Data from [], accessed 14 August 2006.See also O S Nock, "Austrian State Railways", Railways at the Zenith of Steam-1920-1940 (New York: Macmillan Company, 1970-pub in England by Blandford Press) Plate 10, page 109. When the class fell into the hands of the Third Reich, the DRG classed them as BR 33.10. Works numbers were (StEG) were 4693-4702 in 1923, 4703-4710 in 1924 (113.01-113.18), 4735-4744 in 1925 (113.26-113.35), and 4820-4824 (113.36-113.40) in 1927. Floridsdorf delivered works numbers 2866-2872 (113.19-113.25) in 1924.
Derived from the Sudbahn's pair of trial horses (Locobase 2470), these Twelve-wheelers were the OBB's standard passenger engines in the Austrian mountains. OS Nock described them as "singularly angular and unaesthetic locomotives" and Eagleson and Zeil (1973) claimed that Austrian locomotives, along with Greek engines, were the filthiest in Europe.
Unattractive they may have been, but the locomotives generated a healthy amount of power and were well-liked by their crews despite their relatively low maximum speed of 85 km/h (53 mph). "They may not have been handsome engines," added Nock, "but they certainly proved worth extensive modernisation in teh early 1950s, when they were fitted with the Giesl ejector [exhaust system]."
A tally in 1953 showed 33 of the 40 still in service and the last wasn't retired until 1968.
Many were later fitted with the Giesl ejector nozzle stack.
