Austrian Southern 0-8-0 Locomotives in Austria
Class Details by Steve Llanso of Sweat House Media
Class 34 (Locobase 545)
Data from "SB 34" in Wikipedia at [
], last accessed 21 April 2022. See also Gustav Reder (Michael Reynolds, trans), The World of Steam Locomotives (New York: Putnam, 1974). Works numbers were 784-793 in 1867.
These engines were enlarged versions of the basic Wien Raab design with outside frames and outside valve gear turning Hall-type cranks that entered service on Austrian Sudbahn's Brenner line in 1867. Its appearance featured a tall, capped dome, raised firebox, and inversely tapered stack.
A speed limit of 36 kph (22 mph) indicates the vertical profile they class usually worked, a layout that demanded more tractive effort than speed of advance. The type was more common in Hungary where many were delivered from 1869 to 1891. The Series 34s were the pattern for the first German eight-coupleds (Ludwigs Railroad in Hessen, 1869-1872) as well as seeing some service in Russia.
