The steam locomotive series BBÖ 181 was a freight train - steam locomotive series of the Austrian Federal Railroad (BBÖ).
history
After the First World War , twin designs became more and more popular because of the lower acquisition and operating costs. Since the now small Austria had lost almost all of its coal reserves, the coal-saving compound machines were reconsidered and 27 of the 81s under construction in the Wiener Neustadt locomotive factory were equipped with compound engines. Due to the large low-pressure cylinder, the leading axis had to be moved further forward. The boiler pressure could be increased to 18 atm compared to the 81 series.
The number than 181 machines were designated 1922 / 23 delivered and used mainly in the mountain service. However, due to falling coal prices, interest in locomotives with compound engines was soon lost again, and so the 181 series was the last compound locomotive series built in Austria.
In 1938 they all came to the Deutsche Reichsbahn as 58 801–827 , but the Deutsche Reichsbahn was also not interested in them. After the Second World War , eight of them came to ÖBB , which they planned as series 158 , but which were retired in 1953. 15 machines came as class 29 to the Yugoslav State Railways (JDŽ) and were initially given the numbers 29-101-115. In 1948 they were renumbered to JDŽ 29-028-042.
