Vienna-Gloggnitz 4-4-0 Locomotives in Austria


Class Details by Steve Llanso of Sweat House Media

Class Grosse Gloggnitzer (Locobase 552)

Similar to the Kleine (Small) Gloggnitzers, but preceding them into service. See Kleine entry for details.

The Grosse (Large) Gloggnitzers had larger boilers, slightly larger cylinders, and smaller drivers. They ran over the Murzzuschlag and Laibach section pulling 145- to 160-ton passenger trains and 190- to 350-ton freights. This performance is said to have exceeded expectations.


Class Kleine Gloggnitzer (Locobase 553)

Data from Reder (1974); supplemental information from [], accessed 16 August 2006. The latter's specifications are used in this entry because they are more complete. Note, however, that data from this period are notoriously unreliable.

John Haswell, a Scot in charge of the Vienna-and-Gloggnitz Railway's locomotive department, adopted the American Norris Brothers layout of a 4-4-0 with outside cylinders inclined over a 4-wheel truck, equalized driving axles, and slide valves mounted over the cylinders but operated by inside gear. Norris's engines had impressed most of Europe with their power, fuel consumption levels, and reliability. Haswell's development included a radial truck (rather than center-pivot) and a quarter-sphere firebox.

The principal differences between the Kleine (Small) Gloggnitzers and the Grosse (Large) Gloggnitzers is in cylinder dimensions and driving wheel diameters. Kleine Gloggnitzers could pull 122 to 135-ton passenger trains over the Murzzuschlag and Laibach section (with 0.17% ruling grade) or 155 to 290-ton freights.
