Imperial-Royal Northern State Railway “Sedletz” to “Hohenmauth”
State Railway Company No. 2 to 7
When the k.k. Nördliche Staatsbahn (Northern State Railway) received its first six locomotives in 1842, they were at the same time the first locomotives built at the Wiener Neustadt factory. As this railway had mostly flat lines in today's Czechia, the 4-2-0 locomotives from Norris were used as a model. They were named “Sedletz”, “Florenz”, “Plass”, “Carolinenthal”, “Hohenstadt” and “Hohenmauth”.
In his first years, manufacturer Wenzel Günther wasn't able to make all parts in his own shops. So the complete boiler was made by Seßler of Krieglach, while other parts had to be cast by other firms. In 1855, when the NStB came to the StEG, they got the numbers 2 to 7. It didn't take long for these locomotives to become too weak with around 80 hp. Additionally, the frame was to weak to support a more powerful boiler and larger cylinders. So they were retired between 1860 and 1864.
