The manufacture of railway vehicles was difficult because at that time in Austria there were still no iron foundries and none of the workers had the training for this type of work.
One of the biggest influences on the development of locomotive construction in Austria was the first manager of the factory, John Haswell, who led it from 1840 to 1882.
In 1855, the factory went into the ownership of the Staats-Eisenbahn-Gesellschaft (State Railway Company) or StEG (full title: k.k.
landesbefugte Maschinen-Fabrik in Wien der privilegirten österreichisch-ungarischen Staats-Eisenbahn-Gesellschaft), which had the factory expanded in size.
Due mainly to the consequences of the First World War, there was only a low demand for locomotives within the reduced Austrian national territory.
