Vienna-Raab Railway “Wien II” bis “Altmannsdorf”
The “Wien II” of the Vienna-Raab Railway was the first locomotive built in the factory led by John Haswell, later known as the factory of the StEG. It was completed in 1840 and had still been constructed in the same fashion as Norris locomotives, with a 4-2-0 wheel arrangement and an overhanging firebox. It had outside cylinders since the builder was not yet able to manufacture crank axles. It was followed by five similar locomotives called “Hietzing”, “Schönbrunn”, “Belvedere”, “Liechtenstein” and “Altmannsdorf”. Their dimensions, especially in the boiler, were not identical. While the first one had 75 tubes, the others either had 70 or 78. “Schönbrunn” had a boiler explosion in 1847, but the others passed on to the SStB in 1853. They were withdrawn in 1857.
