KFNB IIa was a superheated steam express train with a tender locomotive of the Kaiser Ferdinands-Nordbahn (KFNB).
The Wiener Neustadt locomotive factory delivered 1,907 pieces of eight two-cylinder - steam -Lokomotiven the type 2C to the KFNB. The machines were designated as series IIa and had the numbers 1001-1008. You should replace the KFNB IId (kkStB 308), as it was too weak for the increasing train weights.
A 2'C1 4v machine was originally planned. However, based on the Prussian model ( P 8 ), it was decided to use a 2C locomotive with a superheater.
Since at that time Austria had little experience with superheated steam machines, there were many operational problems that were gradually resolved.
After the nationalization of the KFNB in 1906, the kk Austrian State Railways (kkStB) took over the eight machines and gave them the series designation 111 . However, they have been replaced in their traditional area by the kkStB 210 series . Half of the 111s were then in action in Vienna and half in Prerau .
After the First World War , all eight machines came to the ČSD , which they classified as series 365.1 and which were taken out of service by 1958.
