Oesterreichischen Sudbahn 2-4-0 Locomotives in Austria

Class Details by Steve Llanso of Sweat House Media

Class 467-539 (Locobase 548)

Data from Gustav Reder (Michael Reynolds, trans), The world of steam locomotives (New York: Putnam, 1974)

Joseph Hall's eccentric crank and bearing collar was applied to many Austrian locomotives after he became manager of the Gunther Locomotive Works in Vienna in 1859. Although he only held the post for a year before becoming superintendent of the Sudbahn's rail-rolling mill, a series of 2-4-0s were built to his design from 1859 to 1873. Most were built with an overhanging firebox and had the square, Crampton-style throttle fitted near the stack. The last series moved the firebox forward and had 78-in drivers. (The specifications suggest that the boiler certainly had the necessary size; it isn't clear whether the firebox and cylinders were enlarged in later series.)

A later group had the cylinders relocated between the carrying axle and the front driving axle. See also Series 29 for the six-coupled freight engines.
