The reference for locomotives and railcars

Vienna-Raab Railway “Philadelphia”

Austria-Hungary 1837 1 produced
Die Lokomotive, July 1917

With the founding of the Wien-Raaber Eisenbahn, a locomotive was initially required that could be used for the construction of the line and for further tests. Georg Simon Sina von Hodos saw the simply built locomotives from Norris in the USA as ideal for this and therefore bought one of these used. It was hoped that maintenance would be easier due to the outside cylinders, which did not require a cranked axle.

The locomotive arrived in Vienna in April 1838 and was named “Philadelphia” after its origin. Although it was used as planned during the construction work, when the line opened it was too weak to carry passenger trains. Now that more powerful locomotives had been procured from England, the “Philadelphia” continued to be used for other tasks. In 1853 it came to the Southern State Railway and was retired in 1857.
