The steam locomotive series SB 35a was a freight train - steam locomotive series of the Austrian Southern Railway (SB).
history
Soon after the opening of the Semmering Railway , it became clear that four-coupled locomotives were the right choice for such mountain routes. After the series SB 33 and SB 34 , the Südbahn continued on this route. Under the direction of the machine director Louis Adolf Gölsdorf , the Wiener Neustädter Lokomotivfabrik ( Sigl ) designed an even more powerful four-way coupled locomotive series with an inner frame and an external Stephenson control. From this series, Wr. Neustadt and the StEG locomotive factory 25 units each and the Floridsdorf locomotive factory five units in 1871 and 1872.
The machines were a great success; so they pulled 210 t over a 25 ‰ incline. They were used on the Semmering , on the Brennerbahn and in the karst areas . The original chimneys were replaced by cone or Kobel chimneys, which slightly changed the height of the machines.
Having become aware of the great success of this series, the Northern Italian Railway borrowed a machine in 1872 in order to undertake test drives on the steep ramp near Genoa . This led to an order for 60 locomotives of this type from Sigl in Wr. Neustadt. From 1873 to 1905 a machine of this type was also manufactured in Italy by Miani and 33 by Maffei in Munich . The FS classified them as series 420 .
After the First World War , 20 of the SB machines came to the FS as series 452 , 23 to the railways of the Kingdom of Serbs, Croats and Slovenes , 16 of which were later designated as JDŽ 132 , and twelve as series 471 to the BBÖ , which they retired by 1934.
During the Second World War , three of the Yugoslav machines came to the Deutsche Reichsbahn as 55.5601-5603 .
