KkStB Class 30

The kkStB Class 90 were a class of 2-6-2T locomotives designed by Karl Gölsdorf for use of the Vienna Stadtbahn of the Imperial Royal Austrian State Railways (kaiserlich-königliche österreichische Staatsbahnen). They were built by Lokomotivfabrik Floridsdorf, Wiener Neustädter Lokomotivfabrik and Lokomotivfabrik der StEG between 1895 and 1901. After 1921 they were later operated by Bundesbahnen Österreich (BBÖ) and following the annexation of Austria in 1938, they were incorporated within Deutsche Reichsbahn Class 90.10. After the restoration of Austria they became Österreichische Bundesbahnen (ÖBB) class 90.
