0-6-0 Steam Locomotives in Austria

Class 27 (Locobase 7786)

Data from [], accessed 16 August 2006.

The 0.7% grade from Wiener Neustadt to Gloggnitz demanded more traction and the Haswell supplied these four -- FAHRAFELD, RAXALPE, LEOBERSDORF, and FELIXDORF -- which proved capable of pulling 300 tons up the hill. The design featured the use of equalization between the rear two axles. Cylinders drove outside, valves were actuated inside.

When tested on the more challenging Semmeringbahn in 1854, however, they could only manage 90 tons each. Over the next several years the engines operated in Hungary, although their retirement dates cannot be determined.

Class 29 / 49 (Locobase 543)

Joseph Hall's Austrian 2-4-0s (see Series 467-539) inspired a class of 202 strictly freight 0-6-0s built from 1860 to 1872. Everything was outside: cylinders, valves, eccentric rods and cranks, springs. These low-drivered engines were dominated by their Kobel spark-arresting stacks and large sand and steam domes. Some were driven on the middle axle, others (those needing as short a wheelbase as possible for tightly curving lines) on the rear axle.

Website members.aon.at/sik/stef/lok671.htm (Dec 2001) credits the example run as a museum piece with 460-mm diameter (18.11") cylinders. This yields a tractive effort calculated at 18,742 lb and a factor of adhesion of 4.47.

Class 34 (Locobase 6954)

Data from Titre Exposition universelle internationale de 1878 a Paris. Rapports du jury internationale..Volume Groupe VI - Classe 64. Rapport sur le materiel des chemins de fer. p. 50 (cnum.cnam.fr/CGI/fpage.cgi?8XAE277-11.1/54/100/312/0/0 (accessed 1 September 2005). Works numbers were 232-236 in 1878.

The jury describes this as similar to the Bourbonnnais type of freight locomotive. The design is credited to the Sudbahn's chief engineer Gottschalk, who sought a dual-purpose engine that could pull passenger trains up the Brenner Line's 2.5% grade at 17-20 kph (10.6-12.4 mph) or freight trains on the Sudbahn's main line. All three axles were located ahead of the Belpaire firebox. Such was the size and number of tubes, said the jury, that the operator was assured of "une grande production de vapeur".
