Lower Austrian State Railways No. 30 to 33
Austria-Hungary 1905 4 produced
Numbers 30 to 33 of the NÖLB were four three-axle steam railcars built in 1905 and 1906. The boilers and the running gear came from Komarek, while the bodies were constructed by Rohrbacher. Compared to the smaller numbers 20 and 21, they had an additional leading axle and a larger boiler. Like their predecessors, they had a steam dryer. Two were operated on the Ernstbrunn–Mistelbach–Hohenau line and one on the Korneuburg–Ernstbrunn line. The fourth one served as a reserve. All were sold in 1919 and 1920.
