The last design to flow from the fertile mind of Austria's leading locomotive designer, this Karl Golsdorf Prairie was designed for lighter service than his earlier Class 10 and Class 110 engines. Because it came in wartime, the 910 combined elements of several other designs. The boiler was first used on the Class 429.9, the Krau+-Helmoltz truck first appeared on the 310. Because the 910 was smaller, Golsdorf resorted to an Adams radial truck under the firebox.
It proved to be a fast and powerful design, although the boiler was a bit small for the piston volume. Concerns over bearing wear kept the maximum operating speed to 90 km/h (55 mph) although tests showed the locomotive rode easily at 120 km/h (75 mph).
Used briefly on the Orient Express, the 910s went to the CSD in 1919 as that railway's class 364.0. Based in Decfn, they served the Prague-Nimburg and Lundenburg to Brunn & Prerau trains as well. All 22 were taken into the DRG when the Third Reich took over Czechoslovakia in 1938; they were class BR 35.501-35.522.
The last 364.0/BR 500 was withdrawn in 1950.
