The steam locomotive series SB 480 was a freight train - steam locomotive series of the Austrian Southern Railway (SB), the last three copies of which have already been delivered to the BBÖ .
history
The Südbahn owned machines from the kkStB 180 and kkStB 80 series designed by Karl Gölsdorf . Both were designed for the North Bohemian routes with a weak superstructure and therefore with a low axle weight. The Südbahn therefore endeavored to procure a series of locomotives for its routes that would use a boiler with a higher axle load. The first three copies of the 480 series delivered by the StEG locomotive factory in 1921 developed 1,250 hp at 50 km / h, which was an increase of approx. 10% compared to the 80,900 series. The last three of the total of only six series have already been taken over by the BBÖ as their successor due to financial difficulties on the southern railway .
The machines were used on the Semmering Railway for four decades as tensioning and pushing locomotives.
After the annexation of Austria to the German Reich in 1938, the Deutsche Reichsbahn classified them as 57 601-606.
After the Second World War , all six machines came to the ÖBB as series 257 , which equipped three of them with Giesl ejectors and boiler pipe throttling in 1957 . Most recently they were used in front of groupage trains near Vienna and were not retired until 1966.
One example of this series is preserved in the Strasshof Railway Museum . A second copy was dismantled in 2006 and scrapped for the purpose of obtaining spare parts. This measure was discussed controversially in Austria.
